ACOTAR's Future: Unpacking Books 6, 7, and That 'Mystery of Part 4'
Published on June 4, 2026

Sarah J. Maas built something truly special with Prythian. Millions have fallen for its intricate lore, unforgettable characters, and, let's be honest, that incredible high-stakes romance. The A Court of Thorns and Roses (ACOTAR) series isn't just a fantasy staple anymore; it's a phenomenon. Every new book sends fans into a frenzy. After we all devoured A Court of Silver Flames, that fourth full-length novel, our minds immediately jumped ahead. What's next? Everyone's buzzing about "ACOTAR 6," "ACOTAR 7," and this mysterious "Part 4." So, let's unpack what we know, what we don't, and all the wild theories about where our favorite High Fae are headed. It's time to talk about the multi-part release strategy and what the future holds for this beloved universe.
First, A Quick Look at the ACOTAR Books So Far
Before we jump into the future, let's just quickly list the books we've got so far. The main saga currently includes five full-length novels and one novella:
- A Court of Thorns and Roses (ACOTAR)
- A Court of Mist and Fury (ACOMAF)
- A Court of Wings and Ruin (ACOWAR)
- A Court of Frost and Starlight (ACOFAS – a novella)
- A Court of Silver Flames (ACOSF)
A Court of Silver Flames was a big moment. It completely shifted perspective, moving away from Feyre Archeron's sole viewpoint to focus mainly on Nesta Archeron and Cassian. This change really showed Sarah J. Maas's intention to explore other characters and their journeys within the sprawling world of Prythian. Honestly, the success of ACOSF solidified the idea that the ACOTAR universe is big enough to support many different protagonist perspectives. It promises a continued narrative that deepens the world, rather than neatly wrapping it up.
So, What's Actually Confirmed for ACOTAR's Future?

While we don't have specific titles or detailed synopses yet, Sarah J. Maas has publicly confirmed her long-term plans for the ACOTAR series. She's assured fans the saga is far from over. Everyone knows the author has a multi-book deal with Bloomsbury, her publisher, to keep the ACOTAR story going.
According to various reports and interviews, Sarah J. Maas is contracted for at least three more full-length ACOTAR novels after A Court of Silver Flames. That means the next book, which fans are calling "ACOTAR 5" (since ACOSF was the fourth main novel), is definitely coming. And so are two more after that: "ACOTAR 6" and "ACOTAR 7." This commitment to more books ensures we'll have a rich continuation of the series for years.
But here's the catch: precise release dates for these highly anticipated books aren't available yet. Sarah J. Maas famously works on several series at once, including her Crescent City series and the now-finished Throne of Glass saga. This staggered writing approach means fans often wait between ACOTAR installments as she dedicates time to her other beloved worlds. For example, her next book is The Labyrinth of Flame, the fourth in her Crescent City series, due in January 2025. This suggests the next ACOTAR novel would likely follow that release, making a late 2025 or 2026 release for ACOTAR 5 a plausible, though unconfirmed, timeline.
What's the Deal with This 'Mystery of Part 4'?
The phrase "Mystery of Part 4" has caused some real head-scratching within the ACOTAR fandom. As we just mentioned, A Court of Silver Flames is numerically the fourth full-length novel. So, if "Part 4" refers to a specific book, it'd typically be ACOSF. But the prompt talks about "ACOTAR 6, 7, and the Mystery of Part 4," which makes it sound like "Part 4" is something after ACOSF, or at least a different way of looking at things.
This phrasing probably comes from one of two places. Both are rooted in how SJM has talked about the series' structure or how fans have interpreted its developing story arcs:
-
The "Next Book" as the Fourth Major Arc: Sarah J. Maas has hinted that the series might be organized into distinct arcs, perhaps each focusing on different protagonists or big storylines. The first three books (ACOTAR, ACOMAF, ACOWAR) clearly centered on Feyre and Rhysand's journey. Then ACOSF shifted to Nesta and Cassian. This felt like a new "arc" or "part" of the series. If we think of Feyre's arc as "Part 1," and Nesta's arc (ACOSF included) as "Part 2," then the next full-length novel (ACOTAR 5) would logically kick off "Part 3" of this grander narrative. However, maybe some fans or earlier ideas viewed ACOSF as "Part 3," making the next book (ACOTAR 5) the start of "Part 4" of the entire saga, especially if they considered ACOFAS as a distinct, in-between piece. This idea sees "Part" as a segment of the big story, not just a book count.
-
An Older Multi-Book Plan or Unofficial Title: Authors often have initial ideas for how many books a series will be or how the story will unfold. It's possible Maas might have, at some point, casually discussed a four-part structure for the whole saga, or maybe an early deal included a "Part 4" as a conceptual division rather than a strict numerical book. As series grow, these early plans can change and expand, which could lead to the "mystery" of what "Part 4" might have specifically meant, especially if the series has gone beyond its initial scope. Honestly, there isn't any widely cited official statement from SJM that clearly divides the series into "Part 1, Part 2, Part 3, Part 4" in a way that would make "Part 4" a distinct, upcoming mystery book separate from the numerical order. So, the "Mystery of Part 4" is most likely a fan question related to the next big shift in the series' narrative focus, following Feyre's and Nesta's stories. For our discussion, we're going to treat "Part 4" as referring to the untitled ACOTAR 5, which will kick off the next major character arc.
Who's Up Next? ACOTAR 5's Potential Stars

With Feyre's and Nesta's main stories (for now) explored, the focus for ACOTAR 5 (what the prompt calls the "Mystery of Part 4") is the most immediate and intense subject of fan speculation. Most theories point to two key characters: Elain Archeron and Azriel.
Elain Archeron's Journey
Elain, the middle Archeron sister, has always been a bit of a puzzle. Her gentle nature, Fae transformation, and developing powers, plus her tangled relationships, make her a perfect candidate for a protagonist.
- The Elain-Lucien-Azriel Love Triangle: One of the most talked-about aspects of Elain's potential story is her complicated romantic situation. She's mated to Lucien Vanserra, a bond she's largely avoided. At the same time, there's a quiet, undeniable tension between her and Azriel, Rhysand's Shadowsinger. An ACOTAR 5 centered on Elain would absolutely dive into this intricate triangle, exploring the difference between Fae mating bonds and true love and choice.
- Developing Powers and Identity: Elain has unique powers connected to foresight and gardening. An Elain-focused book would be a great chance to explore these abilities more deeply, maybe even revealing her true Fae lineage or destiny. Her journey to find her own voice and strength after her traumatic transformation and living in her sisters' shadows would be a truly compelling narrative.
- Connection to the Human Lands: Elain's human past is still a strong pull. Her story could lead to more exploration of the human lands, potentially uncovering new threats or allies from across the wall.
Azriel's Mysterious Past and Future
Azriel, the enigmatic High Lord's Shadowsinger, is another top contender for the next protagonist. His brooding nature, formidable skills, and shadowed past make him a fascinating character just waiting for more development.
- Unveiling Azriel's History: Fans have long begged for more insight into Azriel's traumatic upbringing and his training as an assassin. An Azriel-focused book could finally pull back the curtain on his past, revealing where his shadow abilities came from and the full weight of his burdens.
- The Mor-Azriel Dynamic: The unresolved tension and history between Azriel and Mor, another member of the Inner Circle, could be a central emotional conflict. Exploring their past and present would really add depth to both characters.
- Developing Relationships: Beyond Mor and Elain, an Azriel book could dig into his brotherhood with Rhysand and Cassian, his role as a spy, and his interactions with other powerful figures in Prythian. His story offers a unique perspective on the political landscape and the threats hiding in the shadows.
While both Elain and Azriel are strong contenders, many fan theories suggest ACOTAR 5 might even feature a dual POV. Or maybe it'll be a central story where both characters play significant roles, given their intertwined destinies. Sarah J. Maas has a history of building up secondary characters before giving them their own narrative spotlight, and she's certainly laid a lot of groundwork for both Elain and Azriel in previous books.
Beyond Book 5: What About ACOTAR 6 and 7?
Looking further ahead to "ACOTAR 6" and "ACOTAR 7," the possibilities just explode. With ACOSF setting the stage, it's pretty clear these next books will keep shifting perspectives, giving other beloved characters their own moment in the sun.
Potential Protagonists for ACOTAR 6 and 7:
- Morrigan (Mor): The elusive and powerful Mor has a complex history, especially her bisexuality, her past with Azriel, and her role as the High Lord's cousin and ambassador. A book centered on Mor could explore her journey to find love and define her power, potentially delving into the Winter Court or other unexplored territories.
- Gwyneth Berdara & Emerie: These two, introduced in ACOSF, have shown incredible growth and potential. While they might not lead a main novel so soon, their stories could connect deeply with future protagonists or even get their own novellas. Their journey as Valkyries offers unique ways to explore new parts of Prythian and its conflicts.
- Varian & Cresseida (Eris & Nesta's potential future?): While less developed, there are so many minor characters and alliances to explore. Prythian's political landscape and its neighboring territories (like the Summer Court or lands beyond the wall) could offer plenty of opportunity for new heroes and heroines. The idea of Eris Vanserra, the controversial High Lord of the Autumn Court, eventually getting a redemption arc and a love interest is a consistent fan theory, though perhaps a longer shot for a direct protagonist role.
Expanding the World and Unraveling New Threats:
This ongoing saga isn't just about character development; it's about Prythian's ever-growing world. ACOTAR 6 and 7 will likely:
- Introduce New Territories and Courts: The series has hinted at other Courts, territories, and even continents beyond the current map. Future books could take us to unexplored regions, introducing new cultures, challenges, and magic systems.
- Uncover Ancient Lore and Prophecies: Prythian's magic and history run deep. Maas often plants seeds of ancient prophecies and forgotten histories that become super important later in the series. Future books will undoubtedly dig into more of this lore, revealing hidden truths about the Fae and their world.
- Face New Adversaries: While Koschei and Briar are current threats, Maas's larger universe of interconnected worlds (often theorized to include Crescent City and Throne of Glass) suggests threats might extend beyond internal Prythian conflicts. More powerful, ancient, or even inter-dimensional foes could pop up, requiring the combined strength of the High Lords and their allies.
- Address Lingering Political Tensions: The fragile peace brokered after the war with Hybern, the tensions between the Courts, and the ongoing struggles with the human lands provide a rich backdrop for political intrigue and conflict in upcoming installments.
Understanding SJM's Writing & Release Schedule

Knowing how Sarah J. Maas writes and publishes is crucial for managing our expectations for ACOTAR 5, 6, and 7.
- Interconnected Universe: Maas has increasingly woven connections between her series, especially ACOTAR and Crescent City. This interweaving demands careful planning and execution, which can definitely impact release schedules.
- Dedicated Writing Periods: Maas typically dedicates focused periods to each series. With Crescent City 4 confirmed for 2025, it implies that significant progress on the next ACOTAR book might be paused or only in early stages until then. This is common for authors with multiple successful series; it helps ensure quality and prevents burnout.
- Bloomsbury's Strategy: The publisher, Bloomsbury, plays a huge role in coordinating releases. Given ACOTAR's immense popularity, Bloomsbury will strategically schedule releases to maximize impact and keep fans engaged. Multi-book deals like Maas's are common and give both the author and publisher a clear plan for future content. The gap between ACOWAR (2017) and ACOSF (2021) was pretty long, partly filled by ACOFAS and other series. Fans should probably expect similar intervals for these next main novels.
The Fandom: Our Theories, Hype, and Constant Buzz
The ACOTAR fandom is easily one of the most active and passionate in modern fantasy. Websites like acotar.org thrive on the constant discussion, analysis, and speculation about every single aspect of the series.
- Fan Theories: From intricate theories about Elain's powers to detailed predictions about Azriel's mate, the fandom actively fills the gaps between books with creative and often insightful discussions. These theories don't just keep the series alive; they probably even influence the author by showing what parts of the world and characters resonate most with readers.
- Community Engagement: Social media platforms, forums, and fan art communities absolutely buzz with activity. Release announcements, cover reveals, or even subtle hints from Maas can send the fandom into a frenzy, showing just how much anticipation there is for "ACOTAR 5," "ACOTAR 6," and "ACOTAR 7."
- Impact of Cliffhangers: Maas is a master of cliffhangers and lingering questions. Every book leaves us desperate for the next installment. This clever storytelling fuels the demand for the multi-part release and keeps the "Mystery of Part 4" (the next immediate book, remember?) right at the forefront of discussions.
The Future of ACOTAR: It's Only Just Begun!
Good news, everyone: the ACOTAR saga isn't just a hopeful dream; it's a confirmed reality, with at least three more full-length novels promised to us. While that "Mystery of Part 4" likely refers to the much-anticipated next book, "ACOTAR 5," which we expect will shift focus to a new protagonist like Elain or Azriel, "ACOTAR 6" and "ACOTAR 7" offer the tantalizing promise of even deeper explorations into Prythian's lore, characters, and conflicts.
Sarah J. Maas has truly built a universe that allows for multiple narratives to unfold. It keeps the saga fresh and engaging. As we all wait for official announcements regarding titles and release dates, the vibrant ACOTAR community will keep dissecting every clue, sharing every theory, and celebrating every development, united in our love for a series that just keeps growing and enthralling us. The journey through Prythian is far from over. This multi-part release strategy ensures the magic, romance, and adventure will endure for many years to come. The future of ACOTAR is bright, expansive, and full of the enchanting mysteries that have made it such a beloved phenomenon.
