• Book of Memories (removes memories)
• Book of Shadows (creates concealment)
• Book of Pain (inflicts torture)
• Book of Illusions (creates false projections)
• Book of Despair (disarms opponents)

Each book grants singular, focused abilities rather than broad powers, making collectors seek multiple volumes to increase their capabilities.

Cassie Andrews receives The Book of Doors from a dying customer and initially uses it to travel the world with her roommate Izzy. After encountering dangerous book collectors, she's locked a decade in the past by villain Hugo Barbary, where she spends ten years with Mr. Webber, the book's original owner. Cassie ultimately discovers she created all the magical books herself when she entered a realm between worlds, sending them back through time. She survives multiple attacks and helps defeat the Woman by trapping her between worlds.

The Fox Library in The Book of Doors is a secret storehouse of magical books created by Drummond Fox's ancestor and protected using the Book of Shadows to prevent the Woman from finding it. Drummond Fox, known as the Librarian, inherited this collection from his grandfather Edmund and serves as its guardian. The library represents the greatest collection of magical books in the world, making it a prime target for collectors and villains throughout the story. By the novel's end, Cassie and her friends agree to band together at the Fox Library to protect remaining magical books from malicious use.

The Book of Doors features two primary antagonists: Hugo Barbary and the Woman. Barbary is a vicious collector who uses the Book of Pain to torture victims for information and pursues Cassie relentlessly for the Book of Doors. The Woman is a more ominous figure hunting all magical books and killed three of Drummond's friends years earlier. The story reveals that the Woman's evil behavior originated from pain magically withdrawn from Barbary entering her body as a young girl, explaining her transformation into a malevolent force.

The Book of Doors by Gareth Brown explores themes of power, responsibility, and the consequences of one's actions through Cassie's journey with magical artifacts. The novel examines friendship and family bonds as Cassie, Izzy, and Drummond band together against dangerous forces. Brown emphasizes the importance of travel and experiencing new places while addressing darker themes of violence, suffering, and how pain shapes people into villains. The story also explores grief, loss, and finding connection through shared experiences across time.

The Book of Doors concludes with Cassie and her friends defeating the Woman by stealing her magical books, replacing them with illusionary fakes, and ultimately trapping her in the empty realm between worlds. The revelation that Cassie herself created all the magical books by discharging her emotions in this between-worlds space explains their origins. Izzy survives her apparent death through the Book of Illusions, and Hugo Barbary is sent to the past to live with renewed perspective after his pain is removed. The friends unite at the Fox Library to protect the remaining magical books from future threats.

The Book of Doors is currently a standalone novel, not part of a series. Gareth Brown's debut was published in February 2024 and concludes with a complete story arc where the main conflict is resolved. However, Brown is working on a second novel titled The Society of Unknowable Objects, scheduled for publication in summer 2025 in both the UK and US. While this new book has a different title suggesting a separate story, it may explore similar themes of magical objects and mysterious collections.

The Book of Doors distinguishes itself as low fantasy or urban fantasy set in contemporary New York City rather than traditional fantasy worlds. Gareth Brown focuses intensely on character dynamics and emotional development over extensive world-building explanations, deliberately avoiding detailed exposition about how or why magical books exist. Each magical book possesses singular, specific powers rather than broad abilities, functioning as "honed, individual weapons" that create strategic complexity. The novel combines time travel mechanics with intimate character studies, emphasizing personal relationships and psychological depth alongside thrilling adventure sequences.
