When a god controls an army of wraiths and corrupts magic itself, only a librarian can save the world. Odin is winning. Wraiths are everywhere. Jayne's mother is slipping away. And the only thing standing between order and magical apocalypse is one CIA Librarian who needs to prove herself worthy to a Japanese goddess. This book delivers: The penultimate battle with stakes that feel genuinely world-ending - Jayne and Tristan are officially united as soulmates (finally!) - Shapeshifting sisters, deadly supernatural realms, and divine trials - Sofia and Cillian training young adepts while everything falls apart - The fifth grimoire and its totem-IF Jayne can survive the gauntlet For readers who've invested in all four previous books : This is where it all comes together. The training academy. The romantic arcs. The family bonds. The magical system you've been learning. Everything matters now. Amaterasu doesn't grant power to the unworthy. Jayne must conquer riddles, rituals, and hidden reliquaries to claim the Spirits totem-and she's running out of time. One book left. One totem remaining. One impossible final battle. " The Book of Spirits is a fast-paced fantasy with so many of my favorite things—grimoires, layered character relationships, and a dragon! If you haven't started the Jayne series yet, now is your moment!" —Alisha Klapheke, USA Today Bestselling Author of the Bound by Dragons Series "...An adrenaline-fueled, action-packed adventure bursting with magic, love, friendship, and betrayal. Jayne Thorne and her merry band of allies are the best kind of found family, and I was on the edge of my seat hoping they'd all make it through their latest trials alive. As the penultimate book in the Jayne Thorne series, The Book of Spirits perfectly sets up the final installment, building to a thrilling conclusion that left me breathless." —Lauren Thoman, bestselling author of You Shouldn't Be Here "Joss Walker's The Book of Spirits has everything you could ever want in an epic fantasy: a spunky heroine, deep worldbuilding, magical monsters, a dash of romance, and a sentient dragon. The stakes are high and the pacing is fast making this the perfect read to dive into for a break from reality." —Meredith R. Lyons, award-winning author of Ghost Tamer "Vivid world-building, a page-turning mystery and a smart, adventurous heroine in the process of discovering her own power and learning from her mistakes makes for another great addition to an outstanding urban fantasy series." — Jayne Castle (Jayne Ann Krentz), New York Times bestselling author of the Harmony series, on Master of Shadows "A fast-paced, magical thrill ride that had me turning pages long into the night. Fans of female-forward urban fantasy with plenty of humor, hijinks, and heart won't want to miss it!" —C.J. Redwine, New York Times bestselling author of Rise of the Vicious Princess and the Ravenspire series, on Master of Shadows "Light-hearted books can get a bad rap, as though making readers smile is somehow a weakness on the author's part... Walker has a light touch with [her] prose, and the likable characters breeze through many of their interactions. Which isn't to say that Tomb of the Queen lacks gravitas. No, there's a good story here with real edge-of-the-seat moments... It's fun from start to finish, and I'm going to keep my eye out for more from this "new" author." — Charles de Lint, The Magazine of Mystery & Science Fiction, on Tomb of the Queen "Everything I love about urban fantasy." — John McDougall, Murder by the Book, on Tomb of the Queen Joss Walker is an award-winning fantasy author and the alter ego of New York Times bestselling thriller author J.T.
