In the fifth electrifying installment of the Joss Walker series, CIA Librarian Jayne Thorne faces her darkest hour as the world teeters on the brink of a magical war. With Odin, the all-father, controlling an army of Wraiths and corrupting magic itself, only Jayne can turn the tide by unlocking the secrets of the fabled Man'yoshu manuscripts and claiming the Spirits totem. As adepts emerge across the globe and the battle lines are drawn, Jayne's sister Sofia Thorne and her Rogue partner Cillian race to train a new generation of young adepts at their hidden magical academy. But even as they prepare for the coming storm, Jayne's mother Ruth Thorne teeters on the edge of succumbing forever to her Wraith form, a chilling reminder of the high cost of failure. Joined by her soulmate Tristan Labelle and his fiercely loyal shapeshifting sister Vivian as her Rogue guardian, Jayne must navigate treacherous supernatural realms and face formidable new foes to prove herself worthy of the Spirits totem. An ancient prophecy foretells that only the chosen CIA Librarian can wield this mystical object, bestowed by the elusive and demanding Japanese goddess Amaterasu herself, to cleanse the chaos Odin has unleashed. Pushing her librarian skills-and her relationships-to the breaking point, Jayne must conquer a deadly gauntlet of riddles, rituals and hidden reliquaries to retrieve the totem before her enemies claim it for their own nefarious ends. With the fate of magic itself hanging in the balance, THE BOOK OF SPIRITS propels the Joss Walker novels to thrilling new heights in a pulse-pounding tale of arcane intrigue, unlikely alliances, and the unbreakable bonds of love and loyalty forged in the fires of destiny.
