A librarian witch must use her bookish knowledge to track down a dangerous, magical tome, in this enchanting novel from New York Times bestselling author Jenn McKinlay. Thanks to her training as a librarian and newfound magical abilities, Zoe Ziakas thinks she has a handle on her job at the Museum of Literature, safeguarding the secret collection of enchanted tomes known as the Books of Dubious Origin. But when Jasper Griffin – the colleague she’s been crushing on – discovers their latest acquisition has been stolen, Zoe is no longer sure. Full of dark magic, The Book of Shadows has unquestionable power, its most nefarious trick the ability to alter people’s perception of reality. To save the world—and their department—from imminent danger and possible destruction, Zoe, Jasper, and the rest of the BODO team embark on a quest to track down the book and its thief. Between navigating a magical midnight market, fending off demons, and feeding their new pet hellhound, the team's magical abilities are nearly maxed out. But when the thief unleashes the Book of Shadows’ darkest spell, Zoe and her crew will face their toughest challenge: separating fact from fiction before everything they hold dear is destroyed.
