When empathic librarian Lilah helps authenticate a forbidden grimoire at the St. Augustine Special Collections Library, she doesn't expect to trigger a protective enchantment that shields her from reality itself. Now she and Raven Darbyshire, the last priest of a dying order, are trapped in shifting timelines where their own existence hangs by a thread.

Behind the library's secure walls lies a cursed artifact—The Book of Heroes, a record of reality-shaping figures that's becoming a weapon in the wrong hands. As pages vanish, so do the people written on them, their influence erased from existence. When Lilah discovers her former rival may be systematically unraveling reality, she and Raven must race to save not just the book, but a fractured world shaped by the priests within its pages—including themselves—before parallel dimensions collapse and ancient wards fail completely.
