Rivals bound by magic. A secret that could destroy them both. Yulin is the youngest librarian to ever be inducted into the enigmatic Library of Mages. With a promising career ahead of her, she doesn’t have time for anything outside of her work. And she especially doesn’t have time for Masai Ujara, her irritating rival librarian, who is somehow always one step ahead. But Yulin has a secret. She's in possession of an ancient book with stronger magic than even the library knows—and she's studying it without the library's permission. When Masai discovers her indiscretion, he offers to cover for her ... as long as she lets him in on the secret. But neither of them could have prepared for the darker truths they’re about to uncover, truths that will force them to tether themselves together with magic to defeat a dark mage and reveal a terrifying secret—one that will push them tantalizingly close to the edge of shadow, and to each other.
