One year after her twin brother's death ,Teressa Clerke still refuses to believe the story. Then a scholarship sends her to Wyrmsbane Academy, a school hidden deep within supernatural territory. Her admission comes with one condition: she must tutor Brandon Mystica, the untouchable heir to one of the oldest Alpha bloodlines. Brandon wants nothing to do with her because he hates humans, avoids questions about his past, and seems determined to keep Teressa at a distance. But when Teressa follows him to his estate on a Blood Moon, she discovers the secret behind his hostility. He is a werewolf. Worse, his wolf recognizes her as his mate. Brandon rejects the bond, but neither of them can ignore the connection growing between them. As Teressa searches for answers about Theo’s death, anonymous letters from her penpal known only as M. begin appearing in the Inkwell Society, revealing secrets buried beneath Wyrmsbane. Then Teressa discovers that Brandon knew Theo. As attraction turns into trust and their forced proximity becomes something neither expected, Teressa is drawn deeper into a mystery involving missing records, a corrupt supernatural council, and Brandon’s exiled cousin, Alpha Callan. But the secret is the one hiding behind the letters. M knows far more about Teressa than anyone should. And when she finally discovers who has been writing to her, everything she thought she knew about Brandon and Theo’s death begins to unravel. At Wyrmsbane, blood carries power, secrets demand a price, and ink can reveal truths that were meant to stay buried. To uncover what happened to her brother, Teressa must decide how much she is willing to lose and whether she can trust the boy who may have been hiding the truth all along.
