Rowan Thorne's life as a quiet librarian in Perry, Georgia, is meticulously ordered. But when an ancient, cursed grimoire mysteriously appears and ignites a latent power within her, her world shatters. Whispers in the library become tangible threats, and the shadowed stranger she keeps seeing is no coincidence. Dorian Blackwood, a brooding 300-year-old vampire sworn to protect the balance between worlds, reveals a truth more fantastical—and dangerous—than any book she's read.

As Rowan grapples with her newfound abilities and the existence of a hidden supernatural society, an ancient evil stirs. Marius Volkov, a ruthless vampire bent on seizing the grimoire's power, unleashes his forces, drawing Rowan into a desperate fight for survival. With her quiet life obliterated and her heart increasingly entangled with the enigmatic Dorian, Rowan must embrace her destiny as a nascent witch or watch the world descend into chaos.
