Tamsin Greene comes from a long line of witches, and she was supposed to be one of the most Talented among them. But Tamsin's magic never showed up. Now seventeen, Tamsin attends boarding school in Manhattan, far from her family. But when a handsome young professor mistakes her for her very Talented sister, Tamsin agrees to find a lost family heirloom for him. The search—and the stranger—will prove to be more sinister than they first appeared, ultimately sending Tamsin on a treasure hunt through time that will unlock the secret of her true identity, unearth the sins of her family, and unleash a power so vengeful that it could destroy them all. This is a spellbinding display of storytelling that will exhilarate, enthrall, and thoroughly enchant.

“[MacCullough] has created an enormously sympathetic character in Tamsin, whose itchy relationship with her family will resonate with teens struggling to define themselves. Characters, setting, conflict—all develop nicely to create a light urban fantasy that goes down easy and will have readers asking for its sequel.”—Kirkus Reviews  “With the glut of contemporary romantic supernatural tales, this will be popular, but the action, drama, and great potential for compelling sequels set it apart from the crowd.”—Booklist "MacCullough's writing is evocative without distracting from her story; readers will identify with Tam's desire to create a space away from parental expectations and take comfort that even extraordinary families make mistakes."--Publishers Weekly —
