When she was seven, a horrific fey attack killed Donna Underwoods father and drove her mother mad. Her own nearly fatal injuries were fixed by alchemy—the iron tattoos branding her hands and arms. Now seventeen, Donna feels like a freak, doomed by the magical heritage that destroyed her parents and any chance she had for a normal life. Only her relationship with her best friend, Navin, is keeping her sane.

But when vicious wood elves abduct Navin, Donna is forced to accept her role in the centuries-old war between human alchemists and these darkest outcasts of Faerie. Assisted by Xan, a gorgeous guy with faery blood running through his veins and secrets of his own, Donna races to save Navin—even if it means betraying everything her parents fought to the death to protect.
