All Stacy Justice wants to do is recover from the bizarre couple of weeks she's had -- a whirlwind kicked off by the arson attack on her cousin's bar, the Black Opal. But just when life should be settling down, a fourteen-year-old girl named Ivy appears on Stacy's doorstep, claiming to be her sister. Ivy says their mother's life is in danger and insists that the family's magic is crucial to saving her. Sure, Ivy has Stacy's fiery red hair and green eyes -- but is she really her sister? And can the secretive teen be trusted with magic? Then a man is found dead at Stacy's grandmother's bed-and-breakfast, and she has no choice but to see where Ivy's story leads. Strange warnings appear at every turn, including the disappearance of the family's Blessed Book, and it seems someone is out to kill Stacy -- again.
