Jinx - Meg Cabot

Jinx is a spine-tingling tale of magic and mayhem from New York Times bestselling author Meg Cabot.
It wasn't just the power failure the night Jean Honeychurch was born that earned her the nickname Jinx: misfortune seems to follow her wherever she goes. Which is why she's been shipped off to New York to stay with relatives - including her sophisticated cousin Tory - until the trouble she's caused back in her small hometown dies down.
Tory couldn't care less about Jinx - until Jinx's chronic bad luck starts wreaking havoc in Tory's perfect world. Only then does Jinx learn that beneath Tory's big-city glamour lies a world of hatred and revenge. And now Jean's jinx could be the only thing that can save her life . . .
