Tabby Freeman and Lora Froggett go to the same school, but they live in totally opposite worlds. Tabby is rich, pretty, and the most popular girl in her class. But behind closed doors, her "perfect" life is rapidly coming apart at the seams.

On the other side, Lora is smart, timid, and the constant target of bullies. While struggling to survive the piranha-infested halls of her school, she becomes increasingly nervous that somebody might discover the unbearable truth about what's been happening to her family.

Despite their differences, Tabby and Lora have something in common - they're both harbouring dark secrets and a lot of pain. Although they've never been friends, a series of strange events causes their lives to crash together in ways neither could have ever imagined. And when the dust finally settles and all their secrets are forced out into the light, will the girls be saved ... or destroyed?
