Lizzie and Evie are inseparable. They walk home from school together, sleep over at each other's houses, even flirt with boys together. And they tell each other everything. Or at least, that's what Lizzie thinks - until Evie goes missing, and Lizzie suddenly realizes their friendship wasn't quite what she thought.
