Lia and Cassie were best friends. But something went wrong and Cassie changed. Now Cassie is dead and Lia has 33 unanswered calls on her phone, 33 messages from her ex-best friend, all sent the day she died. How did she die? Why did she cut herself off? While Lia searches for answers, she drives herself relentlessly down her own path to destruction - to be thin, strong, in control. And completely empty. Wintergirls is a powerful but intimate story of one girl's chilling descent into the all-consuming vortex of anorexia.
