Wintergirls

Lia + Cassie, bestfriends linked by their paired eating disorders until Cassie decided to get better by cutting Lia out and Lia cycled out of her most recent inpatient program. Then Cassie dies and her ghost haunts Lia through her final spiral into anorexia.

I've got a thing for eating disorder stories, this one did some interesting things with the text and felt pretty true to some of the memoirs I've read. It really sucked me in right through to the end (not sure I was totally convinced by it but, so it goes.)
