Lia and Cassie are best friends, wintergirls frozen in fragile bodies, competitors in a deadly contest to see who can be the thinnest. But then Cassie suffers the ultimate loss--her life--and Lia is left behind, haunted by her friend's memory and rackedwith guilt for not being able to help save her. In her most powerfully moving novel since Speak, award-winning author Laurie Halse Anderson explores Lia's struggle, her painful path to recovery, and her desperate attempts to hold on to the most important thing of all: hope.
