The Sky is Everywhere, by Jandy Nelson

From Booklist

Lennie has always been the companion pony to her sister Bailey’s race horse. When Bailey dies suddenly while rehearsing the lead in Romeo and Juliet, Lennie is thrust into the spotlight. A normally reserved band geek who reads Wuthering Heights like a manifesto, Lennie is not prepared to deal with her grief. Nor is she equipped to confront the affection she feels for her dead sister’s fiancé. Adding to her emotional roller coaster is the gorgeous, musically gifted new boy in town who is clearly in love with her. Lennie is sympathetic, believable, and complex. Readers will identify with her and root for her to finally make the first steps toward healing. Nelson incorporates poems, written by Lennie and left for the wind to carry away, that help readers delve deeper into her heart. Bonus: teens unfamiliar with Wuthering Heights will likely want to find out what all the fuss is about. A story of love, loss, and healing that will resonate with readers long after they have finished reading.
