I picked this book up (or rather put it on hold) after I saw it on an NPR book list by Gayle Foreman titled "Oh, To Be Young: The Year's Best Teen Reads." It is an interesting view into death and the grieving process of those "left behind." When Lennie's older sister, Bailey, dies unexpectedly, Lennie is tossed into a world unknown--where she is noticed, no longer in the shadow of her vibrant sister. Lennie always considered herself the "companion pony" to Bailey's racehorse, so her grief is explosive, as you might imagine. Nelson presents in a stunningly well-written narrative the emotional process that Lennie experiences--denial, guilt, passion, sorrow--all packaged in a coming-of-age type of story that will touch readers. 
 This story is truly in a league of its own. In my opinion, it's a must read. The language is beautiful. The main character is incredibly compelling and nuanced (even if other characters seem to fall flat--this one makes up for it). The storyline is realistic. It's beautiful. Read it.
