This book deals with death. It deals with grief. And it doesn't do it in a way that glorifies grief, or simplifies it, or complicates it either. This book felt far heavier after reading it than it did prior to doing so. I wept at times reading this book, and pretty much non-stop for the whole last quarter of it too. All the emotions that these words caused me are now in between each page. This reading experience was down right cathartic. 
 Zentner just gets it. He gets grief, he gets young adults, he gets it all so damn right. I'm actually in awe of this book. I feel like it's flown under the radar and it really deserves more attention. The content is not sugar coated, or glossed over. The weight of grief, the permanence of death, the burden of guilt and the power of memories are all so carefully explored and entangled in the narrative that you cannot help but feel deeply and passionately for our protagonist, Carver, as he endures the tragic loss of his three best friends. 
 Be warned that this book does, as advertised, deal significantly with grief and death. It's a very emotional book, and certainly had me feeling a heck of a lot. I think it's also important for everyone. If not now, than probably at some point in your life. This is a new favourite book of mine.
