Elsewhere - Gabrielle Zevin
I read this after my 14-year old cousin got killed in a car accident two years ago.
Though some of the storyline might be a little far fetched, the book brought consolance to her mother at the time, making her have faith that her daughter was still around somewhere and possibly looking down at us from that place. So apart from liking the story objectively (if that's entirely possible), I'm also giving it 4 stars because it helped some of my family members overcome their grief a little easier.
