The Lovely Bones by Alice Sebold
Here is a link to a more informative and more detailed review if you want to know more about the story. I always feel badly slamming a novel as I know how hard it is to write them. Nevertheless, it is an awful piece of work. To quote the reviewer linked above:
What makes the pointlessness of the novel so aggravating is the selection of subject matter: the rape and murder of a child (and the aftermath). I'm not suggesting that such subject matter should be off-limits for fiction, but I am suggesting that if an artist wants to go there, it'd better be worth the trip. In short, she'd better have something damned important to say that justifies (and indeed requires) the fictional portrayal of such horrors.Sebold doesn't.
