Does anyone have any book suggestions?

I'm looking for some new books to read, and I'm also trying to read new kinds of books. I've read Harry Potter, the Darkest Power trilogy, The Hunger Games, A Series of Unfortunate Events, The Spiderwick Chronicles. So these are the books I read but I'm also looking to read something else like self-help, horror, or non-fiction. I don't want heavy or really sad self-help books; I want them to be happy and uplifting and positive. The horror can't be really bloody or gruesome like saw or chain saw massacre, but suspenseful and interesting. I appreciate your suggestions :)
