New Book Ideas?

The worst part about finishing a book is trying to find one to read next. Nothing is seeming to spark my interest much. I'm sick of the typical girly lovey-dovey novels, and I'm looking for something different. Maybe I'll try to find a funny book to read. I could always go for a good laugh. But I also like books with a good meaning and theme behind it. So I really don't know which direction I should go. So if anybody actually reads my posts, it would be FABULOUS if you could give me a couple suggestions on what to read next. Please and thank you!
