Anyone know any good books?

I can't get my next Twilight Saga book Eclipse so in the mean time I figured I'd go visit the Library in town (We have no books stores) I'm not quite sure on any good books. I love the Twilight series and I'm thinking of a book that might possibly be well sort of morbid maybe? Like a darker kind of book. I'm trying to see what styles capture my interests. I was thinking maybe about this book i heard of where a guy loved a girl and she married another man and this frustrated the man in love with the girl and he killed many people for her. But I would like it to be tied in with romance if possible. Some kind of a more intellectual book would be great ;>.<
