What's a really good book?

I got to do a book report on a book of my choice and i can't find any good ones...any help? No offense but im not really into all that 12 year old twilight and harry potter crap etc. Kinda looking for a mystery or really exciting book, you know twist, murders, betrayals all the works, if you have any suggestions even if it's not like what i just described but is still a really good book go ahead and post it. You never know
