Well I must start with "The Holy Grail" of romantic books The Twilight Saga Collection which includes Twilight, New Moon, Eclipse and Breaking Dawn. This series really set me on my journey to find more fantastic books. I've read the entire series at least eight times, including the few chapters of Midnight Sun on Stephenie Meyer web page http://stepheniemeyer.com/. I can't get enough of this series and would recommend it to anyone who wants to be swept away into a great love story. WARNING!! You will get addicted so set up some serious reading time in your schedules ;)
(M)- So far the firsts 3 books have been confirmed by Summit to be made into movies. Let's all cross our fingers for Breaking Dawn.
