Sarah Dessen books are fabulous, the book Twenty Boy Summer by Sarah Ockler, The Sky is Everywhere by Jandy Nelson is probably one of my favorites, as well as The Lonely Hearts Club by Elizabeth Eulberg. (:
Off the top of my head, "The Bridges of Madison County" - James Waller - the book, not the movie. If you really like a good romance tied with crying your guts out - read anything by Nicholas Sparks. I'm assuming you are looking for light reading and not the classics - if you want to read classic romances - you know, the ones that will most likely change your life (also known as "literature") - you can usually Google a listing - and many of them are free to read online or downloaded to an e-reader - like a kindle or an iPad or similar tablet computer.
