This Lullaby by Sarah Dessen has to be one of those books that I love to re-read over and over again. I've read it about 3 or 4 time since me 10th grade year of high school and it's still a great book. I never get bored of it. This is the description of it on Goodreads:
"When it comes to relationships, Remy doesn't mess around. After all, she'd learned all there is to know from her mother, who's currently working on husband number five. But there's something about Dexter that seems to defy all of Remy's rules. He certainly doesn't seem like Mr. Right. For some reason, however, Remy just can't seem to shake him. Could it be that Remy's starting to understand what those love songs are all about?"
This book is a lot better then this description gives it. I highly suggest you read this book.
