I've heard mixed reviews about this book, but I decided to finally read it.  Honestly, I wasn't very impressed.  The plot consists of the main character Bianca (aka The Duff) hooking up with her high school's most notorious playboy Wesley even though she laments over and over again how much she "hates" him.  There's a lot of angst and every chapter is filled with either Bianca hooking up with Wesley or thinking about their next rendezvous (or chastising herself for wanting to be with him all the time).  It wasn't horrible to read but this type of story has been told many times and has been executed a lot better by other authors.
