Along for the Ride, Someone Like You, Dreamland, and What Happened to Goodbye), so I'll keep this short and sweet.
High school junior Annabel Greene starts the school year as a loner. Something happened to her over the summer--something that she refuses to talk or even think about, something that turned her best friend Sophie completely against her, something that led her to isolate herself and basically become a social outcast. Annabel does local modelling and has been in several commercials and ad campaigns, but she can't seem to reconcile the happy-looking girl in the ads to her real, lonely, sad self.
One day, after her vicious ex-best friend launches a particularly nasty verbal attack at her, Annabel ends up in conversation with Owen, a giant of a young man who is constantly plugged in to his iPod and is known for his anger management issues. The two develop an unlikely friendship, and Annabel begins to catch Owen's tendency for radical honesty. Eventually, Annabel has to deal with things that haunt her, including the painful dynamics of her family, the traumatic event in her summer, and her seeming inability to hold on to friendships.
I really enjoyed this book. I felt like it had a heavier subject than some of Dessen's other novels, yet it wasn't depressing like Dreamland. I'd definitely recommend it to any chick lit reader.
