Along for the Ride by Sarah Dessen

I read every Sarah Dessen book we get in.  I love her characters and often feel sorta sad when the book is over.  This effort is no exception.  In it, a studiously mature Auden spends the summer before college with her father's new family at the ocean, and it changes her life.  She connects with fellow insomniac, Eli, and they begin a quest to experience all the things she missed growing up--like food fights, learning how to ride a bike, delivering papers, etc.  Gradually Auden's opinions of people and situations change--and relationships with her divorced parents, new stepmother, new girlfriends, and Eli all reach a new level.
