Taryn and Jeff have lived next door to each other forever. It never really seemed to mattter that they were a girl and a boy; they were just friends. But when they hit sixth grade, everything changes, whether they want it to or not.
Middle school is full of new faces and new activities. Jeff makes the soccer team and acquires a ton of cool new friends. Taryn heads up the school carnival committee, trying to keep busy while the rest of the girls in her class go off the boy-crazy deep end. But when Jeff transforms into Mr. Popularity, Taryn can't believe it. When did he turn into such a boy? And what happened to her best friend?
