One Boy At a Time — Diana Gregory

Wendy Fong thinks her boyfriend's new popularity has gone to his head. Now that Jay Hammond is Stanford High's new swimming hero, he's become insufferable! Just to teach him a lesson, Wendy decides to break up with him until he goes back to being the sweet guy she used to know.

When she meets Marc Chandler, Wendy concocts a plan to make Jay jealous and bring them back together again. But there's one thing Wendy doesn't plan on -- she has more fun with Marc than with any other boy she's ever known. Now she thinks she's in love with both boys. And if Marc discovers her plan to get Jay back, Wendy could end up with no boyfriend at all!
