One Boy Too Many — Emily Chase

Jane Barrett is in real trouble-- boy trouble. If Neal isn't sending her flowers from Boston, then Cary, a local student, is asking her for a date. Jane's friends can't believe Neal and Cary don't know about each other, but Jane can't find a way to tell them.
Jane's roommates are no comfort at all. Andy, wrapped up in tryouts for the school musical, thinks Jane is being dishonest. Toby, busy with tennis lessons, doesn't realize there's a problem. But when Neal visits Canby Hall, Jane can no longer hide the truth. Will she lose both boys when they find out about each other?
