Carla Santini. She's the Italian exchange student who's coming to stay with Jamie Hogan and her family. Jamie can hardly wait to spend time with Carla--it will be just like having a sister her own age. But Jamie has a lot to do before Carla arrives. There are rooms to organize and sleeping arrangements to decide. There are friends to tell the big news to, and four months of activities to schedule. And Jamie has her boyfriend, Andy, to think about. She wants to include him in all of the plans. Jamie spends hours imagining what Carla will be like. When Jamie finally sees her guest, why can't she believe her eyes?
