Identical twins Elizabeth and Jessica Wakefield and their friends at Sweet Valley Middle School are going camping! Elizabeth can't wait to spend a week swimming in the lake, sleeping in a tent, and roasting marshmallows over a bonfire. Best of all, the wilderness provides the perfect setting for a little romance with her sort-of boyfriend, Todd Wilkins. Romance is also in the air for Jessica. She has her eye on Dennis Asher, a cute seventh-grader who's new at school. But Jessica can't survive without a blow-dryer--how can she impress Dennis when she looks so terrible? So Jessica comes up with a brilliant scheme. She pushes her twin, who looks great while roughing it, on Dennis--and tells him Elizabeth is Jessica! Todd is very confused, and Elizabeth is furious! Elizabeth fights back...by making sure that Jessica's plan works a little too well...
