Sister Switch

Sister Switch is a series which contains six novels written by actress Maryam Wells. The series features two teenage sisters that magically swap bodies because of awish made on a shooting star now they are trapped in each other's bodies.

Plot
The two Jenkins sisters share a household and a high school, but both feel that they have little else in common. 17-year-old Alex's days revolve around being popular, dressing stylishly, and spending time with her jock boyfriend, while exerting minimal effort academically. While 15-year-old Gaby is socially reserved, admiring her older sister's popularity from a distance while excelling in her studies, particularly science and mathematics. Gaby and Alex don't get along well at all, with Gaby resenting her reliance on her frequently late sister for a ride to school and Alex preferring not to be seen with her less-than-cool younger sister.
