Two stepsisters...
one summer in London...
one heir to the throne.
The race is on.
Helene Masterson and Alexis Worth are best friends who also happen to be stepsisters. When Helene lands a chance-of-a-lifetime summer internship in London, Alexis simply has to go too—and she takes her gigantic crush on a certain prince with her. To make their summer royally interesting, punky Helene and preppy Alexis make a bet that could change their lives forever: Which one will hook Prince William by summer's end? These forever friends learn that competition can be fun, but when it gets out of control, their friendship is tested. No doubt these girls are in for one fun and crazy summer!
