Tory and her friends celebrate the success of the second mission, but they are urgently called back to their time: Napoleon is about to invade England. Can the young magicians stop the army? In desperation, the guys ask Rebecca, an untrained telepath from 1940, to come to 1804 and make Napoleon change his mind before it's too late. Rebecca promises to help in any way she can, although she is not sure that her strength is enough. She is willing to sacrifice her life and relationship with Nick Rainford to repay her debt to them for saving her family. The mission takes Tori and Rebecca and their friends to the center of the army, where Napoleon is planning an invasion. And although their success may save England, they may still face not the sweetest consequences of their decisions when they return home.
