Jessie Stern's life has taken a turn to the weird. It started out great. On her 13th birthday she discovered she was going on a space bound scientific expedition with her dad. But before they even leave Earth she is chased by beings she never thought existed–the Time Shifters-a race that can control time. Along with her cousin Daniel, Jessie tries to stop the Time Shifters before they stop her.
