Life hasn't been easy since Jess returned from the "True" timeline. She goes through the motions, dreading the day her reality will vanish from exis-tence. What's worse, she's in love with the wrong version of her boyfriend. While he may look and act just like the version from the "True" timeline, something isn't right. Then Jess comes home one day to discover she has a new foster sister... Herself. Using Jess's middle name, Marie has been kicked out of several foster homes in the "True" timeline. Who better to care for her than her own parents, right? Despite starting out life as the exact same person, Jess and Marie couldn't be more different. After kick-ing Jess out of her own bedroom and hacking her Instagram account, Marie isn't going to make Jess's life any easier. When Jess's friends notice their similarities, they give Marie a makeover and have them switch places at school for a day. What seems like a harmless prank turns Jess's world upside down. For Marie, that's all just fun and games. The daugh-ter of a corrupt time-cop has more sinister plans.
