Rachel Wyatt's goals in life use to be very average. Go to college, get a job, have a family. The normal goals for any sixteen year old girl. But all of those goals changed when the invasion happened and civilization was wiped out. Now Rachel and her mother Eva (a former army veteran) are fighting with a group known as the 2nd Mass, who's goal is to take back earth from the aliens. Rachel's life may be drastically different from before but Rachel refuses to let that ruin her. Instead she's going to let it turn her into someone who's never going to stop fighting; someone who will never give up.
