Apocalyptic: Revenge

In her previous life, Luna's best friend and boyfriend betrayed her trust after she graciously let them into her home during the deadly zombie outbreak. They stole her rations, took her weapons, kicked her out of her shelter, and refused to save her when she was injured. They watched as she was killed by the zombies, torn to shreds. After the pain subsided, Luna opened her eyes again to realize that she had gone back in time to three months before the zombie outbreak started. This time, she was going to build her safe haven ahead of time, and more importantly, take revenge on those who caused her death in her previous lifetime!
