When a mismatched group of people wakes up and sees their city burning to ashes, they have no idea what happened. They don't remember the dead rising to kill their friends. They don't remember the end of the world. There is just a dark spot in their heads where the memories should be. But one of them rescues a girl from the wreckage, a woman who has seemingly cut off her own arm. And now she'll tell them what happened. The catch? The apocalypse is all she remembers. She is a girl born and bred in war. And now she'll help them find out why the Revenant destroyed their world, and who destroyed their home, and in the process, hopefully, discover who she is.
