If an android is built to mimic humans, are her pain, joy, and love real? Or simply an artifact of programming? In the mid-2300s, Earth is devastated by climate change. With the planet failing, a team of scientists must race to create the ultimate scout: R.A.C.H.E.L. Tasked with finding a new home for mankind, by the time Rachel is ready, it's too late. Instead of being the one to lead humanity to the stars, she is left behind by the very people she was meant to save.
R.A.C.H.E.L. Undying follows Rachel as she struggles to find her place in a ruined Earth where only a fraction of humanity remains. Her original purpose lost to her forever, Rachel has to come to terms with her new reality, and, in doing so, discovers that being human doesn't just mean being made of flesh and blood.
