A Gypsys Journey

I'm writing a post apocalyptic glance into the future. Short novel which may evolve into a series of books. Lead character is Mercy, and her journey is the main focus. She needs to find her sister and make it to the last shuttle South. Tension starts early when Mercy meets Beau and they learn more about each other. Survival and post-apocalyptic mutated biology. This is literally so action packed, I'm afraid I won't fit all the ideas into one book.
