When Earth started collapsing, the only thing that kept me going was that I was with my sister. No matter what happened, we promised each other we would never be apart. Well, last month, she was sent to a tribe on a different planet that had all of its women die years ago. Now, I'm about to follow her through the portal and into a whole new world where I'll apparently find a mate perfect for me. Only when I arrive, there are two aliens that catch my attention.
