Zugzwang

I had a seventy-three point six chance of surviving the zombie apocalypse. The aliens got me instead. I'm... wait, I probably shouldn't tell you my name. But I was at a gymnastics meet when it happened, and then I woke up and it was cold, I was nauseous, the Trainers showed up and started literally barking, and things got really complicated. There's some sort of sport? Vaguely related to chess, I think? And I'm not absolutely certain about what happens if we lose, but I don't want to find out.

Zugzwang is a YA sci-fi adventure, and a self-sustained prequel for Pawn, by J.C. Ahern.
