Sera has no memory of her life before. Before captivity, before experiments, before the only lifeline she had was the voice of a boy in the cell next to hers. Before G. G wishes he could forget everything before Sera brought him back to life. Forget his memories as a ruthless mercenary on an alternate version of Earth. Forget that he was part of an experiment simply known as Alpha. Now on the run from their captors and in need of an antidote to save his life, G and Sera's clock is ticking. And they'll have to gamble everything on the bond they forged in captivity if they want to survive.
