Vixen A.D., Book 2 - Lara X. Lust

After surviving the wastelands of Neo Mars, Mace begins life at Delta with Faye and Cinder. The colony—a massive USF base with fabricators, a mining operation, an AI, and much more—should be full of other survivors. But Delta is vacant. Where is everyone? What happened to the USF megacolony? The mutant germ burning through Neo Mars isn’t helping, either!
