Zombie Apocalypse: My RV Is a Doomsday Fortress

Betrayed by coworker Sophie in a freezing zombie apocalypse, Irene was left in the snow for zombies. Reborn on the company raffle day, she holds a luxury RV key while Sophie wins 100 tons of heating fuel. Last time Sophie tricked her into swapping. Now Irene keeps the RV, wins 50 million in the lottery and turns it into an armored, supply-packed fortress. As bitter cold and zombies close in, Sophie is doomed, and Irene drives away to survive.
