Alien invasion? Zombies? Vampires? Aria is an average 19-year-old with average problems - until zombies landed their UFO in her backyard. If Aria wants to survive, she'll need some help, and who better than a pirate captain, a steampunk inventor, a bazooka-wielding killer, and a deranged Englishman who insists he is Doctor Who? Stuck in a war between vampires and zombie-walking Weeches, Aria and her eccentric crew take a stand for mankind as they fight for their right to survive. Hey, if you have to slaughter zombies and vampires, why not enjoy it?
