Myla Lewis is a quasi-demon girl who loves two things: kicking ass and kicking ass. When souls want a trial by combat for their right to enter heaven, they go up against her in Purgatory’s Arena, and she hasn’t lost a battle yet. But when the demons start to act weird, even for demons, and the King of the Demons, Armageddon, shows up at Myla’s school, she knows that things are changing and it’s not looking good.
