Eve Levine - half-demon, black witch and devoted mother - has been dead for three years. She has a great house, an interesting love life and can't be killed again - which comes in handy when you've made as many enemies as Eve. Yes, the afterlife isn't too bad - all she needs to do is find a way to communicate with her daughter Savannah and she'll be happy. But fate - or more exactly, the Fates - have other plans. Eve owes them a favour, and they've just called it in. An evil spirit called the Nix has escaped from hell. She feeds on chaos and death, and is very good at persuading people to kill for her. The Fates want Eve to hunt her down before she does any more damage, but the Nix is a dangerous enemy - previous hunters have been sent mad in the process. As if that's not problem enough, it turns out that the only way to stop her is with an angel's sword. And Eve's no angel.
