As her best friend is pulled into the supernatural underworld, Branwyn isn’t about to sit on the sidelines. Unfortunately, Branwyn is decidedly mortal, and in the supernatural underworld, humans are weak and helpless, no better than toys, tools and prey. But she isn’t having any of that. Branwyn wants to face the world on her own terms, mortal or not. When she strikes a bargain with an imprisoned faerie, Branwyn thinks she’s found the solution. He’ll teach her magic and she’ll use that magic on his behalf. It’s a great deal, until she discovers what the faeries really want from her: there’s a door that only she can open…

Being the daughter of a supernatural monster makes it hard to have friends, especially when your father is determined to make you follow in his footsteps. It's especially tough at Halloween, when all good little monsters should be wreaking havoc, not trying to go unnoticed. But AT makes do with her magical dogs and the local ghosts. It’s almost a life…until the Wild Hunt shows up. On this All Hallow's Day, they'll finally be released to pursue their ultimate ambition: hunting down every ghost in the mortal world. And that’s only the beginning. The only way to stop them is to venture into the heart of a cursed city and steal the source of their power. That's hardly a problem for the daughter of a monster--until AT realizes she needs more than shadows and magic to get where she's going. She needs friends, too. And that is terrifying.
