All 12-year-old Marinka wants is a friend. A real friend. Not like her house with chicken legs. Sure, the house can play games like tag and hide-and-seek, but Marinka longs for a human companion. Someone she can talk to and share secrets with. But that's tough when your grandmother is a Yaga, a guardian who guides the dead into the afterlife. It's even harder when you live in a house that wanders all over the world...carrying you with it. Even worse, Marinka is being trained to be a Yaga. That means no school, no parties - and no playmates that stick around for more than a day.

My name is Scarlet Jones, and I'm a witch...of some kind. Probably. I grew up in a family full of strong Blood witches, in which my strange magic never belonged. I thought I was the only one of my kind out there, a true freak of nature, and I liked it that way.
