A beautifully illustrated story that successfully walks a fine line between never defanging Baba Yaga while still humanizing her enough to make you root for her. 
 Older teen Masha is pissed off. Her dad is getting remarried. Not only is the new step-sister a brutal beast of a brat, but Masha realizes that Dad has been ditching her to at dinner time to eat with his family-to-be. Angry at years of inattention coming to a head, Masha runs into the woods to become a servant to the witch Baba Yaga. 
 I was charmed by a few things. 
 1) I've always loved Baba Yaga, and the author obviously knows his stories. 
 2) Baba Yaga's chicken-legged hut acts absolutely adorable. 
 3) I like the way the story acts as if the modern world has come to pass with everyone just aware that there's a terrible witch in the forest. 
 It's a fun read that still managed to surprise me once or twice. Give it a few years and this will be a bedtime storybook in my house.
