Baba Yaga's Assistant by Marika McCoola
I remember reading a Baba Yaga story once as a kid in a collection of "spooky" stories for Halloween. It was the only exposure to Baba Yaga I ever had growing up, which is a shame because they really are fantastic folk tales. The heroines in these stories rely on a combination of bravery, kindness, and cleverness. Their virtues allow them to rescue themselves (plus they must be "good" as Baba Yaga eats "bad" kids). While Emily Carroll's illustration style isn't my favorite, it is well suited to this story of a young woman unhappy with her life who seeks out Baba Yaga.
