Emma's sister is missing. Her parents have spent all their savings on the search. And now the family has no choice but to live in a ramshackle trailer park on the edge of the forst, next door to down-and-out harpies, hags, and trolls. Emma wonders if she'll ever see Helena, and if she'll ever feel happy, again.
Then she makes a friend.
A smooth-talking, dirty-furred cat named Jack. He's got a razor-sharp plan to rescue Emma's sister. He just wants one small favor in return...
