On a quest to rescue their father in a fantasy realm, sisters Abbie and Mae are butting heads. Abbie is so preoccupied with old friends and enemies coming back to haunt her, it's like she's abandoning Mae all over again - just like she did when she disappeared for eight years, returning with a world of monsters. But as Mae sets off on her own in a foreign land, she learns the true story of Abbie's past. And it's more heroic than she ever imagined it could be.
