From the author of October, October, winner of the Yoto Carnegie Medal, comes a heartbreaking and heart-warming story about sisterhood, found family and accepting love in the most unusual and unknown places. Fen and Rey were found curled up small and tight in the fiery fur of the foxes at the very edge of the wildlands. Fen is loud and fierce and free.

She feels a connection to foxes and a calling from the wild that she's desperate to return to. Rey is quiet and shy and an expert on nature. She reads about the birds, feeds the lands and nurtures the world around her.

They are twin sisters. Different and the same. Separate and connected. They will always have each other, even if they don't have a mother and don't know their beginning. But they do want answers. Answers to who their mother is and where she might be. What their story is and how it began. So when a fox appears late one night at the house, Fen and Rey see it as a sign - it's here to lead them to their truth, find their real family and fill the missing piece they have felt since they were born. But the wildlands are exactly that: wild.

They are wicked and cruel and brutal and this journey will be harder and more life changing than either Fen or Rey ever imagined ...
