A slow-burning and lyrical thriller with an intoxicating blend of contemporary and fantasy from award-winning and critically acclaimed author Deirdre Sullivan.

Fifteen-year-old twins Madeline and Catlin move to a new life in Ballyfran, a strange isolated Irish town, a place where the earth is littered with small corpses and unspoken truths. A place where, for the last sixty years, teenage girls have gone missing in the surrounding mountains.

As distance grows between the twins - as Catlin falls in love, and Madeline begins to understand her own nascent witchcraft - Madeline discovers that Ballyfrann is a place full of predators. Not only foxes, owls and crows, but also supernatural beings who for many generations have congregated here to escape persecution.

When Catlin falls into the gravest danger of all, Madeline must ask herself who she really is, and who she wants to be - or rather, who she might have to become to save her sister.
