When Conor finds out mysterious Meurig is under a spell, he promises to help. Meurig’s immortal soul is trapped in a small white candle, and if anyone burns the candle away, Meurig will die. Conor and his friend Sara try to rescue it for him, but then it falls into the hands of his deadly enemy, the treacherous river-goddess Hafren.

And she will only give it back for a terrible price.

Catherine Fisher’s classic tale of magic, courage and music is set on the eerie Gwent levels, where the mists rise from the waterlogged fields, and no one is safe from the vengeance of the river.
