Fans of Kate Forsyth will appreciate this tale of a young woman 15 years after she discovered the father she adored kidnapped her 16yr old mother and held her captive until the pair escaped when Helena was 12. Apparently (I say, because I’d never heard of it), there’s a (1858) Hans Christian Anderson fairytale called The Marsh King’s Daughter which centres around the child born to a princess captured by the evil Marsh King. And the plot of this book (told in the then, when Helena was young; and the now) unfolds in a way that kinda mirrors the fairytale.
