A world beyond her own.

A sea captain passes through the forgotten port of Wych Ferry, and whiles away an hour relating his traveller’s tales to young Rosamund Euden. He tells her that the stars are different, if you sail far enough, that the horizon isn’t quite real, not when you get there; he speaks of sea serpents and whales, and mysterious islands.

To an impressionable girl who has never left her home, the whales and strange stars of his stories come to symbolise the great outside world she longs to see. The sea captain moves on, unaware of the dramatic events he has set in action as Rosamund’s search for adventure leads her into a world of dangerous secrets in the marshlands of eighteenth century Kent.

Torn between loyalty to her uncles, and her desire to discover what lies beyond the marshes, Rosamund seeks help from an unexpected source. But who can she really trust?
