When Art's mother is accused of witchcraft and captured, she is determined to get her back - at any cost. A lyrical adventure with folklore at its heart, for fans of THE HOUSE WITH CHICKEN LEGS.

Twelve-year-old Art lives in a small village in Scotland. Her mother has always made potions that cure the sick, but now the townspeople say she is a witch. One cloudless night, Art's mother is arrested and taken to England.

Art mounts her horse, taking a sword, a tightrope, and a herbal recipe book, and begins a journey through wild forests, using nature's signs and symbols to guide her.

But will she spot the signs from the omens? Will she reach her mother, before it's too late?

In the wake of a tempest hitting her town, Morwenna is left to take care of a stranger washed ashore. The storm is just another of many that have plagued the town for years - people blame the tide singers, legendary sea people who are said to charm storms with their singing. Morwenna has never believed the tales, but when she is left alone with the stranger, she realises this is no ordinary girl. Can the stories be true? Can the girl control the tides with nothing more than her voice? Her arrival brings danger of a different kind, and Morwenna must draw on all the courage she has in order to stop a conflict that could destroy her home...
