Cess works caring for the chickens at Montacute House but on her thirteenth birthday everything changes. She finds a precious locket hidden in the chicken coop and is convinced someone has placed it there for her to find. But the day is overshadowed by fear as a boy's body is found by the river, and then when William disappears, Cess is accused by the villagers of bewitching her best friend.

Cess is determined to find William and prove the villagers wrong, but is soon embroiled in a plot that threatens her world and forces Cess to draw on powers she never knew she possessed, powers that will place her life in danger if they are discovered by the villagers.

Witchcraft, politics and religious ambition combine in this gripping and wonderfully realised novel set in the Somerset of the 1500s.
