Yorkshire is in the grip of a heatwave, and Thruscross Reservoir has dried up to reveal the remains of the drowned village of Thores-Cross beneath.
Playing in the mud which coats the valley floor, four-year-old Clare Wainwright finds an old inkpot, and she can’t wait to show it to her best friend, Louise. But when Louise’s mother Emma sees it, her reaction is shocking, and both families are plunged into their worst nightmares.
Emma knows what the inkpot portends: Jennet has woken.
Now she wants the children.
Jennet will have your heart and your fear in equal measure. Through Jennet, we find how cruelty can drive even the most ordinary people to hatred and, in Jennet's case, evil.
