Strange Grace is a standalone young adult novel from Tessa Gratton (also author of recently-released The Queens of Innis Lear) set in a town that knows no lasting hardship due to a pact with the devil. Illnesses pass in a night; wounds heal without infection; babies are born healthy with safe mothers; crops thrive under perfectly timed rains. However, the pact is upheld by the sacrifice of a young man every seven years to run the devil’s forest and see if he comes out victorious. The sacrifice of one allows all to live peacefully. None are forced—the trial is an honor.
Mairwen Grace is the only daughter of the town’s bloodline of witches, linked to the forest as her ancestors were before her, all the way back to the woman who made the original bargain. The witches form the liminal border between forest and town, life and death. However, when the bargain falls awry only three years after the last sacrifice, Mairwen and her closest companions, Arthur and Rhun, have a duty to determine the cause—whether they agree with the true nature of the bargain or not.
