It's summer 1270, and England is as weary as its aging king, Henry III. The Simon de Montfort rebellion is over, and in the small priory of Tyndall on the remote East Anglian coast, the monks and nuns of the Order of Fontevraud long to return to their tranquil routine. But then the young, inexperienced Eleanor of Wynethorpe is appointed their new prioress. It's a political move and not popular.
The day after she takes up her office, a brutally murdered monk is found in the cloister gardens. Then Brother Thomas arrives. Sent to investigate the Order's shaky finances, the young priest is also paying the price for a crime that could see him burn. As Thomas battles to accept his new life, Eleanor, struggling to gain the respect of her terrified and resentful flock, must cope with violence, lust, and greed to find a vicious killer.
