It is spring, in the year 1297. Recently widowed Joanna of Acre, loving daughter of Edward I, is pleased at her father's unexpected visit. But Edward has heard a rumour of an inappropriate friendship between Joanna, still officially in widow's weeds, and penniless commoner Ralph Monthermer. Edward, believing he has proof of a clandestine affair, immures Joanna in a nunnery and imprisons Ralph within Bristol Castle. Henry Trokelowe, Edward's clerk, stops him killing Ralph, who is allowed to live while the cold, almost passionless Henry investigates. Ralph and Joanna's only chance of survival now lies in Henry's hands, but how can a confirmed bachelor even begin to understand the all-consuming passion binding them? Immersed in the colours and drama of Medieval life, this richly evocative novel combines fact and fiction to tell one of history's greatest but most secret love affairs.
