1126. Heulwen, daughter of Welsh Marcher baron Guyon FitzMiles, has grown up with her father's ward, Adam de Lacey. There has always been a spark between them, but when Heulwen marries Ralf le Chevalier, a devastated Adam absents himself on various diplomatic missions. When Ralf is killed, Heulwen's father considers a new marriage for her with his neighbour's son, Warrin de Mortimer. Adam, recently returned to England, is determined not to lose Heulwen a second time, which places them both in great danger, because Warrin de Mortimer is not a man to be crossed and the future of a country is at stake . . .
