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 elsewhere, to Ralf le Chevalier, a devastated Adam absents himself on various diplomatic missions for King Henry I.
When Ralf is killed in a skirmish, Heulwen's father considers a new marriage for her with his neighbour's son, Warrin de Mortimer. Adam, recently returned to England, has good reason to loathe Warrin and is determined not to lose Heulwen a second time. But Heulwen is torn between her duty to her father and the pull of her heart. Adam is no longer the awkward boy she remembers, but a man who stirs every fibre of her being - 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 . . .
