At the King's Pleasure by JL Gorman

The daunting Lord Montclaire is outraged when he returns from the crusades to discover that the scheming King Richard the Lionheart has bestowed his lands upon a young heiress. The astute Diana is not impressed either, realising the danger of her new inheritance, especially when the chivalrous and lethal Montclaire seeks her out and discovers he wants her – and not only for his estates. Can she trust him as the king's entourage are swept up in the pursuit of war against the French?
