The Conquest — Julia Templeton

Two men fought for her.
Only one would taste victory.

HER BODY WAS PROMISED TO ONE MAN.
Rhiannon MacKay, daughter of the wealthy laird of Clan MacKay, always knew she would one day be married to someone of her father's choosing. However, when he offers her hand and dowry to the older Norman baron Lord Malgor in exchange for the Lord's services to the king, it is nothing like she had imagined. Now she must spend her life with a man who could never satisfy the needs of someone so ripe and willing.

SHE SURRENDERED IT TO ANOTHER.
When handsome Adelstan Cawdor is hired to escort Rhiannon to her betrothed, one look at her and he is smitten. He despises having to deliver this beauty to a rival. What's more, Rhiannon doesn't want to go. She yearns to be rescued -- and taken by a man like Adelstan, regardless of betraying a formidable foe like the baron. But when Rhiannon's life is threatened, Adelstan's prepared to do anything to win his lovely prize, and save her from the terrible consequences of another man's vengeance.
