Guarded by the Warrior. The Conquered Bride Series

A lady in need of protection... Suffering through a short marriage to an enemy of Scotland, Lady Emilia MacCulloch manages to escape just before her husband dies. But the Ross Clan will stop at nothing to get her back, for she plays a big part in their plans to thwart Robert the Bruce. She fears not only for her life, but for her family who will be labeled traitors. Placed by her king as a governess in the household of a devastatingly handsome warrior, Emilia finds herself drawn to the man when she had previously sworn off love altogether.
His passion, charisma, loyalty, and strength shake the very foundation she's built around her heart. A warrior in need of saving... Ian Matheson has spent his entire life trying to prove himself. To belong. When his father passes away and his mother takes her vows at a nearby abbey, he is suddenly left in a position he was wholly unprepared for. And then his father's dozen illegitimate children arrive on his doorstep in need of a father figure of their own.
They are adorable and reckless, and he's certain they'll drive him mad. Just when he thinks he might actually need to find a wife to help him, Lady Emilia is presented to him by the king. She needs his protection and he needs her help with the bairns. Ian is tempted by her angelic face, her fiery tongue, and the secrets that surround her. He must resist the growing desire that's laying claim within him.
He must prove to his clan that he is a worthy leader. But maybe, just maybe, he can have the respect of his people and Emilia, too.
