The Ward of Falkroy by Loki Renard

At eighteen years of age, Kelsie of Kinleigh has nothing but a short and miserable life of poverty to look forward to. She is a peasant looked down on by the other peasants, clothed in rags and fed from the scraps of pigs.
Kelsie’s fortunes undergo a marked change when she is plucked from her little village by the sorceress Lady Victoria Varys. Victoria has plans for the innocent peasant girl – plans which are abruptly interrupted when an assassin named Leo Falkroy tracks them down with the intention of arresting Lady Victoria for her crimes against royalty.
He is a man like no man Kelsie has ever known before. With a sword in his hand, he is second to none. He leads a life of rigorous discipline, leaving nothing to chance and ensuring that everything in his domain is firmly under control. He is educated, dominant and deadly – just as well, because Lady Varys is about to lead all of them into very big trouble.
