This is the third Kinley MacGregor book I've ever read, and while I liked the first two (Master of Desire and Claiming The Highlander) this was without a doubt my absolute favorite. MacGregor's books are a skillful blend of humor and eroticism, thrown into a historical setting and some really believable characters.
Born In Sin is the story of how Lord Sin, King Henry's legendary assasin and most trusted advisor is forced to marry the daughter of a Scottish Laird to ensure peace is kept in the Highlands. Given Sin's scarred and tormented past, he is determined not to be owned in any way, shape or form, even as the spirited Caledonia MacNeely welcomes him with open arms - initially in the name of peace. Given that in Claiming The Highlander Sin had said he'd rather do pretty much anything rather than lie down with a Scotswoman, Callie does a pretty good job of penetrating through his supposedly 'invincible' defenses by offering him the one thing he's never known in his life - love - and claiming him for her own. This is a thoroughly enjoyable book, and Lord Sin has to be one of the hottest, *baddest* bad boys ever. Well worth a read.
