Orabillis by Suzan Tisdale

Orabillis McCullum wore chainmail to her wedding — a stark warning to the groom that she wasn’t entering this marriage of her own accord. She would happily feed the former knight, Gavin MacKendrick’s entrails to the scavengers should he even think about anything other than a marriage in name only.
For Gavin MacKendrick, this predicament of his own making. Had he not gotten so bloody drunk and unknowingly bedded one of King Robert II’s daughters, he wouldn’t have lost his knighthood and now be staring into the eyes of a woman who infuriated him as much as enchanted him. But he’d rather chew stones and have his eyes skewered with a hot poker than admit his fascination with the beautiful female warrior.
By order of their King, these stubborn, independent, and strong-willed individuals must marry. But will they live long enough to get through the ceremony? Or will God actually show some mercy and step in to stop it?

Stranger things have happened.
