The Rogue's Ring. Treasure tales, #3

Heading out on his horse, Ghost, into the snowy Highlands of Scotland in January 1817 was not sane, but Bryce Ketteridge would never let down his friends. If a duke, an earl, and a former spy felt finding the owners of nobleman's rings was important, he would do his share. Coming across masked bandits, and shooting one, turned his life on end. What follows was not in his plans. The last thing Cat Douglas wished to do was steal coins from the handsome stranger she meets at a tavern.
When he later shoots her while she threatened a nobleman's coach, she suspected he had no idea it was her. Kidnapped boys, pirate threats, and murder propel them to save a boy named Blake. He was, after all, special to them both.
