Yes, Sir; No, Sir Two highland lads from rival clans find themselves sharing a small island where they are grazing cattle for the summer. Hostilities quickly decline into tolerance, and eventually, over the summer, a firm and strong and loving relationship. On leaving the island, each lad goes back to his own clan, and the story follows the life of both men in their parallel and separate worlds. It follows their loves and their adventures until, years later, fate brings their paths together—no longer boys but now powerful members of their respective clans.
