Kael Saunders, MI6 specialist operative and leather Daddy, has been living with Angel Button, his sub, for two years in a loving D/s relationship. Angel has been waiting for the time when he too can join MI6, knowing that his sniper skills make him a valuable asset to the organization. Kael loves to kill, it gives him an adrenalin rush, but Angel is certain his Daddy only eliminates those who pose a threat to national security, which is what Angel wants to do. Naive and idealistic, Angel wants to make the world a better place.
Angel's beliefs are sorely tested a few days later, leaving him unsure if he wants to be an MI6 agent after all. When Kael is given an assignment in Cornwall, he takes Angel with him so they can have a weekend away. Angel finds out about the mission and the target and is left wondering if his Daddy is really the hero Angel thinks he is, placing their relationship in jeopardy.
