Founded over four hundred years ago, Sanctus Infinitus Redemptio is a private and very elite society where dominance and submission are revered. Steeped in tradition and excellence, every Dominant and every submissive, and their pairing, are selected with great care. When Hunter Vargo is brought into the Sanctus, his need for strict dominance sees him paired with the wrong Master. But only a short time later, mistreated and his trust broken, he's recalled, his collar removed. The Grand Master knows it will take a special kind of Dominant to restore the sub's faith and trust. Sig Bruckner's world is perfect. He has a great job, he has high standing within the Sanctus, and he has Levin, the very best submissive. When he's asked to take on a second sub, a young man with issues and a rule not to touch him, Sig's world is turned upside down. When his dominance, his patience, and self-control are tested, and when Sig's relationships with both subs are pushed past his limits, everything begins to unravel. Yet Sig knows every good Dom learns from their subs, and he's no exception. He might not be able to fix everything on his own, but perhaps the three of them together can.
