Reluctantly throwing his ethics to the wind, Kasper submits himself to Logan, gambling his career, his future, and his heart on this intriguing man and the lifestyle he offers. But when Kasper's desires outpace Logan's, the young doctor is swept down into a whirlpool of sex and sadism that even Logan's love may not be enough to rescue him from.
