With one of his lovers imprisoned in the Underworld, Mac has no choice except to go where most angels fear to tread.

With Tristan imprisoned in the Underworld, the ménage is broken. Angels are forbidden to enter the demonic domain and while Mac has been breaking rules in recent months, he doesn't have the power to enter the Underworld.

Alastor is still unsure about his position in the relationship following recent revelations, but he cannot walk away when he is the only real link between his two lovers. Splitting his time between Mac and Tristan, he hopes they can soon find a way to reunite the two men in his life.

As time moves on, Alastor realizes he is struggling to satisfy Tristan's thirst for sex. His lover needs more than he can give him and craves Mac in his bed.

Mac still believes he can complete his mission to save his two lovers, but with one of them out of his reach, it is going to be far from easy.

During their time together they have made plenty of enemies, including one who would seek to separate them forever, even if it means biding his time until Alastor and Tristan are at their most vulnerable, when even the love of an angel can't save them.
