Hunger in Velvet. The Devil's Gentlemen, #53

Simon thought he understood the darkness inside him. He was wrong. When Simon and Francis are summoned to the mysterious Velmont House, they discover an ancient mansion built around hunger itself-a supernatural force that feeds on blood, desire, fear, and devotion. At the center of the house stands Lord Valerian, a powerful and manipulative aristocrat who believes Francis carries the last blood of an ancient supernatural lineage.
As Francis's dormant abilities awaken, he begins hearing voices, commanding shadows, and sensing things that should not exist. The deeper they venture into Velmont House, the more Simon realizes that their invitation was never meant for both of them. It was meant for Francis. But the mansion has another connection to Simon. An enemy from his supernatural past has been waiting in the shadows, convinced that Francis's blood can restore the darkness Simon once fought to destroy.
Surrounded by betrayal, temptation, and supernatural hunger, Simon and Francis must confront the greatest danger of all: the possibility that their love can be turned against them. To survive, they must learn the difference between protection and control, desire and obsession, love and possession. Because the Hunger wants Francis. Valerian wants his power. And the darkness wants Simon. But neither man is willing to surrender the other.
In a world where blood remembers and desire can become a weapon, Simon and Francis must decide what they are willing to sacrifice-and what they will never give away.
