SINN: Lust: Level -2 by Felix Arman

Two weeks ago, Lucas Wagner walked through a brass door in Berlin and discovered SINN — a secret club built on ten levels that descend like Dante's circles. In the soft blue light of Level -1, he learned that his body was allowed to feel.

Now he has been invited deeper. Level -2 is called Lust, and its Gatekeeper is a barefoot Italian named Matteo, who believes appetite is a gift. Under Matteo's hands, Lucas learns that pleasure can be layered on pleasure — wax and ice, feathers and silk, heat and cold — until the body stops naming what it feels and simply feels. For the first time, Lucas understands what it means to want more than he can bear, and to choose not to stop.

But the club is not the only thing pulling him back. There is Leon, the bartender behind the bar — dark-eyed, too-knowing, and watching Lucas more closely than a bartender should. When Lucas catches a glimpse of the solid black rectangle tattooed over Leon's heart, he knows he has seen something buried. He does not know what it hides. He only knows he cannot stop thinking about it.

Lust is the second volume of the SINN series, a slow-burn MM romance in which each book descends one level further — into the club, into the mystery of the sealed black door at the bottom, and into the space between two men who keep finding each other on the wrong side of the bar.
