The Sinner and the Liar by Alice Winters

Sin is a hard man caught in a crumbling city filled with crime. After losing the love of his life, Sin feels like he has nothing left to live for. Drifting through life, he takes on mercenary jobs by day and drinks away the memories of a happier time at night. Life has no color and little direction until he saves a gorgeous young man from a vicious attack. Sin doesn’t trust anything that’s too good to be true, but resisting the determined and seemingly innocent young man presents the first challenge Sin has had in ages. Eastyn brings brightness and humor to Sin’s previously dark and grim world, but there’s far more to Eastyn than he lets on.
Eastyn is trapped, a victim of circumstance, and he wants only to find a way out. He gambles everything to bend one dangerous man to his will in order to escape another. Falling in love was never part of that plan, but Sin gives him something he’s never had before: hope. With Sin, he suddenly has the power to become the person he has always wanted to be. He feels like he finally has a chance to escape, but how far is he willing to go to get what he wants?
In a fractured city poised between order and chaos, two men find in each other the last things either expect to find: friendship, acceptance, happiness, passion, and the chance at love stronger than the evil that surrounds them. But claiming and keeping that love will be the riskiest thing either of them will ever have to do. As a gang threatens to overtake the city, Sin is forced to decide if he will remain stuck in the past or open his heart to the man who has found his way into his life. Because Eastyn is unlike anyone he’s ever met before, and he might be the very thing needed to save Sin from himself.
