God of Fury (deluxe edition) (Legacy of Gods #5) by Rina Kent

I'm slowly sinking.

Brandon King never thought he was attracted to men. To be honest, he'd never been that attracted to anyone. But that was before he slammed directly into Nikolai Sokolov, a mafia heir known for being a notorious bastard and violent monster.

Once Nikolai has his sights set on Brandon, he's haunted by him. He can't seem to let him go. A man who is so unlike him in every way: a quiet artist, golden boy, and his enemy's twin brother.

Brandon can't seem to get rid of Nikolai―he's everywhere. And his being everywhere throws a wrench into Brandon's carefully controlled life. Nikolai is desperate to break that control down.

While Brandon worries about Nikolai's role in his life and his slowly disintegrating control, he learns that being wanted by a beautiful nightmare is much worse.
