God of Fury Book by Rina Kent

Brandon King is the golden twin―an elite student, gifted artist, and son of a criminal dynasty he wants no part of. He thrives on discipline, silence, and emotional distance.

Until Nikolai Sokolov appears.

A mafia heir with blood on his hands and madness in his gaze, Nikolai is everything Brandon isn't: violent, unfiltered, and magnetic. When Nikolai sets his sights on him, Brandon's carefully curated world begins to unravel. Attraction turns to fixation. Boundaries dissolve. The more Brandon resists, the deeper Nikolai pulls him under.

And the scariest part? Brandon doesn't want to escape.
