Aiden St. James is everything a CEO should be: polished, reserved, and untouchably professional. He never raises his voice, ruffles his perfect suit, and definitely never gets his hands dirty. But Elena Moralas knows better. As his whip-smart, shamelessly bold executive assistant, she’s made it her personal mission to crack his icy composure. However, it seems he has plans of his own, in the form of a sleek black box. Silk ropes. A leather-bound manual. And a note with her name written in his precise, deliberate writing. 

Turns out Aiden has a secret, a talent for rope play that turns his control into art, and a quiet dominance that hits every one of Elena’s buttons. Soon they’re playing a dangerous game, where each encounter is more daring than the last. But someone’s watching, and when anonymous threats start to appear, Elana and Aiden have to decide…

Do they untie the knots between them before they’re exposed… or tighten them until they can’t let go?
