He’s the blueprint for perfection. She’s chaos in a cardigan.
Kieran Vance deals in structures, silence, and absolute control. As the lead architect at Sterling & Stone, he has no patience for disorder—and certainly no patience for the loud, vibrant interior designer who just became his partner on the biggest project of his career.
Cleo Moretti is a walking sensory overload. With a brain that runs on forty-seven open browser tabs and a penchant for breaking rules, she’s the exact opposite of Kieran’s color-coded existence. She knows he thinks she’s “too much.” She also knows his cold exterior is hiding something much more interesting.
When a high-stakes library project forces them into the same orbit, the friction isn’t just professional—it’s electric. Kieran finds his carefully built walls crumbling under the force of Cleo’s sunshine, and Cleo realizes that the quiet man in the corner might be the only one who can handle her storm.
But when office politics and a devastating fire threaten to burn their project to the ground, they have to decide if they’re just colleagues with benefits… or partners in every sense of the word.

Chapter One: Kieran
The fluorescent lights were trying to kill him.
Kieran Vance adjusted his noise-canceling headphones and stared at the blueprint on his screen, willing his brain to focus on load-bearing walls instead of the sensory assault happening beyond his glass office. The open-plan studio of Sterling & Stone Architects was designed to encourage collaboration. What it actually encouraged was a constant, low-grade migraine.
Someone in the bullpen laughed—a sharp, bright sound that cut through the ambient noise like a blade. He didn’t have to look up to know who it was.
Cleo Moretti.
He looked anyway…
