Theo Ashford is a twenty-eight-year-old perfectionist who likes his life precisely measured and carefully planned. As the lead architect on a forty-million-dollar mixed-use tower, he can't afford any mistakes. He certainly can't afford the distraction of the project's lead contractor. Cal is everything Theo isn't: massive, rugged, and entirely unshaken by the chaos of the construction site. He's a man who works with his hands, grounded and immovable, and he sees right through Theo's tailored Tom Ford suits and carefully constructed armor. When long hours on the site turn into late nights over the drafting table, the professional tension between them threatens to combust. Theo is used to controlling every variable, but Cal is dismantling his defenses beam by beam. They are exact opposites, but as the walls come down, they might just discover they are exactly what the other needs to stand tall. Built to Last is a high-heat, opposites-attract MM contemporary romance featuring a tightly wound architect, a steady and protective contractor, and a guaranteed happily-ever-after.
