He calculated ever angle except the one straight to her heart.
 
When perfectionist event planner Claire Ashford abandons her wedding for a rainy truck cab confession with her almost-brother-in-law Ryan Jacobs, she thinks it's just one night of weakness. But a year later, Claire's buying a crumbling lakeside boathouse, and she needs Ryan's engineering expertise to transform it into her dream venue.
 
Ryan has always understood equations: forces, variables, structural integrity. He's spent his life solving problems. But Claire? She's the one variable he can't quite figure out. Especially when chemistry was never their problem.
 
Working together on nights and weekends, Claire and Ryan discover that some foundations are worth fixing. Twice.
