The Best Man’s Surprise Baby by Holly Rayner

He hates weddings. She believes in forever.
Six weeks, one impossible task…and one night that changes everything.

Workaholic billionaire Theo Davenport wants nothing to do with romance, but when his younger brother asks him to help pull off a whirlwind Houston wedding, Theo agrees, grudgingly. Enter Harper Martin: bubbly, big-hearted, and determined to make the day unforgettable. As maid of honor and aspiring wedding planner, she’s everything Theo isn’t… and exactly who he’s forced to work with.
Clashing visions spark constant friction, his money-versus-her-meaning approach turning enemies into something far more dangerous. When a forced overnight stay strips away Theo’s armor, one unforgettable mistake blurs the line between business and desire. They agree to walk away. No feelings. No future.

Until Harper discovers she’s pregnant.
As the wedding day arrives and secrets unravel, Theo is forced to confront the very thing he’s spent his life avoiding: love, family, and the chance to be better than his past.
