New York Times bestselling author Monica Murphy wraps up her sexy Billionaire Bachelors Club series with a wedding to remember. But this time, they're not bachelors anymore, and the groom … is one of them.

It's Gage and Marina's wedding day, but wedded bliss seems a long way off: Ivy's just gone into labor, Marina's missing her matron of honor, and Bryn's giving Matt the silent treatment.

It's up to Archer, Gage, and Matt to make sure this day goes off without a hitch. But between brides and babies, there's the not-so-little issue of the million-dollar bet to attend to. If only they can figure out who won … and who's paying up. Is everyone a winner? Or will someone leave broke—and brokenhearted?
