An Unlikely Bride for the Billionaire (Harlequin Romance Book 4531)

A most unlikely match! 

Mia wants to keep her head down—not get distracted by handsome billionaire Dylan Fairweather! Asked to plan his sister's wedding, she can't say no to his other outrageous proposition: pose as Dylan's girlfriend so he can assess his future brother-in-law's intentions! 

Shy Mia doubts anyone would believe he's dating her…especially if they discovered the secret past she's worked so hard to leave behind. But as she grows closer to Dylan, Mia might just find she's more than worthy of this prince among men…
