"Marry me."They were the last words I expected to say to my fake fiance, but I'm the kind of guy who doesn't back down from a challenge. Pretend I'm engaged to my gorgeous and talented business partner to secure a business deal?No problem. Agree to a no-touch rule even though she's been driving me wild since I met her?Challenge accepted.Resist grinning like a damn fool every time that same big-hearted, sunshine-y woman laughs with my little daughter?Done. So, yeah, when my fake fiance's vindictive business rival threatens to expose our make-believe romance, I can handle that too. I'll prove our engagement isn't fake - by marrying her for real. A marriage with an expiration date at the end of the year.But that's when I run smack dab into the biggest challenge ever - not falling madly in love with my wife.
