The Wedding1992
by Emma Darcy
From back of book:
It was time out of time
First, Tessa discovered her fiance in bed with another woman. Then she arrived at work to discover she'd been assigned to go on a three-day conference with the managing director.
It would be a miracle if she didn't melt into a heap at his feet. If ever there was a man made for female fantasies, Blaize Callagan was it!
And if ever there was a time Tessa needed to indulge in fantasy, this was the time.
