These Darn Heels — Julie Stone

But as her thirtieth birthday draws near, the life Alex loves threatens to unravel. Faced with the possibility of losing her shop, Alex is forced to take drastic measures, including crashing a bridal fair, making nice with her socialite mother, and faking a romance with Peter Gibson, a handsome doctor.

As the plot to save Correspondence draws them together, Peter and Alex find they have more in common than just their romantic charade. For Alex, who has never believed in love, the prospect of finding it is enough to send her running--if only she could run in heels.
