The Christmas Catalog

Her dream came true and ruined everything.
Emily Benoit left her small ranching community in Idaho to become the art director for a large New York City department store. In the process she broke her heart, as well as Devlin Camp's, the love of her life. Emily's back for Christmas and there are no tidings of comfort and joy from Devlin because he can't begin to forgive her. Besides, he got married. "Are you trying to break my heart?" "Yes," Devlin replies.
Emily knows too well what she gave up but how to get it back seems impossible.

Short story, sweet romance.
