Under A Falling Star by Jae

Falling stars are supposed to be a lucky sign, but not for Austen. Her new job as a secretary in an international games company isn't off to a good start. Her first assignment-decorating the Christmas tree in the lobby-results in a trip to the ER after Dee, the company's second-in-command, gets hit by the star-shaped tree topper. Dee blames her instant attraction to Austen on her head wound, not the magic of the falling star. She's determined not to act on it, especially since Austen has no idea that Dee is practically her boss.
