After a disastrous blind date, Darcy Lowell is desperate to stop her well-meaning brother from playing matchmaker ever again. So she fibs and says her latest set up was a success. Darcy doesn't expect her lie to bite her in the ass. Elle Jones, one of the astrologers behind the popular Twitter account, Oh My Stars, dreams of finding her soul mate. But she knows it is most assuredly not Darcy, a no-nonsense stick-in-the-mud, who is way too analytical, punctual, and skeptical for someone as free-spirited as Elle. When Darcy's brother, and Elle's new business partner, expresses how happy he is that they hit it off, Elle is baffled. Was Darcy on the same date? When Darcy begs Elle to play along, she agrees to pretend they're dating to save face. But with a few conditions: Darcy must help Elle navigate her own overbearing family during the holidays and their arrangement expires on New Year's Eve. The last thing they expect is to develop real feelings during a fake relationship.
