Mary's given up everything, including an unsatisfying marriage, to become a chef. But the career comes with a side dish: Kegan, her sexy but controlling new boss.

They're soon in a relationship, and in all-too-frequent arguments, and when it becomes clear they can't work together and be together Mary faces a dilemma: keep her dream job or her dream man?

Thirty-something Rhiannon is an obsessive planner and goal-setter, but somehow nothing she achieves ever seems good enough to her. Determined to lose forty pounds for her best friend's August wedding, Rhiannon flees her parents' house in a Christmas-day blizzard to avoid the temptation of all her favorite foods, but her car skids off the deserted road into a tree.

Unable to escape the car, with her leg trapped and bleeding and her cell phone out of reach, Rhiannon is at first certain she'll be rescued and writes notes to her friends and family to pass the time. As the weather cools and her condition deteriorates, though, she recognizes the possibility that her life might be over. Interspersed with increasingly desperate escape attempts, her letters become deeper and more heart-felt as she comes to see what really matters in life.
