When Louisa Clark—Lou, as she's known—unexpectedly loses her waitressing job she must scramble to replace the income that her tight-knit family depends upon. Desperation drives her to take a job as a caregiver to Will Traynor, a man who used to be a wealthy banker with an adventurous soul, living life to the very fullest, but for whom those days are in the past. After a tragic accident, Will lost the desire to live and now keeps everyone at a distance with his caustic, overbearing attitude. But unlike his family, Lou refuses to tiptoe around him or cater to his moods. In fact, her sparkling personality and easy nature are hard for even Will to ignore, and soon enough each becomes exactly what the other needs.
