Kelly Wilder becomes recently widowed from a much older wealthy man with whom she spent her married life, as she says, 'pretending to be a whole lot more conservative and stupid and nicer than I really am.' Now, with too much time and money on her hands, Kelly has absolutely no idea what happens next. So on a whim she signs up for a ballroom dancing class, and begins to rebuild her life with the help of friends old and new: Nik, a young Russian dance teacher who sees the artistic potential she left behind; Carolina, a woman in hospice, anxious to experience a whole lifetime in a few months; and Elyse, Kelly's girlhood best friend who knows all of her past secrets - including the truth about the man who long ago broke Kelly's heart.
