"When it comes to living life to the fullest, it ain't nobody's business how one goes about it.At the age of forty, artist-turned-librarian Eva Hutchinson isn't looking for a change. But on a hot Friday the 13th in June, Hutch, her husband of ten years, picks up his suitcase and walks into the night searching for the "joy" that he feels is missing from their marriage. Suddenly, playing by the old rules doesn't make much sense to a not-quite-young sister whose stable world has turned upside down.Now Eva is alone with an empty heart in a big, empty house. Hutch fears he is falling in love with the neglected wife of his wealthy, philandering best friend. Charley, Eva's law school-bound daughter, wants to chuck it all and become a stand-up comedian -- while Steven, Hutch's son, harbors a secret that will rock his father's world. And into the mix strolls Isaiah Lonesome, a handsome hunk of a twenty-eight-year-old jazz musician who will teach Eva to play some lusty new riffs on love's oldest song.
