"Waiting to Exhale" garnered national attention and a rabid following for its author, Terry McMillan, in 1992; it became a film in 1995. The following year, "How Stella Got Her Groove Back" was also a smash hit that told the tale of a woman who takes a trip to Jamaica and meets a man half her age. "Getting to Happy" (Viking) is the long-awaited sequel to "Exhale." It reunites its predecessor's characters – now in their 50s – who live in Phoenix and are struggling with their midlife crises.
