Last year, the big bio book was Barbra’s.  This year, Cher will be hitting the shelves.  Strike that – this year and next year.  Rather than release one giant book like Babs, Cher is breaking up her story.  HarperCollins just announced that Cher: The Memoir, Part One will be released on November 19^th.  This volume will cover the early days up through her divorce from Sonny Bono – which she describes as “the highly complicated relationship that made them world-famous, but eventually drove them apart.”  Part Two is slated to come out late next year.
