The year is 1980. Las Vegas has grown from a crude desert wasteland filled with bawdy miners and bingo parlors into a showplace of dazzling casinos - a gambler's paradise. Fanny Thornton has recently married Sallie's son, Simon, but theirs is not a happy union. Simon is a jealous, domineering man whose suspicions and increasing paranoia about his brother - Fanny's ex-husband Ash Thornton - have estranged Fanny from her four children. But now Ash is ill, possibly dying. Babylon, his life's achievement - and Vegas's most magnificent casino - is in danger of falling into the wrong hands. It is Fanny who reluctantly steps in to take over Babylon...Fanny who vows to make her family whole again even as Simon tries to sabotage her at every turn. But when another man offers her the chance for a new beginning, it is a gamble Fanny is determined to take.
