Twenty-nine-year-old Natasha Bell went for an evening jog, just like any other night - except now no one knows where she is. Not her sister, Abby - eighteen, eight months pregnant, and without a game plan. Not her childhood sweetheart, now ex-boyfriend, Greg, an introverted academic who could never bring himself to commit. Not her best friend Josie, a newlywed, born-again Christian, with whom Natasha recently had a falling out. And not detective Reuben Blake, who thought this case would be open 'n shut - a quick way to prove himself and move up the ranks. Missing person's statistics suggest Natasha's ex is the primary suspect, but what about the possibility of a stranger abduction? Or the possibility that Natasha left voluntarily or took her own life? What about Natasha's mother, who took off eighteen years before her daughter's disappearance? As days stretch into months and months stretch into years, the evidence that emerges seems only to complicate the picture more. Left explores the ways tragedy and secrecy erode and warp people's psyches and their bonds to one other. What secrets might Natasha have been keeping? - and, for that matter, her friends and family.
