At a busy festival site on a warm spring night a baby lies alone in her pram her mother vanishing into the crowds. A year on Kim Gillespie's absence casts a long shadow as her friends and loved ones gather deep in the heart of South Australian wine country to welcome a new addition to the family. Joining the celebrations is federal investigator Aaron Falk. But as he soaks up life in the lush valley he begins to suspect this tight-knit group may be more fractured than it seems. Between Falk's closest friend a missing mother and a woman he's drawn to dark questions linger as long-ago truths begin to emerge.
