Exiles / Jane Harper.

A mother disappears from a busy festival on a warm spring night. Her baby lies alone in the pram, her mother's possessions surrounding her, waiting for a return which never comes. A year later, Kim Gillespie's absence still casts a long shadow as her friends and loved ones gather to welcome a new addition to the family. Joining the celebrations on a rare break from work is federal investigator Aaron Falk, who begins to suspect that all is not as it seems. As he looks into Kim's case, long-held secrets and resentments begin to come to the fore, secrets that show that her community is not as close as it appears. Falk will have to tread carefully if he is to expose the dark fractures at its heart, but sometimes it takes an outsider to get to the truth.
