Reviewed by Linda:Five female coworkers walk into the Australian bushland on a corporate leadership retreat. Days later four emerge from the isolated wilderness battered and bruised. Agent Aaron Falk has a special reason for wanting to find the missing hiker; she is a whistleblower in a federal investigation. The plot has as many twists and turns as the hikers' trail, and the author's writing style makes this an enticingly creepy read.
