J. FINN , AUTHOR OF THE WOMAN IN THE WINDOW When five female office workers are forced to go on a corporate retreat in the wilderness, they reluctantly pick up their backpacks and start walking down the muddy path. After all, this retreat is all about taking them out of their comfort zone. It's supposed to be a bonding experience--one designed to build trust. But it doesn't work out that way. One of the women never comes out of the woods. And each of her colleagues tells a slightly different story about what happened. Federal Police Agent Aaron Falk has a keen interest in the whereabouts of the missing hiker. Alice Russell is the whistleblower in his latest case--and, without her, there's no way he can win it. Now, in an investigation that takes him deep into isolated bushland, Falk discovers dark secrets lurking in the forest and a tangled web of loyalty, betrayal, and suspicion among the hikers. Still, a question remains: Is Falk on a search-and-rescue mission--or is this a case of murder? "COMPELLING...INTENSE PLOTTING."--ASSOCIATED PRESS "EXCEPTIONAL."-- THE NEW YORK TIMES BOOK REVIEW
