Force of Nature

FIVE WOMEN GO ON A HIKE.
ONLY FOUR RETURN.

When five colleagues are forced to go on a corporate retreat in the wilderness, they reluctantly pick up their backpacks and start walking down the nuddy path. After all, this retreat is supposed to take the office workers out of their air-conditioned comfort zone. It's supposed to be abonding experience. It's supposed to be a bonding experience. It's supposed to build trust.
But it doesn't work out that way.
One of the women doesn't come out of the woods. And each of her companions tellsa slightly different story about what happened.
Federal Agent Aaron Falk has a keen interest in the whereabouts of the missing hiker. Alice Russell is the whistleblower in his latest case--and in just a matter of weeks, she was supposed to help him bring down both the company she works for and the people she works with.
In an investigation that takes him deep into isolated bushland, Falk discovers secrets lurking in the mountains and a tangled web of personal friendship, suspicion, and betrayal among the hikers. But did that lead to murder?
