The most treacherous terrain is found within

Ten years ago, sisters Olivia and Melanie Greene were on a hiking trip when their parents were in a fatal car accident. They haven't seen each other since the

funeral. Olivia coped with the loss by plunging herself into law school, work, and a materialist view of the world—what you see is what you get, and that's all you

get. Melanie dropped out of college and developed an online life coaching business around her DIY spirituality—a little of this, a little of that, whatever makes you happy.

Now, at Melanie's insistence (and against Olivia's better judgment), they are embarking on a hike in the Porcupine Mountains of Michigan's Upper Peninsula.

In this remote wilderness they'll face their deepest fears, question their most dearly held beliefs, and begin to see that perhaps the best way to move forward is the one way they had never considered.
