A compulsively readable survival thriller ala Deliverance and The Descent that is begging to be adapted into a show or film. It features a group of friends in their late 30s, all women, who don't regularly see one another in their day to day lives but who take periodic, adventurous vacations away from it all. On this vacation their fearless leader, Pia, has arranged for them to raft a river in Maine, one that is virtually "undiscovered," according to their young, male guide. Read "undiscovered" as in the middle of nowhere, no cell phone coverage, and no help nearby. You see where this is going.
Disaster strikes during the trip, and the group is forced to make tough decisions and survive a dangerous situation that only gets more dangerous. The strain heightens tensions and reveals cracks in the group, and everyone loses their shit in a way specific to each character. Our narrator is Winifred (Win or Wini), clearly the least brave of her friends, a woman who's recently lost her husband (divorce/separation) and younger, deaf brother. She's lonely, at sea in her life but without the impetus to make changes and be happier.
All the women bring their own baggage, but it's Pia's need to be "off the grid," be authentic, whatever that means, that brings them to the river. Besides Win's relatable narration, the adventure, and some very cool descriptions of their environment, the book's refusal to say, simply, that nature is better and civilization is corrupt is a favorite aspect of the story.
