"The River" by Peter Heller. My rating: 5 out of 5 stars. Published in 2019.
Book description: A masterful tale of wilderness survival in the vein of Into the Wild and The Call of the Wild. It is the story of two college friends on a wilderness canoe trip--a gripping tale of a friendship tested by fire, whitewater, starvation, and brutality.
This book is fiction that feels and reads like real life. I got caught up in every word and was transported by the writing.
