The river / Peter Heller.

Originally published: 2019.

Wynn and Jack have been best friends since their first day of college, brought together by their shared love of literature and the great outdoors. When they decide to take time off university and canoe down the Maskwa River in northern Canada, they anticipate the ultimate wilderness experience. No phones. No fellow travellers. No way of going back. But as a raging wildfire starts to make its way towards them, their idyllic expedition becomes a desperate race for survival. And when a man suddenly appears, claiming his wife has vanished, the fight against nature's destructive power becomes entangled with a much deadlier game of cat and mouse. Because the only thing more dangerous than a burning forest is a man's thirst for revenge.
