by Peter Heller imagines a near-future world in which the wealthy have chosen to wall themselves off from the ever-multiplying Covid-19 variants. Kingfisher Lodge offers clients the exclusive opportunity to get away to a protected corner of the most pristine Colorado landscape, where the fishing is among the best in the world. Jack is a 25-year-old fishing guide hired by the lodge of escort Alison, a famous country singer, through the wilderness, but both of them become increasingly aware that the lodge may also have more sinister operations. A dark, twisty thriller, the book also revels in Heller’s descriptions of the landscape and muses about the cost of abusing it.
