Hard book to review. A novel and yet it reads more like a memoir. It is about everything and nothing. We share the inner and outer lives of 6 astronauts/cosmonauts as they orbit the planet in an international space station. The descriptions of the earth from space and the 16 ascending/descending orbits that make up a day and a night are beautiful and enigmatic and otherworldly and unimaginable and this novel is unlike any other I have read.5⭐️
