I have become an Andy Weir fan, on the basis of his earlier books, *The Martian* and *Artemis,* and I didn't know what to expect with his latest book. The title didn't particularly "grab" me. But immediately upon opening it, I was hooked. The protagonist, who tells the story in the first person, wakes up in an unknown environment, with only two corpses and a set of mechanical arms for company, and he has no idea where he is, or even his name and identity. So the story begins with the hero's first experiments to uncover his whereabouts, and short flashbacks as he begins to remember bits and pieces of his past history. That may sound a bit off-putting - it shouldn't be! Weir is a rivetting writer, and he includes much dry humor, and the book is not just a solo journey for long - I will say no more! MOST highly recommended!
