Not quite up to the standards of [b: The Martian|18007564|The Martian|Andy Weir|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1413706054l/18007564.SY75.jpg|21825181] and [b: Project Hail Mary|54493401|Project Hail Mary|Andy Weir|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1597695864l/54493401.SY75.jpg|79106958] (though, frankly, three books at that level in this amount of time would be downright suspicious). The tone is a little less appealing and the plotting is overly tidy at times, but Weir keeps it enjoyable and briskly paced. He takes a somewhat sophomoric approach to writing a female narrator, though; hopefully not something he'll attempt again soon.
