Thus begins an adventure in which Jazz has to summon all of her formidable intellect, cunning, and resources, form expedient alliances with unlikely parties, solve a technological mystery, balance honour with being a outlaw, and discover the economic foundation of Artemis, which is nothing like it appears from the surface. All of this is set in a richly textured and believable world which we learn about as the story unfolds: Weir is a master of “show, don't tell”. And it isn't just a page-turning thriller (although that it most certainly is); it's also funny, and in the right places and amount. This is where I'd usually mention technical goofs and quibbles. I'll not do that because I didn't find any. The only thing I'm not sure about is Artemis' using a pure oxygen atmosphere at 20% of Earth sea-level pressure. This works for short- and moderate-duration space missions, and was used in the U.S. Mercury, Gemini, and Apollo missions. For exposure to pure oxygen longer than two weeks, a phenomenon called absorption atelectasis can develop, which is the collapse of the alveoli in the lungs due to complete absorption of the oxygen gas (see this NASA report [PDF]). The presence of a biologically inert gas such as nitrogen, helium, argon, or neon will keep the alveoli inflated and prevent this phenomenon. The U.S. Skylab missions used an atmosphere of 72% oxygen and 28% nitrogen to avoid this risk, and the Soviet Salyut and Mir space stations used a mix of nitrogen and oxygen with between 21% and 40% oxygen. The Space Shuttle and International Space Station use sea-level atmospheric pressure with 21% oxygen and the balance nitrogen. The effects of reduced pressure on the boiling point of water and the fire hazard of pure oxygen even at reduced pressure are accurately described, but I'm not sure the physiological effects of a pure oxygen atmosphere for long-term habitation have been worked through. Nitpicking aside, this is a techno-thriller which is also an engaging human story, set in a perfectly plausible and believable future where not only the technology but the economics and social dynamics work. We may just be welcoming another grand master to the pantheon.“I'm sorry but this isn't my thing. You'll have to find someone else.”
“I'll offer you a million slugs.”
“Deal.”
