I didn’t care for it. It takes place on the first moon city that is a tourist attraction for wealthy earth folks. 26 year old Jazz is a porter (and smuggler) in the city and gets caught up in a murder and action-packed adventures for control of the city. I thought the Jazz character was too similar to Mark Watney from The Martian except in a female form – smart talking and handy with tools. The plot was passable but was dragged down with long winded passages about welding, chemical reactions, and other such scientific mumbo-jumbo that Weir could stick in there, plus the smart-ass comments from Jazz & other got old . Duct Tape is used, and there is lots of welding… lots. Call it a sophomore slump (Similar to how I felt about Ernest Clines’ second book – Armada).
