This novel is set about seventy years in our future, by which time we have several established colonies on the moon, regularly mine the asteroid belt, and Hilton maintains a hotel in Earth's orbit. This era gives the authors easy humor targets, such as the tale of a battle during the Second Canadian War where a US base was ambushed and should have been lost, but the Canuck soldiers didn't secure the showers and were overtaken by a bunch of naked GIs. Sadly these moments are the best parts of the book; the plot was middling at best and the characters one-dimensional—which takes some doing as much of the time they are themselves playing other roles in a giant LARP. Uneven but entertaining, this is a good afternoon read but not one that is going to provoke a lot of thought.
Botanica was a medium-sized crater, recently sealed to hold an atmosphere of oxygen baked from lunar rock and nitrogen imported from the Aeros asteroid.
