I read the last book a while ago, so I’m not sure what parts of my feeling sort of “eh” about it were not remembering details from previous books and which were that, as an anxious person with Shit To Do, it wasn’t fun reading about a Lady Astronaut who is anxious and has Shit To Do. It’s about the second expedition to Mars, with a permanent habitat on the planet and an orbiting space station above it. A lot of stuff goes wrong but there are also secrets from a previous mission, secrets which may be endangering safety. A lot of “Why won’t these people TALK to each other?” thinking from me as I read this. Also, no shade to this terrific lady astronaut but in some ways--while she is a brilliant computer and thinky math person--she doesn’t always seem suited to lead an expedition.
