Another brilliant sci-fi book with emotional and psychological depth. Set on a base on Mars, it's a mysterious thriller with untrustworthy AI's, conspiracies, personal trauma and complex characters. We get a lot of the main character's thought process, it's very intimate. The main character is a geologist and a painter, and she struggles with her decision to leave behind her husband and her daughter on Earth to pursue a one-in-a-lifetime job opportunity. Weird things happen at the base and from the first chapter I was totally into the mystery, wanting to know what happened. It features excellent mental health representation, it's raw and real. I had tears in my eyes when I finished it.
