I found this sitting in a pile of free books outside the local bakery and, having heard of it for years, decided to give it a go. It’s fascinating and entirely not what I expected. After a great start the book slows to a crawl as the business of life on Mars takes shape. There are a few welcome time jumps and then an absolutely blistering final third. I’ll have to read the sequels I guess.
