After an introductory chapter, we start by looking at early ideas and myths about the sky pattern referred to most often now as the Milky Way, long before it was realised that this was our galaxy. We are then taken through the Milky Way's formation (and along with that information on stars and other components that go together to make up a galaxy) and McTier goes on to do everything from pull apart Star Trek's dodgy navigational coordinates to what remain mysteries to current science. (Unusually for a simplifying popular science book, we do hear a bit about alternatives to dark matter, though McTier does dismiss MOND using arguments that are weaker than those that could be used to dismiss dark matter particles.)
So far, so good. One thing that it is essential to cover is the subtitle. The second word is not 'biography', but 'autobiography'. The book is written from the viewpoint of the Milky Way as if it were a conscious entity. I must applaud this in the sense that it's a different way of looking at astronomy/astrophysics. Any book of this sort benefits from taking a different approach, because mostly it will have been done before. But.
For me, personally, the approach was one where I really had to suppress the cringe reflex. The first chapter begins 'Take a look around you, human. What do you see?.. Everything you've ever seen or touched is part of me. Yes, even you, you vain, filthy animal.' I don't know why, but this does feel ever so slightly condescending for an adult audience. And it's a bit odd - given we are effectively part of the Milky Way in terms of our constituents, why would it call us filthy? But then, on the whole, galaxies don't call people anything.
Anthropomorphising is, of course, an age-old technique. I used to watch a TV show called Tales of the Riverbank when I was four that featured, for instance, a talking guinea pig and loved it. But while I accept the originality of the approach as popular science, I still had to fight down my aversion as an adult. Perhaps the main potential problem in non-fiction is where to draw the line between the fiction of the talking galaxy and the reality of the science. For example, McTier's galaxy is quite boastful. It comments 'I am the greatest galaxy who has ever lived.' But the Milky Way is neither the biggest galaxy nor does it contain the most stars, making this a dubious boast at best.
As long as I had this tendency under control, there was plenty to enjoy here - and that's why I'm giving the book four stars. But I can't ignore it, nor do I think that it will work for every reader. But if you won't be put off by the approach, this is an excellent book on an essential topic.
