A City on Mars
Posted April 17, 2023 at 10:11 am

Good morning, friends. Today we launch a book that is the culmination of two people’s efforts over 5 years. The definitive treatment of space settlement - the science, history, law, and politics. It’s called A City on Mars.

You can get specific info on What I really just want to say here is, first, thank you all tremendously. Having a successful comic over these years has meant a lot of time could be devoted to in depth study of subjects that rarely get that kind of treatment.

What I also want to say is that I hope we’ve written my favorite kind of popular science book - one of those books where every chapter tells you something you’ve never heard about, and which adds up to a big picture. A book full of stories and ideas that you won’t hear anywhere else. Also jokes! And drawings!

Although we’re happy any time you buy, preorders right now, today, really help. In the modern publishing world, having a lot of buys early on gives us more power later when it’s time to ask for shelf space and media appearances. The book will cost the same whether you buy it now or a year from now, but getting it soon helps us tremendously.

Thanks again everyone. It has long been a dream of mine to work on a popular science book that isn’t just fun, but which tries to address a serious question in a way that hasn’t been done before. I believe we’ve done that here, and much of our ability to do that is thanks to all of you.

With gratitude,


Because a lot of people have been asking lately: if you do not want to buy on Amazon, there are lots of options. Buying on amazon *does* help us because it improves our ranking, but buying from Barnes & Noble is also great. If you want to avoid a big corporation, we recommend getting in touch with your favorite local shop, or with one of the awesome indie stores like Powell’s or The Strand.
