SSI (the Space Studies Institute) has just announced that, for a few days, anyone can get the Kindle version of The High Frontier for free!

This is Gerard O'Neill's classic work on orbital space settlements, and of course the primary inspiration for both our game and its title.  It was a hugely influential book, and happens to be a very good read too.  Every space enthusiast should read this book, probably more than once!
