My rating: ★★★★

What is it like to live on a generation ship? What are all the things that can go wrong? How pedantic do you need to be about your resources? What do you do when you get to your destination. Kim Stanley Robinson digs into all these questions and more. To quote from the book summary: “Our voyage from Earth began generations ago. Now, we approach our new home.”
