The audiobook of this that I listened to is available for free at LibriVox.
The end of this book was a little more hopeful than I expected. It was already quite clear that our narrator was going to live, since he's narrating after the fact. Him living implies that the Martians either die or leave Earth before they kill everyone.
I found the way the Martians died reminded me of Jared Diamond's Guns, Germs and Steel: they might have have a huge technological advantage, but Earth germs got them anyway!
I found the explanations of the aliens and their craft to be kind of terrifying, which was Well's plan, I think.
I love that we can do half stars on BookLikes!
