This is a hugely acerbic, mobius strip-esque novel that weaves in parallel realities and explores the concept of archetypes in a post-apocalyptic wasteland following an ecological disaster. Saying that means nothing; Dead Astronauts is, like so much of VanderMeer's work, a book where the prose and format are immensely important to imparting the surreality of death and destruction. In this sense, it's like ecological ergodic literature - you travel throughout different perspectives of machines, mutants, creatures, and survivalists in which the organization of words on-page tells you more about their lens and experiences than the actual words on-page. Some reviews of this book lamented the difficulty in following the plot, but that's kind of the point - if you're interested in a speculative fiction take on early 20th century modernism and mid-20th century environmentalism (though that's putting it too reductively), then this is absolutely for you. Given VanderMeer's residency in Tallahassee, FL, it's hard for me to imagine he isn't a little bit inspired by fellow USA southerner William Faulkner.
