An excellent, well-crafted novel that mixes science fiction and horror with masterful results, THE LAST ASTRONAUT is full of adventure, mystery, and terror. In some ways, it reminds me of Jeff VanderMeer’s ANNIHILATION, with its human characters trying to make sense of completely alien surroundings, and in other ways it reminds me of a haunted house story, where the farther our characters explore, the more its secrets are revealed — sometimes terrible, sometimes awe-inspiring, and sometimes inexplicable. David Wellington has done a fantastic job not just with his use of realistic science but also with creating something so completely alien that it seems insurmountably unknowable. I hope this novel gets the attention it deserves. It’s one of Wellington’s best yet.
