So I recognize that the late request is my fault (sorry, Im new). So I am going to call an audible this month for two reasons. The upvotes and suggestions seemed to favor John Dies at The End, which I think is a great choice in general to read in October. In the future we'll have a proper vote and get started earlier. I will take all the nominees from this list and add them to a post for next month and we'll get a proper vote going for November.
October Book Club is John Dies at the End.
