It’s a little too earlier to say very much. I don’t write Sci-Fi so it’s hard for me to understand the finer points but I think maybe a few more details can help. I did not expect humans to be wiped out like that, but that’s the direction the author is going, so it’s different then what I imagined. If you are a sci-fi reader you may want to give it a read. I’d like to see what the author plans to do now.
