I will admit, the initial premise of how the surface world was destroyed was a bit ridiculous, but get over that quick, because the entire book is RIDICULOUS and it’s one of the most appealing qualities of this book! I was repeating Carl’s catchphrase before I even knew it was a catchphrase. I laughed out loud multiple times. I couldn’t wait to get back to the story, which is a sure sign of a great audiobook! I highly recommend this book.
