The title is kind of self explanatory. Or...so I thought. If you don't know what the world's end means, I suggest you type in "What is the definition of Doomsday?" in a Google search bar, then come back and read this book. If you do already know what it means, congratulations! Usually a book doesn't start with "Oh, yes, hello. Sorry, but I can't really talk right now seeing as how it's the end of the world. Enjoy your last moments!". So, how about we just back the hell up, yes?
