Good story but what really confused me was that, despite the title, there were no Ghast in this book. The title makes zero since. Why name a book, "Ghast in the Machine", if there are no actual Ghast in the book? They were going in and out of the Nether a lot, but only at the beginning of the book did the author really write about them being in the nether. And that wasn't even about Ghast. It was about Wither Skeletons. And anyways, you can't name a book about something and only have the first chapter talk about it. That doesn't make any since. This book was more about Jodi spying on her friends and exploring the Overworld, not fighting Ghast in the nether. I kinda feel like the author, no offense, named the book, and then kinda forgot about what he was supposed to write about, and instead made a totally different story. But if you are looking for a book that's about Ghast (for some reason), don't get this one!
