Query: The first chapters are enough to stop anyone sleeping

the moon is a gripping and scary thriller from start to end, the first chapter of the dark is the most gruesome and detailed ive ever read, so intruiging its hard to put the book down, you might need to sleep with the light on for the first 5 chapters or so. The book is a master piece allways with a twist that makes the book even more worth reading, if it is at all possible
