Here’s an author who knows how to get kids to read: use reverse psychology in the title and then make the first test whether they can actually get the book out of its slip case! Inside there’s a multicoloured stash of secret stuff about UFOs, safecracking, what’s in your food, what’s in the Vatican and whatever happened to Elvis. There are also a couple of spreads that will make parents nostalgic for the old Magic Eye pictures – if you once cracked the code, you can probably still do it.Age 10+
