This a sort of activity book about many different doors and anything that is in a cabinet or small space. Is a book where you touch and flip open various flaps on each page. You also search for certain things on each page as well. So this book is both a flap and seek and find type of book. The settings range from fire stations and boats to hospital offices and castles.

This is a serious lift-the-flap book, often with multiple flaps over each other. It is therefore not for very small children, but it does appeal to a very wide age range, as adults admire the engineering. It shows doors in a wide variety of contexts of interest to children; a space station, a fire house, a doctor's office, a refrigerator, a stable. The pictures are detailed and interesting, with little visual jokes, and there are things to look for on each page. The hidden objects are not terribly difficult to find, although they sometimes require some flexible thinking (and of course they're often behind doors). It's probably not difficult enough to interest serious searching afficionados, but for more casual searchers, it's got a lot going on, and it will hold an adult's attention for multiple readings. ( )
