nice book to my opinion but still pretty sad. It has history to it.

I loved this book but it was kinda sad but I really recommend this book. if you don't like a sad book then i don't recommend this book.

Hidden is such a great book it got a little scary but still soooooooooooo good 👍 👌 😀

Hidden is a sad story, but its still good. what is a good part is it teaches us about history.

Such a creat book and great to teach kids about World war two
