From the Publisher
This book is crammed with super secret-keeping stuff: note-folding instructions, secret languages, codes, signs and symbols, and the silliest emoticons ever. To top it off, any note you write with the invisible ink pen looks completely blank — until you shine the built-in UV light on it and your message glows.
