Shhhh! Just Between Friends: How To Keep Things Totally Secret

The book is crammed with super secret-keeping stuff, like secret notes (how to fold with flair), secret languages (Pig Latin, Double Dutch, and nine more), secret codes (including phone-less texting), secret signs and symbols (say it with socks), and e-secrets (the silliest emoticons ever). There are even two bound-in decoder wheels for deciphering secret messages.
