***NOTE: All are in great condition except book 1, which I’ve owned for the longest and has some peeling of the cover (see photos for reference). Not only is the name of this series a secret, but the story is, too. For it concerns a secret--a big secret--that has been tormenting people like you for over . . . oh no! Did I just mention the secret? Then it's too late. I'm afraid nothing will stop you now. Read this series if you must. But please, tell no one. Catch up on the adventures of Cass and Max-Ernest with The Secret Series Collection. This boxed set includes all five hardcover novels in the New York Times bestselling Secret The Name of this Book Is Secret ; If You're Reading This, It's Too Late ; This Book Is Not Good for You ; This Isn't What It Looks Like ; and You Have to Stop This .
