If You're Reading This, It's Too Late by Pseudonymous Bosch
DO NOT READ THIS BOOK. For the story I am about to divulge is of an extremely dangerous nature. I fear for our lives. Yet how can I deny you the truth, when it involves a terrible monster grown in a madman's laboratory...a strange carved ball that sings of distant secrets...and the evil threat facing the youngest members of the Terces society...? If you insist on opening this book, never reveal the secrets within. Heed my warning...before it's too late.
