The Name of This Book Is Secret


Pseudonymous Bosch - 2007
    As much as he'd love to sing the praises of his book (he is very vain), he wouldn't want you to hear about his brave 11-year old heroes, Cass and Max-Ernest. Or about how a mysterious box of vials, the Symphony of Smells, sends them on the trail of a magician who has vanished under strange (and stinky) circumstances. And he certainly wouldn't want you to know about the hair-raising adventures that follow and the nefarious villains they face. You see, not only is the name of this book secret, the story inside is, too. For it concerns a secret. A Big Secret.
