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.

Wilson delighted readers with his first unforgettable action-adventure story of survival. . . .  Thomas Hammond has always lived next to Leepike Ridge, but he never imagined he might end up lost beneath it! The night Tom’s schoolteacher comes to dinner and asks Tom’s mother to marry him, Tom slips out of the house and escapes down a nearby stream on a floating slab of packing foam.

Flung over rapids and tossed through chasms, Tom finally hits shore, sore but alive.

Now, if only he can find his way home again. . . .

And suppose that another set of twins-adults-named Dean D. Dean and Dan D.

Luckily for you, this is just the first in a series perfect for boys and girls who are smart, clever, and funny (just like the twins), and enjoy reading adventurous stories (who doesn't? ).
