When worrywart Chen Connelly finds a mysterious antique book beneath a park bench, his safe but lonely summer suddenly becomes exciting. Perhaps a little too exciting. A book of renaissance architectural designs may not seem particularly exciting, until Chen finds himself traveling through the pages of the magical book with Polly Goggin, the weirdest girl he's ever met, as they race to solve the clues to a treasure hunt left by Benjamin Franklin, struggle to find their way through a maze of mysterious doors, and dodge far too many angry security guards. It doesn't help that a murderous, strangely nondescript magician-thief is on their trail with a magic book of his own, willing to do whatever it takes to get his hands on Benjamin Franklin's treasure and all three extraordinary books. Turn the page... Open the door... Enter the adventure...
