Time is ticking as the countdown to total school demolition continues.
But in addition to deciphering maritime clues that could save the
building, Ben Pratt and his friend Jill have to stay one step ahead of
Lyman, the snake posing as the school janitor--who will do anything to
preserve the $30 million development deal that pays his salary.
The second book in this riveting six-book series is as action-packed as
the first one, culminating in a faceoff between Ben and Lyman. "After
five bells sound, time to sit down" makes for a good riddle, but Ben
also knows when it's time to stand up...for Oakes School and for
himself.
