That is what Jack has always told him, and everything Andrew has learned from his dad’s favorite spy movies tells him it must be true. When Andrew comes across his brother’s graphing calculator, he’s sure it’s a communication device that will put him in touch with the secret spy headquarters. But instead of punching in a greeting to the spy society, Andrew accidentally punches in a code that might blow up the world! And if that isn’t bad enough, his math teacher then confiscates the top secret communication device and takes it to the mysterious Storage Room B. Now Andrew is on a spy mission to find his brother’s communicator and save the world from mass destruction. Will he be able to save the world? - from Amzon
