Georges gets bullied in school by some mean boys who call him Gorgeous.
Then Safer makes Georges his apprentice, and they have a mission to spy on Mr. X, a man whom Safer tells Georges he suspects of being a murderer. The missions get scarier, and Georges starts to wonder what he would do for his only friend.
At the end of the book, a few surprising things are revealed. It's hard to write anything more without giving something away, so let me just say that Liar & Spy is very different, unpredictable, and totally worth reading. I rate it five out of five stars in its own unique way.
