Austin Davenport is back for his final middle school adventure. Three years of mayhem at Cherry Avenue come to a head as the greatest middle school rivalry known to man gets ready to explode! It's Austin and Randy's craziest battle yet. A battle of the minds. The sworn enemies both dream of walking across the graduation stage as valedictorian, but only one will survive...the contest. Nobody is going to die. I mean, let's not get carried away here. It's still just middle school. There might not be death, but there will be mayhem and many questions to be answered! Who will win in a battle of wits? Will Austin triumph over evil? Will a political scandal threaten to take down Sophie's presidency? Will Ms. Pierre (Principal Armpit Hair) finally get the best of Austin and the rest of Nerd Nation? And topping it all off, Author C.T. Walsh makes another Cherry Avenue appearance after stealing the show in The Comic Con (Middle School Mayem book eight)! Who doesn't love this guy? The biggest question, perhaps, that everyone wants to know- Will C.T. save the day? The answer is- No. No, he won't. Graduation Detonation is sure to ignite your interest and reading pleasure! It has explosive potential (and not just the fart jokes)! Tune in to Nerd Nation to see how Middle School Mayhem ends. Well, besides in mayhem. There are fine details that you should be aware of. Well, what are you waiting for?
