"After a wild treasure hunt that almost got Gina, Edgar, Elena, and Kevin killed in a secret vault hidden in an abandoned amusement park, the GEEKs thought life would go back to normal. They'd saved their town from ruin and secured their friendship forever, right? Man, were they wrong. The only thing that returned to normal was middle school lunch. A company wants to reopen the abandoned amusement park, Bamboozleland, and it's just what the town needs! But a blogger from the next town over starts spreading vicious rumors that the treasure was fake and the GEEKs are a bunch of frauds. The GEEKs are determined to prove their puzzle-solving prowess, and what better way than another treasure hunt? A local bigwig sets up a new set of clues for them to follow, and this time the hunt will be documented. The GEEKs have already saved their friendship. Now they must prove that they are true treasure hunters!"--Publisher marketing.
