With great difficulty, Logan, Zoe and Blue managed to save the Menagerie, but before they even had time to catch their breath, a new disaster happened. Someone has killed a gold-bearing goose, and all the evidence points to a dragon named Scrape. As an intelligent creature, Skreb is entitled to a fair trial, but there is very little hope of bailing him out. If the dragon is found guilty, he will be executed for murder and the Menagerie will be closed forever. The guys have only a few days to find the real criminal. After all, Skreb can’t possibly turn out to be him... right?
