Evil never takes a vacation.It's been two months since the Kaplan family hunted down the Serpens relic, and the malicious, conniving Galina Krause seems to have dropped off the face of the earth. But it's only the calm before another terrible storm. She and her lackey Ebner von Braun suddenly and violently reappear in the South of France, stealing a rare sixteenth-century astronomy book that will lead the villainous Order to the next Copernicus relic.Wade, Darrell, Lily, and Becca have no choice but to get back in the game and square off against Galina in a desperate search for an artifact said to be crafted by Leonardo da Vinci himself-perhaps the strangest Guardian of all. The dangerous chase leads the Kaplans from Morocco to Monte Carlo, but along the way they uncover another layer to Galina's sinister endgame . . . and there might not be enough time to stop it.Filled with pulse-pounding action and cryptic codes, The Golden Vendetta is the third engrossing book in bestselling author Tony Abbott's cloak-and-dagger series for young readers.
