The Golden Vendetta is bestselling author Tony Abbott's third full-length book in the page-turning, pulse-pounding Copernicus Legacy series. When the Kaplan family learns about the theft of a rare sixteenth century astronomy book in the South of France, Wade, Darrell, Lily, and Becca have no choice but to throw themselves into a desperate hunt for a mysterious golden hand, said to be crafted by Leonardo Di Vinci himself. In the dangerous streets of Morocco, over the ancient stone pathways of Malta, and in a crucial and deadly undersea battle, the Kaplans must face the most sinister members of the Teutonic Order to continue their quest to protect Copernicus's precious legacy.
