When the shy mathematician Jeremy Grady is murdered, it’s up to his estranged brother Jack to find out why. His search leads him on a far-flung journey—from China to Peru; Egypt to Brazil—as he unravels the mystery that links the Seven Wonders of the World, and discovers that Jeremy may have hit upon something that has been concealed for centuries. With the help of geneticist Andrea Costa, they discover a conspiracy to hide a roadmap to the Garden of Eden—and the truth behind a mythological ancient culture. First in a trilogy.
