When the reclusive mathematician Jeremy Grady is murdered in a subterranean MIT computer lab, it's up to his estranged twin brother Jack to find out why. What could account for the sliver of ancient ivory that was found lodged in Jeremy's chest? And what to make of the image found on his computer thumb drive: snakes entwined in a double helix? Thousands of miles away, botanist Sloane Costa is searching the dark tunnels of the Roman Coliseum for ancient plant specimens. But what she finds is even more intriguing: an image of two opposing serpents wrapped in a double helix, and a bronze snake segment that seems to be part of something much bigger. Joining together, Jack and Sloane embark on a search for the truth that leads them on a far-flung journey-from Brazil, India, Peru, and beyond-as they unravel the mystery that links the Seven Wonders of the World, and discover a conspiracy to hide a roadmap to the Garden of Eden. As they get nearer to finding the truth, they are trailed by female assassins, who bear a striking resemblance to the mythological Amazons. Seven Wonders represents bestselling author Ben Mezrich's return to fiction: it's a wild ride of a novel with pulse-pounding action and fascinating historical references that will keep listeners captivated.
