Nikhil Nanda thought his days of danger were behind him until a desperate call from Paris shatters the calm. His former student, Ned Nelson, has just survived a knife attack. "It's happening," he says, "The research. Someone's after it." The discovery: a revolutionary metamaterial that bends light and renders objects invisible. The threat: a shadowy, powerful figure determined to claim it, at any cost, for his country, to tilt the global balance between the East and the West. As assassins close in from Oxford to Paris, and Lucerne to Viareggio, Nikhil must act. He calls on Tina Kohli, the beautiful and brilliant Formula One manager who once helped him keep an impossible promise. Together, they assemble a team to rescue his ex-student's family on the windswept cliffs of St. Kilda, Scotland, and the back alleys of Tashkent, Uzbekistan. But to end the threat, Nikhil must team up with an American traitor and journey deep into the lion's den, Beijing, China, on a mission no one else can know about. Gravity of a Vision is a high-stakes, globe-spanning thriller about the power of science, the price of loyalty, and the unbreakable bond between a mentor and those he's sworn to protect.
