Evan Ryder is an extraordinary intelligence field agent now working for the security arm of Parachute, a private company and the world’s leader in the application of quantum technology. In the past, Ryder has done lethal battle in the modern global wars of power politics, extremist ideology, corrosive disinformation, and outrageous greed. But now she finds herself in a battle arena whose dangers, while less obvious, are greater than anything the world has seen before – the present and future war of weaponized quantum technology.
When an elite Russian scientist and the American Secretary of Defense die, at the same time half a world apart, of inexplicable sudden catastrophic brain damage, the world’s intelligence services realize that the quantum war has truly begun. Ryder and her long-time partner, Ben Butler, will risk their lives to discover who the true combatants are, racing against the doomsday scenario of all-out war between America and Russia.
Eric Van Lustbader is the author of many New York Times bestselling thrillers, including The Testament, First Daughter, Last Snow, and Blood Trust. Lustbader was chosen by Robert Ludlum’s estate to continue the Jason Bourne series. He and his wife live on the South Fork of Long Island.

Tokyo, late 2040s. It’s an ordinary world, one where cars drive themselves, drones glide across the sky, and robots work in hamburger shops. There are two superpowers and a digital Cold War, but all conflicts are safely oceans away. The new frontier: quantum computing – and it will change the world.
