The world's most ruthlessly efficient assassin, Jason Bourne, has carved a bloody swathe through all his opponents but now he's facing the one force he can't defeat - his own past - in the latest thrilling entry in Robert Ludlum's New York Times bestselling series. Three years ago, Jason Bourne embarked on a mission in Estonia with his partner and lover, a fiery UK-based Treadstone agent codenamed Nova. Their job was to rescue a Russian scientist and activist, the leader of an anti-Putin protest movement, who'd recently been smuggled out of St. Petersburg in the midst of an FSB manhunt. They failed. Now, three years later, everything has changed for Bourne. Nova is gone, killed in a mass shooting in Las Vegas. Bourne is a lone operative working in the shadows for Treadstone. He's ready for a new mission when his handler bring him shocking news. The Estonian mission was a set up. Their target had not been killed. She is still in hiding in Russia and the Russian State Intelligence Agency is desperately seeking her. Bourne must find her first, but his race to correct the errors of the past will lead him to one inevitable conclusion: Some secrets should stay buried.
