Robert Ludlum's The Bourne Escape

The death of a lover plunges Bourne into a maelstrom of violence and deceit in this latest installment in the #1 New York Times bestselling series. Jason Bourne is on a boat in the Mediterranean moonlight with his lover, Johanna. He's happy for the first time in years. Then in the next instant, he finds himself floating on wreckage as fire and smoke choke the sky. Johanna is gone. And Bourne finds the darkness of lost memory closing around his mind again.
As he did once before, Bourne must piece together the fragments of who he is, even as assassins hunt him across Europe. He teams up with his spy chief, Shadow, who reveals the shocking secret that Bourne's surrogate father - David Abbott, the founder of Treadstone - is alive and missing. Together they must find Abbott before his enemies do. But Shadow is a master of manipulation who won't hesitate to betray Bourne to get what she wants.
With his memory returning in bits and pieces, Jason discovers that the explosion that stole away his identity is part of a deadly game being played among powerful adversaries from Moscow to Washington. It's a game with no winners - because even if he finds David Abbott, Bourne may still find himself with no way out and everything to lose.
