The Bourne Supremacy (Bourne Series #2)

David Webb is an ordinary citizen living an ordinary life in a small university town...except he is under 24-hour personal surveillance. Of course his memory is gone, but with his wife's loving care his past is on the mend.

Suddenly it returns, but not at his volition. From Hong Kong comes word that the assassin has struck again, that Bourne is back!

But the U.S. government knows he never existed. Webb only posed as Bourne to unearth a notorious killer. Yet someone is killing again in Bourne's name...and he must be stopped or stability in the Far East will crumble. The decision is made -- Jason Bourne must exist again and hunt his own imposter.
