They call it Spyder: a supposedly undetectable intelligence-gathering computer program that can easily penetrate heavily-encrypted computer networks. When ex-Navy SEAL Nolan Kilkenny discovers its existence, Spyder has already been stolen by three indusrial spies in a heist that quickly escalates to murder and treason. Suddenly, Kilkenny is leading the FBI and CIA in the search for Spyder... and is in the crosshairs of those who will stop at nothing to possess the ultimate spy weapon.
