A tiny programmable device, Spyder can pry open the most heavily guarded computer networks in the world and do the work of hundreds of field agents and teams of elite computer hackers. Now the battle to control this confidential technology has begun, and a former U.S. Navy SEAL has walked into the middle of the fight."--BOOK JACKET.
