The Zenith Angle

Pioneering computer wizard Derek "Van" Vandeveer has been living extra-large as a VP for a booming Internet company. But the September 11 attacks on America change everything. Recruited as the key member of an elite federal computer-security team, Van enters the labyrinthine trenches of the Washington intelligence community. His special genius is needed to debug the software glitch in America's most crucial KH-13 satellite, capable of detecting terrorist hotbeds worldwide. But the problem is much deeper. Now Van must make the unlikely leap from scientist to spy, team up with a ruthlessly resourceful ex-Special Forces commando, and root out an unknown enemy--one with access to a weapon of untold destructive power.
