Collision of Forces — David F. Dehart

They're back! Dan Dailey and Bull are joined by Bull's son, Chris. In an adventure that ranges from sleepy Wilsonville, Oregon to Washington, DC, to the Middle East, the three are in hot pursuit of the bad guys. In this techno-thriller, the question is: Who are the real bad guys? The answer comes in an explosive climax in middle of the Black Sea. It's a fascinating read and a great addition to the "Dan Dailey" legend.
