Joe Weber follows up his best-selling novel Rules of Engagement with another high-stakes thriller about a secret war and the courage of the men who fought it.The Vietnam War is at its height, and the US has acquired a Soviet-built MiG-17. Marine aviator Brad Austin has been recruited to test-pilot it. The MiG is an aerial hotrod, crude yet lethally effective. But it's not what Austin is flying, it's where-behind enemy lines, disguised as a Russian pilot. If he succeeds in penetrating the enemy air space, he will find easy prey. But if he fails, he will be disavowed.With edge-of-your-seat tension and gripping realism, Targets of Opportunity is thriller writing at its best!
