Seal Team Seven #17: Payback

When local law officials investigate suspicious activity at an offshore California oil rig, one-by-one, they turn up dead. The situation calls for a covert underwater raid by the Navy SEALs. It turns out North Korea is secretly using the oil-rig platform as a base for a retaliation effort following their defeat by South Korea and the U.S.
 
Now, North Korea has nine missiles ready to launch. And it’s up to the SEALs to dismantle the operation and force them to surrender—or sink.
