Black Wind — Clive Cussler; Dirk Cussler

In the waning days of World War II, the Japanese tried a last desperate measure--sending two submarines to the United States armed with a new biological virus. Neither sub made it to the designated target. But that does not mean they were lost. Someone knows where the subs might be, and has an extraordinary plan for the virus --a scheme that could reshape the world as we know it. All that stands in the way are three people: a marine biologist named Summer, a marine engineer named Dirk, and their father, Dirk Pitt, the new head of NUMA. Pitt has faced devastating enemies before, and has even teamed up with his children to track them down. But never before has he looked upon the face of pure evil . . . until now.
