Pinnacle Books, 1977
Price I paid: $1.50
It started with the smuggling of Mexican “wetbacks” for slave labor in the U.S. They were brought to an island in Lake Texoma, north of Dallas, to work on a top-secret operation directed by H.H. Christiansen…and were forbidden to leave. But it wasn’t until twenty-five Mexicans died in a mysterious tank truck fire that the Penetrator was called in. That’s when this simple smuggling assignment turned into a national security threat.
The project is the development of a sonic gun—the ultimate weapon—which causes the human body to explode from internal pressure, turning flesh and bone to jelly. The Cubans, the Albanians, and the Red Chinese are in on the buy. But the scientists working on the project are in need of a guinea pig—and Mark Hardin, the Penetrator, is just what the doctors ordered…
He has only one shot—to destroy the supergun before it annihilates him and all of the free world.
