The Skyhigh Betrayers (Penetrator #28)
Find Brunt Maxwell!
The urgent message flashes across the country as a scientist is reported missing from a California think tank where a new atomic shielding is being developed. The project is on the brink of success and will revolutionize travel, but no one has yet put the whole thing together into a practical unit.
Then the head man of the top secret project is murdered, and his assistant and number two genius, Brunt Maxwell, disappears... along with all of the plans.
It's a near-panic situation... national security is at stake... and time is running out-- even for the Penetrator!
