William M. Corry, captain of the American super-sub, the U.S.S. Shenandoah, was certain his new mission was not as simple as it first seemed. His initial orders were for a shakedown cruise, but those were quickly countermanded by another directive to proceed to the Solomon Islands. Yet Corry's gut feeling was that this was all a coverup for something far bigger. And he was about to be proved right! Told to rendezvous with and take on board a scientific team, Corry learned that the Shenandoah was at last going to be allowed to track down the alien invaders who were based beneath the sea — and this time they were going to bring one of the creatures back alive!
George Harry Stine attended the University of Colorado in Boulder. Upon his graduation he went to work at White Sands Proving Grounds, first as a civilian scientist and then, from 1955–1957, at the U.S. Naval Ordnance Missile Test Facility as head of the Range Operations Division.
Stine and his wife Barbara were friends of author Robert A. Heinlein, who sponsored their wedding, as Harry's parents were dead and Barbara's mother too ill to travel. Several of Heinlein's books are dedicated one or both of them, most particularly Have Space Suit - Will Travel. Stine also wrote science articles for Popular Mechanix.
Really liked the first book in this series. And it pains me to give a negative review to a book by Harry Stine, who I greatly admired. But this is a step down from the first; deciding to invoke just about every alien conspiracy trope to expand his setting feels like a mistake and it greatly reduces the feeling of verisimilitude he evoked in the first book. Still has its moments and I still enjoy the interaction of the characters, but it's just not as good as it started out to be.
