Maxim Gunn and the Serpent Force

The alignment of all nine planets will bring the Serpent Force, a mysterious power known to the ancients, to its maximum effect. One man has the secret and must be stopped. Once more Maxim Gunn is on the trail which takes him from Stonehenge to the temples of Greece and the Mayan ruins in the Yucatan. Earthquake, unseen powers, duels with the forces of evil, and time running out leave Gunn little time for sight seeing. It's a race which must be won, for the consequences of failure are unthinkable.
