Frank Herbert SF Gateway Omnibus 
The Dragon in the Sea, The Santaroga Barrier, The Dosadi Experiment

From The SF Gateway, the most comprehensive digital library of classic SFF titles ever assembled, comes an ideal sample introduction to one of the giants of 20th century science fiction: Frank Herbert. Although best known for his award-winning Dune, Herbert’s other work is equally ambitious and accomplished. This omnibus contains three novels spanning some 20 years of Herbert’s career: The Dragon in the Sea, The Santaroga Barrier and The Dosadi Experiment. THE DRAGON IN THE SEAIn the endless war between East and West, oil has become the ultimate prize. Nuclear-powered subtugs brave enemy waters to tap into hidden oil reserves. Psychologist John Ramsay has gone undercover aboard a Hell Diver subtug where, hunted relentlessly by the enemy, the crew find themselves isolated in a claustrophobic undersea prison, struggling for survival against the elements . . . and themselves.THE SANTAROGA BARRIERSantaroga seemed to be nothing more than a prosperous farm community. But there was something . . . different . . . about Santaroga. Maybe Santaroga was the last outpost of American individualism. Maybe they were just a bunch of religious kooks . . . Or maybe there was something extraordinary at work in Santaroga. Something far more disturbing than anyone could imagine.THE DOSADI EXPERIMENTGenerations of a tormented human-alien people, caged on a toxic planet, conditioned by constant hunger and war – this is the Dosadi Experiment, and it has succeeded too well. For the Dosadi have bred for Vengeance as well as cunning, and they have learned how to pass through the shimmering God Wall to exact their dreadful revenge on the Universe that created them . . .
