Koontz, R. Dean - Nightmare Journey

One hundred thousand years in the future, after man has been fatally humbled by his exploration of the stars and discovery of far more intelligent beings, civilization is struggling to return to the planet's surface. After man fled the stars, he tried to explore his own genetic frontier, creating horrible races of deformed beings- some scaled, soome furred, tiny, winged and huge. Now Jask, a Pure who retains the original human genetic code, and Tedesco, a great bear with a human brain, are thrown together by their one shared and fatal trait- telepathy. Hunted like animals by the fearful populace, they go in search of The Black Presence- which may be the key to mankind's place in the cosmos.
