"The Twilight River Werewolves, vampires, and magicians mingle uneasily with the enslaved humans of Earth's far future, chattels fo the alien Rangels. Dreadful Sam, the music man, and Trinna, the warlock's daughter fleeing the wrath of the Rangels, voyage down the Twilight River in search of the Lair of Free men - the last hope of human dignity in a ruined world. The Tery (LaNague SciFi Series # 5) Far across the galaxy an ancient battle is fought once more, with new combatants: the furry, four footed - yet disturbingly human - teries, and their human persecutor, tyrannical leader of a fanatic religious sect. One tery dares to face the enemy with the ultimate heresy - asserting his identity as a man."
