It began with a few small items in the newspapers - dead dogs and cats, a mutilated child, a series of unexplained fires. Then suddenly it exploded into a full sized catastrophe. Huge mutants - half rat, half man - began to take over the world, stealing children for slaves and destroying their populations. Only a few people escaped, among them Tim Barrett, his wife Jane, and a handful of survivors. Alone on the high seas in a small ship, they set off to find the island where Dr. Theodore Piper had been experimenting with a sonic death ray. They knew Dr. Piper was their only hope for personal and world survival—if he was still alive... if the King Rats hadn’t forced him to serve their evil purpose... and if he could find a way to stop the spreading horror of invasion.
