They slime, they ooze, they kill... A novel of mind-shattering horror, and a new breed of slime-ridden, oozing slugs lurking in the waist-high grass, developing a taste for new things...for blood, for flesh...human flesh!

Deep in the dirty sewers of London there is a Breeding Ground ... The slugs have come back ... slowly... silently... they slither along dank, fetid tunnels into the city in search of human flesh. Their insatiable need knows no bounds. But now they bring a new horror - a plague which spreads insanity and death, transforming its victims into grotesque, crazed killers. Caught in this maelstrom of horror is Dr. Alan Finch - the only man capable of destroying the Breeding Ground forever...
