The Rats Trilogy is the series that made James Herbert a household name. Beginning in 1974 with his debut novel, it follows the emergence of a mutant rat strain across three increasingly apocalyptic books. Each novel stands alone and can be read independently, but read in order they form a compelling escalation from urban horror to full-scale catastrophe.
Book 1
The Rats
1974 — Pan Macmillan
The novel that launched a career and redefined British horror. A mutant strain of giant black rats has emerged from beneath the East End of London and is hunting human prey. Art teacher Harris becomes caught up in a desperate race to identify and destroy the infestation before it consumes the city.
Fast-paced, visceral and shockingly graphic for its time, The Rats was an instant bestseller. Herbert drew on his East End childhood to create a vivid, authentic setting that gave the horror an uncomfortable reality. It sold over a million copies and has never been out of print.

Book 2
Lair
1979 — Pan Macmillan
Five years after the events of The Rats, a new colony of mutant rats has established itself deep within Epping Forest on the outskirts of London. Bigger, faster and more intelligent than before, they have begun to prey on campers, hikers and the inhabitants of nearby communities.
Lair expands the scope of the original while retaining its raw urgency. Herbert raises the stakes by moving the horror from the city to the countryside — where help is further away and the rats have had years to breed undisturbed.

Book 3
Domain
1984 — Pan Macmillan
Nuclear war has reduced London to a devastated wasteland. In the wreckage, the mutant rats have inherited the ruins — breeding in the underground shelters, hunting the scattered bands of human survivors who cling to life beneath the rubble.
Domain is the darkest and most ambitious entry in the trilogy. Herbert places his creatures in a post-apocalyptic landscape that gives the horror a nihilistic weight absent from the earlier books. A bleak, powerful conclusion to the series.
