This is the final installment of the Rats trilogy (the others of which I haven't actually read) and finds London being destroyed in a nuclear attack, resulting in destruction, carnage and a race for any below ground structure that may offer shelter. As such those who survived the initial blasts were then terrorised by the black furred terrors that live below ground, away from the glare of the sun. As the rats find themselves in the majority and find food to be suddenly abundant they become more and more confident, venturing out into the ruined city and through the tunnels and chambers beneath, taking whatever and whomever they find. Herbert combines the terror of the nuclear age with the traditional horror that accompanies rats and their potential to overrun civilisation (or in this case what's left of it) to create a fast paced and disturbing tale of survival. My only issue is that it does get a little repetitive towards the end and I found myself beginning to lose interest, luckily this didn't last for too long but it was still there, otherwise a really good read.
