A prequel to The Tripods trilogy.
When it comes to alien invasions, bad things come in threes.
Three landings: one in England, one in Russia, and one in the United States.
Three long legs, crushing everything in their paths, with three metallic arms, snaking out to embrace – and then discard – their helpless victims.
Three evil beings, called Tripods, which will change life on this planet forever.
Christoper Samuel Youd, a.k.a. John Christopher (1922-2012), was a British science fiction author. He is best known for The Tripods trilogy.
