Prequel to the Tripod series.
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.
This prequel to the well-known Tripod series provides the logical, ingenious, and frightening explanation of just how the Tripods were able to take over most of the world.
