Will has escaped from the City of the Tripods to deliver terrifying information to the colony of free people: The Masters are planning to change the earth's atmosphere to that of their own planet, exterminating the human race. There isn't much time to stop them, but Will and the others have no alternative but to try. Will they succeed in freeing the world from the control of the Tripods? And if they do, what will a free world be like after centuries of domination?Thirty-five years after its original publication, we are proud to offer this anniversary edition of The Pool of Fire, featuring a new preface from John Christopher, as well as the author's fully revised text, available in the United States for the first time.
