35th anniversary edition with new text and a new preface by the author! Long ago, the Tripods — huge, three-legged machines — descended upon Earth and took control. Now people unquestioningly accept the Tripods' power. They have no control over their thoughts or their lives. But for a brief time in each person's life — in childhood — he is not a slave. For Will his time of freedom is about to end — unless he can escape to the White Mountains, where the possibility of freedom still exists.
