I read and reviewed, separately, the three books in this series earlier this year so I'm just adding this now for completeness. These were some of the defining books of my childhood - not the most important, but certainly up there. The first two especially I thought were excellent, but I was then (and remain now) a little disappointed with the last by comparison, and by the lack of girl characters in general. Still, the overwhelming creepiness of the Cap, of the Tripods and the way that they chewed though servants in their dreadful cities, was just so well done I never forgot it.
