Alright folks, since none of you knew what the heck I was rambling on about, I got off my ass and did my own research. The book I was talking about is called "The White Mountains" and it was originally copywritten in 1967 by John Christopher. The second edition was published in 1988, which explains how I remembered it from elementary school. Two sequels were published...."The City of Gold and Lead" and "The Pool of Fire", as well as a prequel "When the Tripods Came", released most recently in 1990.
