Hi! I'm looking for some good less popular books?

The Tripod Trilogy. Its an older series, written in the 1960s, but still very excellent. I had to read the first one for a class, got hooked and read the others. Its a post-apocaliptic series about humans enslaved by unknown masters who walk around in large three legged machines. The books are easy reads and very entertaining. They are: The White Mountains, The City of Gold and Lead, The Pool of Fire, and a prequel called When the Tripods Came.
