Indeed Mrrzy -- esp The Midwich Cuckoos, a really creepy bit of spec dystopia. The film version, Village of the Damned, just got it subtly wrong by trying to make what are subtle hints in the book over-explicit, and lost all the atmosphere.

And Chocky, tho not a particularly impressive one, has one brilliant feature. I had never understood binary -- and tried looking it up again on Wikipedia the other day & found my head spinning in two seconds. But then I go back to Chocky, where in about 5 lines & using Y & N [for yes & no] instead of 1 & 0, the concepts of binary are explained with hyaline clarity by one character to another -- and even to innumerate boobies of readers like me!
