I've read The Exorcist and everything by Stephen King...all the obvious stuff like that. I'm really looking for lesser-known books that I probably wouldn't have come across on my own--you know, all those mass-market paperbacks that proliferated in the '70s and '80s especially, with black covers featuring creepy-looking children... :D

Haven't read the John Wyndham, though, and I loved the movie, so I'll check that out. That's exactly the sort of thing I meant. Thanks. :)
