Query: This book has never left my mind

I believe I read Suffer the Children when I was in middle school back in the 70's?? I guess I picked it up not knowing what kind of a book it was and I don't remember if I finished it but I know I will never forget the awful cave scenes. The seaweed and sand sandwiches will forever be etched in my mind and remembering all of that still disgusts me today! That book changed the way I read from then on...I've never picked up another novel that looked even somewhat similar in name or cover.
