Book 1 :Read in the 1950's . Youth or Young Adult. People had to stay in at night because there were scary mutants. There were a few line illustrations in this book with pot bellied almost beaked mutants with lots of sharp teeth. Any one know this book ? Book 2: Read in the 1970's. Apocalyptic catastrophic, or dystopian. At the end of this book was a suggested reading list related to some of the issues in the book.I thought it might have been Lucifer's Hammer (because one of the books listed was mentioned in the story) or The Stand but there are no reading lists at the end of these books . I've been looking for years. Any guesses?
