I did like Lord of the Flies because it was sociologically interesting--the way some kids became bullies, some became victims and some tried to just mind their own business and stay out of trouble--just like real life.

But as far as really crappy books go:

The Women's Room - (don't know the author) Real men-hating, self-pitying baloney by one of the women who gave feminists a bad name

Bright Lights, Big City - by some flash-in-the-pan, twenty-something, pseudo-author from the 1980's. Oh--was Brad Easton his name?? Horrible.

Any book by a guy named Gary Ezzo who writes child care books. He has no relevant professional credentials, espouses corporal punishment (for kids as young as 18 months!), encourages what amounts to neglect of the child and doesn't "believe" in attachment theory. A dangerous man who writes books for well-meaning, unsuspecting parents.

There. I feel much better now, thank you.
