I you have ever finished reading a book and thought to yourself, "there's several hours of my life I'll never get back" or "I wonder how many IQ points that cost me", then post it here.
I'll start with "Still Life With Woodpecker" by Tom Robbins. I have no idea why I even finished reading it. Glutton for punishment I guess.
I'll add more as I think of them.
What's your worst reads?
