What’s the lowest average rating of a book on Goodreads that you’ve read, and what did you rate it?

I was curious about this after checking the lowest rating on Goodreads for what to me was a 5 star read for another thread.

My top lowest rated books I've logged as read on Goodreads are:
2.65 – Death of a She Devil by Fay Weldon – I gave it 5 stars
3.06 – Not Forever, But For Now by Chuck Palahniuk – I gave it 5 stars
3.17 – The Doll Funeral by Kate Hamer – I gave it 5 stars
