I challenge you to . . .

. . . find books over 4.0. I'm wondering what they highest we can find is. There isn't a way of viewing books ordered by rating so it's not easy.

I think it's best if they have more than say 2000 ratings

4.41 - part of a series though

Looking through my bookshelf, the highest rated book is the Hunger Games at 4.54. I suspect a raft of teenagers scoring OMG it's amazing 5's though! second is The Help with 4.45.
Lowest is 'Her Feaful symmetry' with 3.71 although I only gave it 2 stars so I think that's quite generous.
I do take the scores with a pinch of salt though, bearing in mind Twilight scores higher than Animal Farm

True, true Jo. I think teen/fan fiction can't really be counted on - not only will it be scored too highly by some but will also be scored too low by others.
4.45 for The Help is a good score though:)

The Complete Tales by Beatrix Potter is a 4.30 on my list although it is a series.
Anne of Green Gables has a 4.21
