A quick starred breakdown of all the books (across all genres/categories) I've read since the start of this year. I'm doing really good at giving up on (abandoning) books that I'm not liking -- you can tell this because I only have 1% of books rated one star. I could do better on giving up on the 'meh' sort of two star reads though.
Still, fully fifty percent (wow!) of what I read I'm really, really liking -- all four or five stars.
