Yep, I'm in again, and agree, wouldn't want them to be all the same genre! The whole point of the circles for me is that it challenges me to read outside of my comfort zone! Like others there have been some I wasn't keen on, but I've also found some absolute gems, and many of them I wouldn't have tried without the push of it being a circle book!! My current one is a perfect example of this, I'd never in a million years given it a go on my own, I doubt I'd have even got as far as the blurb, and if I had, I would've dismissed it, but I gave it a bash, and LOVED it!!
I also agree about no series books, unless it's the first, I've had a couple, and had to miss them out! And I know some people say that some series books can be read as stand alone, but I am such a pedant when it comes to these things, I HAVE to read series in order!!
Ooh excited, am off to have a nosy at my books, see what can be my contribution!!
