Help Me Choose A Book?

I'm trying to decide on another ebook to buy for my Kindle and obviously this is a really big decision. I have a few books I'm thinking of, but feel free to recommend something not on the list. (Don't worry too much about whether it's in ebook form... I'll check.)

here's a question, blog

As you can maybe tell, I'm still working on the whole figuring out what this blog is going to be thing. With a book blog, it was easy: book reviews, discussions, lists, favorites. This time around, it's a bit more difficult. I want to talk about books but how much is too much? I want to talk writing, but don't want to talk about my querying process and don't especially feel qualified to give writing advice.

So I must turn to you, blog, and ask WHAT DO YOU WANT TO TALK ABOUT? Or, erm, what do you want me to talk about?
