Technically I am also in the middle of the Inheritance series (Paolini), but I was a little put off by book two, and while I'll finish it, I'm not chomping at the bit to finish it. I've also read books 1 of Artemis Fowl and Leven Thumps. I'll finish Inheritance, but I don't feel driven to read either Artemis Fowl or Leven Thumps. Not to say that I'll never finish, but I don't see what the big deal is.

Did you count?

That's 12!

Yikes.

What did I do to myself?

And yet, when someone recommends something new I am all over it.

If there is a question mark, then I have based the month on when the previous book was released on Amazon.
