FWIW, since I have issues with completing series, I read the second one right after the first. Then I waited until the third came out and was under the mistaken impression it would be the last. I was furious when I realized it wasn't (and it was so not good, stop before you get there). I decided that I'd only read the fourth (when it comes out) if there is no fifth. Because I want closure, but maybe not that much.
apostrophe errors drive me crazy too! thanks for the review. i think i'll wait to read it til my TBR pile thins out.
