I've always really liked this book for a few reasons. First off, it has two of the funniest moments in the whole series; Rachel's mom threatening a bear with a spice rack and Ax the juvenile delinquent. It's also a huge, fist-pump moment for Tobias, and despite the bittersweet-ness of the whole thing with Loren, it's probably the best thing that's happened for Tobias, really. I have to argue that the issues you pointed out didn't really hurt the book at all because they didn't really affect the plot or pacing; they were mostly minor oversights (then again, judging by your 9/10 rating, I'd guess you felt the same way).
Also, the mp3s are coming along sometime. I've been kind of busy/injured lately, and I either haven't had time to convert them or just didn't feel like it. Sorry.
