Having finished Behemoth, read on old-fashioned paper, I have to say that I really do like some of Westerfeld's stuff. His writing may not especially impress me, but he does have a crazy mind full of fantastic ideas. Of course, some of those ideas don't pan out (or so I've heard about what happens in Peeps). Anyway, I'm still totally digging this completely ridiculous and delightful revisionist history.
One nice thing about not having the audiobook, even if I do miss Cummings' vocal stylings, was getting to see the illustrations. They're really awesome and definitely a nice spice for the eyes (if you've read the book, you know what I did there).
Unlike the Uglies series, I also really like the characters, except for Dr. Barlow, who I still find annoying. Alek is a bit stodgy, but generally a nice kid, suffering only from his rather unique upbringing. Dylan is an awesome girl, who does not let mooning over a boy stop her from being a badass; she can moon and be a badass at the same time. My new favorite character, without a doubt, is Bovril, a perceptive new beastie.
If you enjoyed the first installment, you will not be disappointed by this one, unless you wanted more than five pages of the title beastie. Next up is the final book in the series. I am so ready!
