Behemoth, Westerfeld. Yes. Follows Leviathan, with apparently one more to come in the series. Classified as YA by my library, it’s certainly not a dense read, though it does have a number of interesting ideas threaded through. I was appalled to see “led” spelled “lead” at least twice (spelled correctly at least once); it’s a depressingly common résumé error, and it’s very disappointing to see it creeping into prose. That was really the only issue I had with the book, though: I like the characters, and their adventures do not leave my eyes rolling out of my head, and there haven’t been many books lately that I’ve breezed through quite so pleasantly.
