What a delightful book!
Actually, I started reading this a couple of weeks ago, got into it a few chapters, and then got bored and started reading something else. Last night I picked it up again. And oh, my goodness!
In the very next chapter: Cannibalism! Bad bats! Danger and excitement! Lots of surprises!
I read straight through to the end, and I really enjoyed the ride. There's a whole series of these books (which are technically written for children, but, who cares?) and I'm pretty sure I'll be reading more of them.
