I liked it.
If more of the book had been written like the last few chapters, I might have loved it. There were some good bits. But for a LOT of the book, I was bored. I knew stuff was going to happen. But the writing style left this gaping chasm between me and Penryn for most of it, so I was rarely drawn into any of it. When there was action, though, the writing was tight, and that's when it had me. So far, that seems to be my main problem with YA - the opinionated narrators. I'd rather just be shown what's going on and form my own opinions.
At the moment, though, I am tempted to check out the next one... That being said, I might forget by the time October rolls around...
