First off this book has no depth whatsoever to it. Also the story is quite boring. In most novels there was something more interesting going on, but not here. The characters are all so flat, I actually didn't learn very much from their lives. The only thing holding me back from giving up on it in frustration at page 110 or so had been that for some reason i kept thinking surely someone will find a way out. But I'm still stuck with it. For now I'll keep reading.
Bad review
