There's something subtle about these books. They're calming even though the plots aren't. i feel relaxed the whole time I read them. It's very odd. No other series makes me feel that way. And, while that may sound like a bad thing in a book, it's not. I love this series. I don't know if it's the artists style, or something to do with the stories themselves, but either way, I always look forward to reading about Vi.
