I started out liking the Weather Warden books a lot. As the series has gone on, though, I'm getting a little dubious. The pace of each book seems to be getting more and more frenetic. Having a sense of urgency is one thing, but this is starting to feel more like "if we go fast enough it'll make up for coherency or depth".
On the other hand, I was pretty "eh" about the first Morganville Vampires book. The second wasn't bad at all, and I actively enjoyed the third. I'm really looking forward to seeing the next chapter on that one.
