They reintroduced Weather - and they were broken up as I kind of thought they should be at the end of the last book. I don't think we've seen the end of Weather and Lucas but I do think that they need more time before plunging back in.
Also, Lucas finally gets to have a fling with Marcy, which is good.
Finally, the predator in this book was AWESOME. First female "bad guy", I think, and she was CRAZY bad. Loved it.
One of my favorite in the series.
