I really enjoy this series. If you haven't tried it yet, I highly recommend. I was hooked to my by Jen from redhotbooks. I really glad I started them. I took a long break between the second and third books. I just had too many other books that I needed to get read and other things that limited the amount of time I had to read. Because of this, it took me a little bit to remember where everything was going in this series. Also, this takes place in a completely different setting. We learn a lot about the Hopi culture and their multiverse or underworld. Livvy is the only character from previous books that is in this book until SK shows up about halfway in. We meet a lot of new characters. Many I liked and many I didn't.
Just a great all around story. I really thing you should give it a try. It is something completely different from the majority of the books that are coming out these days. I really enjoyed.
