Hunted - P.C. Cast, Kristin Cast

Hunted is book five of the House of Night series.  This book has lots of big changes in it.  The kids, along with the rest of the world, are in some serious danger.  Zoe and her friends and Grandmother and a Nun have to come together in a new way.  At least this one ends with something of a hiatus so the next book is not needed right away.  I really enjoy this series though.  It's kind of like a modern Nancy Drew with the supernatural, vampyres, and significantly more making out added in.  Maybe not like Nancy Drew after all :)  Highly recommended.
