Forbidden is book 1 in the Luna Lake series by Cathy Clamp. It brings the world of the Sazi (Hunter's Moon) to 10 years after the plague. I have not read the Sazi series but you do not need to have read it to read this. This book had a very interesting plot, that begins RIGHT at the start. It centers on Claire, a young Wolven agent goes to Northeastern WA to investigate some missing children. She meets Alek, a red wolf shifter who is trying to become a Wolven agent. Together they investigate the strange goings-on in Luna Lake. Lots of great characters in this one. If you enjoy shifters, you should read this one. It doesn't come out until August 11, 2015 (per Amazon).
