Mortal Ties (World of the Lupi #9) by Eileen Wilks

I do love this series.  Poor Lily can’t catch a break.  She is living at the Nokolai Clanhome planning her wedding to Rule when one of Cullen’s magical experiments gets stolen.  Is there a traitor in the pack?  Who would've stolen it?  Then there is the fact that Lily’s sister Beth is living in San Francisco and working for and crushing on Robert Friars half-brother who suddenly goes missing. Rule gets some rather disconcerting news from Isen and why is ex-cop Drummond’s ghost still hanging around?

What a romp! Fast paced mystery that keeps you turning pages and staying up late.  Welcome to the world of the Lupi a mix of urban fantasy, mystery thriller, and paranormal romance.  You can’t beat it.
