Mortal Ties (World of the Lupi #9)

Eileen Wilks' novels of the Lupi have drawn readers into a seductive world of action, suspense, and passion. Now, FBI agent Lily Yu tracks a traitor into the darkest shadows yet… 

FBI agent Lily Yu is living at Nokolai Clanhome with her fiancé, lupi Rule Turner, when an intruder penetrates their territory, stealing the prototpye of a magical device the clan hopes will be worth a fortune--if a few bugs can be worked out . . . 

But the protoytpe can be dangerously erratic, discharging a bizarre form of mind magic—and it looks like the thief wants it for that very side effect. Worse, whoever stole the device didn’t learn about it by accident. There’s a Nokolai traitor in their midst. Lily and Rule have to find the traitor, the thief, and the prototype. One job proves easy when the thief calls them--and his identity rocks Rule’s world.  

As they race to recover their missing property, they find Robert Friar’s sticky footprints all over the place. Robert Friar--killer, madman, and acolyte of the Old One the lupi are at war with--an Old One whose power is almost as vast as her ambition to rock the entire world . . .
