Relics of the Wolf by Lindsay Buroker

When Luna decided to reclaim her werewolf heritage, she had no idea what she was in for.

Frustrated, angry, and betrayed, she must find the mysterious artifact she lost, unravel the politics of the pack, and defend against attempts on her life.
With everything intertwined, she has a daunting road ahead, and her conflicting feelings about the lone werewolf, Duncan, aren’t helping anything. She doubts she can trust him, no matter how charming he is, but she may need to if she wants to get to the bottom of her troubles—and survive the week.
