Broken Bonds. The Lizzie Grace Series, #8

The winds of change are finally whispering through the Faelan Werewolf Reservation. Lizzie Grace is doing her utmost to ignore the portents of doom, wanting nothing more than enjoy her life and her time with Aiden O'Connor while she still can. But the song of the once unprotected and very powerful wellspring still washes across the distant shores of darkness, and it continues to draw evil to the reservation. The one that arrives this time is different from the others.
Not only is it skilled in magic, but its kills are very specific. Very targeted. As the brutal deaths mount up and she, Monty, and Aiden struggle to find answers and stop the killings, Lizzie begins to suspect there's more to this particular evil than meets the eye. Especially when it helps save the life of a child. But the biggest threat to Lizzie comes not in the form of evil, but rather the changes whispered on the wind. Because the werewolf Aiden once asked to be his wife has finally arrived back in the reservation. And she's determined to get her man.
