After an exhausting trip to Europe, Lizzie and John come home wanting nothing more than peace and quiet. Instead, Lizzie finds a death threat on her pillow, and John must fight a challenger to his position as Texas Pack Alpha-and in his backyard. What will the neighbors think? Soon Lizzie and John find themselves fighting for their lives. But who is masterminding the attacks? Is it Lizzie's old arch-rival Worth? Or an even greater threat? And where is Lizzie and John's relationship headed now? Defensive Magic is third in the Lost Library (Paranormal Urban Fantasy) series, but can be enjoyed as a standalone novel.
