UNDEAD UPRISING: Book 1 of the Villalobos Legacy

Werewolf v. Vampire. It's been a battle for centuries as the werewolves try to control the vampires who would like to wipe them out. Catalina is the heir to the Villalobos werewolf clan, but her path to leadership is challenged by the fact that she cannot control her werewolf self and is powerful even in her human form. To take up the reins of leadership, she must not only prove herself to her people, but survive a traitor in their midst who will betray her to the vampires.
