Turning rogue without rhyme or reason, immortal predators are stalking human prey. If the outbreak of violence continues, their hidden society risks exposure to humankind. As the original werewolf, Aidan has a responsibility to stop the carnage. But as an alpha without a pack to ground him, his near-feral wolf borders on becoming the very thing he's attempting to eradicate. Finding Lucy-his fated mate-working with their enemy might prove the tipping point. A newly awakened Elemental, Lucy is thrust into the war between the immortals and an organization that wants them dead. When the ties to her past thwart the promise of her future, she must choose between her lingering loyalty to Citizens or the man she's fallen for. Neither can deny the fiery desire that burns between them, but will it be enough to save Aidan-and his wolves-from disaster?
