Reseda Juarez is dead. Though she functions as a human, inside she's an emotionless weapon, trapped between the living and the undead. Cold and unrelenting, she's used as a super-soldier by the government in a special task force to hunt preternatural beings to the brink of extinction. One night, five years ago, Kane killed an innocent and his brother lost the love of his life. The aftermath forces Kane to become the alpha of the legendary Thunderbirds. He now must protect what's left of his family from the tribe of wolf shifters who ripped them apart. When Reseda's mother is bitten by a wolf, she and Kane are forced to work together to find the Mayan Pul Yah stone to heal her—the same stone that gifted Reseda to the life she now lives. But the journey is riddled with more than wolves, also searching for the stone. Something strange happens to their powers when they're together, and they struggle to fight the intense attraction between them. The deeper they go, the more secrets unravel, until love is the only thing that can defeat an enemy no one saw coming.
