The mountain is never helpless. It has Leo. And Leo has teeth.

Leo is the Sentinel of Shale Mountain, a wolf bound by ancient magic to protect the deep woods of North Georgia. But his feral instincts are pulling him further from his humanity, straining his tether to his husband, Austin. When the mountain begins to scream, Austin realizes the threat isn't just in Leo’s mind. It’s echoing from the valley below.

A powerful energy corporation has set its sights on the valley beneath Sentinel Gap, bringing plans for a massive hydroelectric dam that would drown miles of ancient forest beneath dark water. To the people in town, the project promises jobs, money, and a future. To Leo, it feels like a death sentence for the mountain he was born to protect.

As tensions rise across the valley, strange things begin happening deep in the woods. Wildlife vanishes. The earth trembles without warning. And something ancient buried beneath the ridges seems to be waking alongside the growing violence surrounding the project.

To save their home, Austin must dig through a century of buried history while Leo is forced to unleash the devastating, untamed beast he’s spent years trying to control. But fighting a modern empire will require more than paper trails and claws.

As the floodgates prepare to close, Leo and Austin must make a desperate stand against the concrete parasite threatening their home. In a battle between ancient magic and corporate greed, they will risk everything to protect their territory, their pack, and each other.
