Deep in the Rocky Mountains lives Ivy, a mysterious half-human, half-serpent woman whose blood is rumored to grant eternal life. When poachers close in, tribal hunter Kane recognizes her as the creature who saved his life fifteen years ago and vows to protect her.
Ivy tries to drive him away for his own safety, but Kane keeps coming back, and their wary bond slowly turns into love.
As poachers, rival tribes, and a dying billionaire send increasingly deadly forces after her, Ivy and Kane are forced to fight for each other, their people, and the right to build a life together in the mountains.
