Living an isolated life in a shadowed valley surrounded by mountains and a thick forest, a father and son are terrorized by a dangerous supernatural presence. Only the father's dark secrets can save them... or damn their souls for all eternity! Being a single father can be tough, but for Ezra Connolly, it's a duty he doesn't take lightly. Living off-grid, away from prying eyes, in the heart of forest country, he spends his days teaching his teenage son Wil survival skills. But Wil has questions, questions Ezra fears to answer-about his past, and about why they never leave the valley before sundown. Collects Blood Commandment #1-4.
