Unholy Blood: A Horror Novel

By Ian Gielen

A hidden cave. A Halloween party. A nightmare waiting to unfold.

While exploring off-trail on Coon Mountain in the breathtaking Adirondacks, college seniors Jack and Mason stumble upon a mysterious cave, concealed behind a curtain of tangled vines. Excited by the discovery, they return days later with their friends for a once-in-a-lifetime private Halloween party in its shadowy depths.

But beyond the laughter, booming music, and crackling campfire, something stirs. Something ancient. Something ravenous. Their arrival has awakened a presence that has waited in the shadows for years-hungry for its favorite meal.

This Halloween, the party ends when the screaming starts.
