Jacob Carter built his life around one vow: never be helpless again.

As a Navy SEAL, fear is buried under discipline, muscle, and mission. He runs toward danger, protects the weak, and survives what breaks other men.

Then an admiral forces him into Project 157.

The experiment tears him through the hull of a weaponless ship and strips away everything he mistook for strength. Jacob wakes in a spiritual dimension where none of his training can save him.

His weapons are gone. Everything he trusted in is a distant memory. And here?

Here, he is the hunted.

Here the darkness has teeth.

The lions can smell his weakness, and they obey only their relentless hunger.

Back on Earth, nurse Sage Emerson fights to keep Jacob’s body alive while the project studies the strange form of radiation that’s infecting her too. To them, he’s a super soldier with no soul, but she can’t let them turn him into a weapon. He deserves to come back from this, and she’ll do anything to make sure he does.

The admiral wants data.

The One World Government wants a weapon.

But Jacob is facing something older than science, closer than breath, and hungry enough to follow him back.

Plunged is a gripping Christian sci-fi thriller where military conspiracy and spiritual warfare collide.
