He was trained to fight enemies he could see. Now he's the only man standing between this world and the darkness behind it.

Navy SEAL Jacob Carter has always trusted strength, strategy, and steel nerves. But when a classified experiment called Project 157 tears open more than physics can explain, Jacob is ripped out of the world he knows and thrown into a realm where evil is no longer hidden.

It has teeth.

It has a plan.

And it already knows his name.

Back home, nurse Sage Emmerson is drawn into the wreckage of the experiment, where government secrets, impossible disappearances, and a growing spiritual darkness point to one terrifying truth: the war Jacob stumbled into was never an accident.

It was calling for him.

As Project 157 closes in and unseen forces tighten their grip, Jacob must face the one battle no amount of training can win. To save Sage, expose the truth, and stand against an enemy older than mankind, he will have to become more than a soldier.

He will have to believe.

Because the world does not need another weapon.

It needs a man of faith who refuses to bow.

Plunged is a gripping Christian sci-fi thriller packed with spiritual warfare, high-stakes action, hidden agendas, and the kind of faith that turns ordinary men into weapons of Heaven.
