He drove north to find his father. He found a monster who made him tea.

Landon Walker and his brother Caleb were never just sons. They were subjects.

A rogue geneticist. A program designed to open the mind to the spiritual plane. A binding coded into their very genes.

Now their father wants to explain. And every answer is worse than the last.

Can brotherhood survive a betrayal that began before birth?

A charismatic predator is rising from the shadows to reclaim what she built. Her operatives are already closing in.

When the angel falls silent, where do you turn?

Two brothers. A dark inheritance. A nationwide conspiracy.

Faith says they were loved into existence. Science says they were manufactured. The enemy says they belong to him.

Not everyone will survive the truth.

Ipsum Esse is the eighth book in The Unfallen, a fast-paced Christian supernatural thriller series where spiritual warfare meets edge-of-your-seat suspense. Ancient evil. Campus conspiracies. Brothers forged in fire and bound by something stronger than genetics. If you love Frank Peretti's This Present Darkness, the theological depth of Ted Dekker, or the relentless pacing of Lynette Eason and Colleen Coble, Landon Walker's story will keep you turning pages long past midnight. The X-Files meets The Chosen.
