Some doors in Afghanistan were built to keep armies out. This one was built to keep something in.

Summer, 1933

When antiquities scholar Nathan Harrow’s wife, Eveline, vanishes during a research tour in the rugged wilds of western Afghanistan, the official report from the consulate tells him it was a bandit attack with no survivors.

But Eveline has come home, or something wearing her face has. She stands beneath Nathan’s balcony, silent and shivering, her voice carrying a hollow resonance that isn’t her own. Her message is a plea: Don't come looking for me.

But driven by a guilt he can’t outrun, Nathan ignores the warning.

Partnering with Jack Delaney, a cynical American adventurer with his own shadowed past, Nathan strikes out through the Khyber Pass, a land where time itself feels fractured. In the mountain villages, names are forgotten mid-sentence, and the locals watch the horizon with a vacant, terrifying patience.

They call it the Shekahr.

It is an ancient hunger that feeds on suffering. It finds the "soft parts" of a man; the grief, the secrets, the unconfessed sins, and feeds until the body is nothing but an empty shell.

Eveline is still out there, trapped in a mountain fortress where the Shekahr keeps memories as trophies and pain is the only key. To save her, Nathan must face the one wound he has never dared to name.

The Shekahr has already tasted his fear and regret. And now, it’s inviting him in for the feast.
