A J.F. Penn Storyworld

Death Valley

Above, the storm. Below, the dead.

The story

A luxury eco-resort sealed inside a monster sandstorm, where every secret becomes another way to die.

Death Valley is the perfect place to disappear. Until the desert refuses to let you leave.

After a child died on a caving trip under her care, British adventure guide Casey Thornton fled to the widest sky she could find: the Desert Sanctuary, a luxury eco-resort where the wealthy buy wilderness without danger.

Then a colossal sandstorm seals the resort off from the world.

Inside, every guest is hiding something: a billionaire transfusing young blood in his war against ageing, an influencer ready to turn protest into sabotage, a celebrity hunter with a crate he should never have opened, and a head of security preparing for civilisation's collapse.

As the glass dome fractures and fire races through the hotel, a child vanishes into the storm, and Casey must lead her towards the only shelter left. The tunnels below.

“The desert does not care for your wealth or status. It will transform you, or it will destroy you. The choice is not yours to make.”From Death Valley · the Timbisha artist's plaque

For readers of The Island, The Drift, and the elite destination intrigue of The Club.

Questions

Before you begin

Is Death Valley a standalone?
Yes. It is a complete story over one storm-sealed night, with a closed, redemptive ending.
Is it supernatural?
No. The imagery is gothic, with an ossuary crypt and ravens on the wind, but every threat in the book is human or natural. Readers who want the supernatural should step into the ARKANE thrillers instead.
What formats can I read it in?
Ebook (Kindle and Kindle Unlimited), paperback, a foiled hardback, large print, and audiobook. It is also available in German as Death Valley Feuersturm.
Is it connected to J.F. Penn's other books?
No shared characters, but it completes a set of standalone thrillers about nature refusing to be owned: Blood Vintage in the English vines, Catacomb beneath Edinburgh, Bones of the Deep on the open ocean, and Death Valley in the hottest place on Earth.
