Two billion people are about to die… and they’re the lucky ones.
When a man in a hospital gown jumps to his death from the Western Wall in Israel, the authorities think it’s just another victim of Jerusalem Syndrome: a religious psychosis triggered by a visit to the holy city.
But when a second victim ritually disembowels himself, it’s the sign of much worse to come. Thanatos — a fanatical group dedicated to the destruction of the world — is on the move again.
The only ones who can stop them are ex-Israeli military psychologist, Oxford professor, and religious expert Morgan Sierra; and Jake Timber, agent of ARKANE, the British agency tasked with investigating — and sometimes saving the world from — the supernatural.
Last time, Morgan and Jake worked together to stop Thanatos from bringing about a dark version of Pentecost. This time, Thanatos is mixing science with sacrilege — combining the Devil’s Bible with mind-control technology to murder a quarter of the human race.
Together, Morgan and Jake will travel from the hallowed halls of Oxford, to the labs of a biotech company with a dark agenda, to a chapel made of human bones. They’ll go anywhere, do anything, to stop Thanatos.
But they have to hurry. Thanatos is on the rise. Apocalypse is at the gates. And the only way to save a quarter of the world is for Morgan to uncover the secrets of her past… at the cost of her own future. Death awaits in a Crypt of Bone.

Reviews
“The final showdown between Morgan and the forces of evil will stay with you long after you have finished this compelling, page-turning thriller.” – Orna Ross, author of ‘After The Rising’
“a gripping tale, plunging the reader into a race against a shadowy organization and its doomsday plot. Death lurks around every corner as Morgan Sierra and her partner Jake explore ancient ossuaries and dark catacombs in search of a sinister and deadly artifact.” – David Wood, action-adventure author of ‘Quest’, ‘Dourado’ and ‘Cibola’
“Like Dan Brown, Penn weaves information about religious art, icons and history with modern-day fears. The result is a face paced read, one that kept me up past my bedtime because I wanted to know what happens next.” – Natalie Wright
“I particularly like the main character, the strong, intelligent, and attractive Morgan Sierra … I love learning as I read, and this book did not disappoint me … Penn seamlessly interlaces the facts with the story, creating a wonderfully vibrant and compelling story.” – Jane V Blanchard
“Years ago Daniel Silva raised the bar in the thriller genre to include serious art references. James Rollins raised the bar to include real science applied in believable ways. And Steve Berry raised the bar to include serious historical and travel elements. The bar has been raised again. Ms. Penn brings all three elements into her thriller by combining her considerable knowledge of theology, her passion for psychology and science, and a deep appreciation for art.” – Seeley James
“Non-stop action thriller laced with fact and fiction. JF Penn writes with a style that is poetic and easy to understand. LOVED IT!!!!” – Dennis Barron
“J.F. Penn delivers again in this riveting, fast-paced thriller. Penn has an uncanny ability to transport the reader to exotic locales, providing stirring visual descriptions and a highly evocative sense of “place.” The action sequences and building suspense complement the emotional arc of Morgan’s journey, providing multiple layers for the reader to enjoy. A thriller that has no brake pedal, [Crypt of Bone] twists, turns, tantalizes, and leaves you breathless for even more adventures to come!” – Eric Praschan
“It’s a very well written action thriller with believable characters and the authors historical research into the various settings really helps set the scenes in your mind. If you are looking for a fast-paced Indiana Jones type adventure I would highly recommend… [Crypt of Bone].” – Scott Aday
“Penn’s style of writing can only be compared to Brown and Rollins. The ARKANE adventures remind me of SIGMA adventures, and Penn’s ability to illustrate the historical backdrops makes you feel like you are in the story yourself. This is a gifted author, an amazing story, and I highly recommend all of her masterpieces!” – Lisa Biegel
