The prophecy in Revelation declares that a quarter of the world must die …

… And now a shadowy organization has the ability to fulfill these words. Can one woman stop the abomination before it’s too late?

ISRAEL. A victim of Jerusalem Syndrome jumps to his death from the top of the Western Wall, his body smashed on the ancient stones. Another disembowels himself under the scrawled figure of the Pale Horse of the Apocalypse with the chilling words, “God told me to do it.”

Dr. Morgan Sierra travels to Israel to investigate the deaths and becomes embroiled in an international conspiracy that will use cutting-edge technology to carry an ancient curse to mankind, and threaten those she loves.

Morgan joins agent Jake Timber at ARKANE, a secret government agency investigating the supernatural. Together they must hunt down the Devil’s Bible, pursued all the way by the evil forces of Thanatos.

From the catacombs of Paris to the skeletal ossuaries of Sicily and the Czech Republic, Morgan and Jake must find the Devil’s Bible and stop the curse being released into the world before one in four are destroyed in the coming holocaust. Because in just seven days, the final curse will be spoken and the prophecy will be fulfilled.

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
