Book Launch. Prophecy, An ARKANE Thriller

Today is the official launch of Prophecy, #2 in the ARKANE series of action-adventure thriller novels. It currently has 16 reviews averaging 4.5 stars on and has already made the Amazon bestseller lists in Action Adventure and Religious Fiction. I have a whole lot of launch posts coming which I’ll link to below but here’s the blurb and some reviews.

“I looked, and there before me was a pale horse. Its rider was named Death, and Hades was following close behind him. They were given power over a fourth of the earth to kill by sword, famine and plague, and by the wild beasts of the earth.” Revelation 6:8

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?

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.

Prophecy is now available on the Amazon Kindle store. Coming soon on other ebook platforms.

Praise for Prophecy

“Penn…has a background in theology and she employs this to great effect again in this novel. These books are as intelligent as they are gripping. She has also upped the supernatural ante since Pentecost and created a demonic villain (or two) that rise to the spiritual struggle inherent in the book’s premise. 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’

“The action moves swiftly but the suspense never wanes, as Penn uses her vast knowledge to inform and educate the reader in a seamless unfolding of this fast-moving tale. Exotic locations and supernatural artifacts add to the adventure. Pentecost has been described as Lara Croft meets Indiana Jones and there are certainly elements of both to be found in these thrillers. However, I feel Joanna Penn has managed to establish her own voice in this series delivering strong characters and creative, but believable, plots. I’m already in line for the next one!” Patricia Sands, on

“Penn has a degree in theology and her knowledge and research, of ideas and locations, really shines through in these stories…as rollicking thrillers these books are great – perfect for holiday reading.” Alan Baxter, dark fantasy author of Realmshift & Magesign

“Prophecy is 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. Mystery and adventure that is sure to please readers who love a good religious thriller.” David Wood, action-adventure author of Quest, Dourado and Cibola

“If you’re a fan of Dan Brown, then Joanna Penn is the author for you. Like 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, who also did a great video review here.

“I particularly like the main character, the strong, intelligent, and attractive Morgan Sierra. Joanna Penn uses her academic training in Theology and Psychology to weave an intriguing page-turner in which Morgan must locate an artifact and prevent the Apocalyptic prophecy. I love learning as I read, and this book did not disappoint me. Through it, I learned about the God Helmet, The Devil’s Bible, the ossuaries, and various art and architecture. Joanna Penn seamlessly interlaces the facts with the story, creating a wonderfully vibrant and compelling story.” Jane V Blanchard,

      Yes, the soft launch was just to existing fans and helped get some rankings and reviews on the board. This is the broader push. I think the algorithms respond to sales over time as well as spikes and I shall continue to play with different marketing approaches.
