“I simply could not put this book down: gripping, exciting, dangerous, nail-biting … But perhaps what I loved most is Mackley’s depiction of Paris in all its smells, colours, corners, lights. His writing is like the still life painting of a Dutch Master where every texture is front of your eyes, mixed with the energy of a Van Gogh.”

Zoe Jasko, author of What the Wind Saw and Hope is Daffodil Bright, review on her Facebook author page

​

“This is an interesting premise - mostly a straight up adventure thriller told from first person, present tense narration. But as the story unfolds, it has an edge of paranormal and perhaps what could even have been hints of horror. The author ultimately steers clear of this and it ends on the thriller note more than paranormal, but there is is still an edge. Do we take the characters at their word or go down the hinted path? This rating will probably fluctuate a little as I let the story sink in. But 4 (4.25?) will do for now.”

Charlene Mattson, author of The Fairy Tale Case Files and Once upon a Midnight Dreary, review on Goodreads

​

“After reading the blurb, I knew this book would be right up my street, and it did not disappoint. It took me back to reading a Dan Brown or Sam Bourne story with all the adventure the ancient codex brings. There was certainly some twists and turns that I did not see coming in the story, and left me with my mouth hanging open! It kept me on my toes, with a good pace throughout.

Jon brings Paris to life in his writing and throughout he writes in an easy to follow style. However there is some French thrown in there, but I was able to use the translate feature in kindle.”
