Christopher Bentley

When a Saint Petersburg restaurant is torn apart by a devastating explosion, consulting mathematician Marc Naedorf is pulled back into the shadow world he thought he’d left behind.

Once an intelligence analyst, now an outsider with a gift for spotting hidden patterns, he finds himself at the heart of an international mystery where every answer raises new questions.

With espionage networks looming in the background, Naedorf follows a trail that winds from the Russian mafia to the boardrooms of multinational corporations. Superpowers are vying for quantum computing supremacy, cyber hackers are breaching global systems, and a covert conglomerate is manipulating markets through rogue AI and corporate conspiracy. From climate change profiteers to ruthless mercenaries, Naedorf must navigate a labyrinth of deception, where even allies can’t be trusted.


CONCERN is available in hardback, paperback and eBook through your favourite bookseller, online or on the high street. My author website, ChristopherBentleyAuthor.com, includes links to Amazon, Barnes & Noble, Apple Books and Waterstones.

HOWEVER, for the next few weeks, the eBook is available free of charge:
https://www.amazon.co.uk/Concern-blac...

The book is 364 pages long, and the beginning of a series featuring Marc Naedorf.

I'm very happy to interact with members of the Group, and to be considered for BOTM.

Thank you!

EDIT: Thanks to BA Rae for prompting me about USA availability (doh!). Here's the book on Amazon.com:

It is a bit much for a subtitle Christopher, but can understand the reasoning behind it.

Indeed, Lesle. Marketing considerations sometimes clash with artistic sensibilities, such as they are. At least the book cover itself has no subtitle. I don't think it needs one.

Christopher it probably is a good thing it is not on the cover.
