Perfect for you if...

  • You enjoy historical thrillers that blend real figures with speculative secrets, like Dan Brown but grounded in actual academic intrigue.
  • You're drawn to puzzles embedded in old texts and want a protagonist who solves mysteries through research, not just action.
  • You like romance as a subplot rather than the main event, especially when it's between characters with genuine chemistry under pressure.

Maybe not for you if...

  • You prefer straightforward heists or spy stories without the historical deep dives and academic tangents.
  • You want graphic violence or dark psychological horror—this is a page-turner, not a gutting thriller.
  • You're sceptical of magic systems in otherwise grounded thrillers and need hard science fiction logic.

About this book

Isaac Newton kept a secret so dark, he took it to the grave. Now his secret is out… and people are dying. Historian Trina Piper is called to the British Library to authenticate a manuscript that could change history—a document believed to have been penned by the legendary Isaac Newton. As she dives deeper into the text, the body count rises as an ancient threat plagues London once more. When a mysterious scholar appears, determined to take the manuscript for himself, Trina considers it a minor annoyance… until she discovers the truth: he’s part of a shadowy Order bent on reviving forgotten magic for sinister purposes. And now Trina is forced to confront questions her academic training can’t even fathom: Can science and magic coexist? Should they even try? With the help of a handsome and resourceful Interpol agent, Trina must navigate a treacherous web of ancient secrets and deadly conspiracies, taking her from the fog-shrouded alleys of Westminster to the hallowed halls of Cambridge University. Buried within the pages of Newton’s cryptic work is the answer she seeks—if she can decipher its three-hundred year old message in time.As Big Ben ticks down, Trina must reconcile two seemingly contradictory facts: not only was Sir Isaac Newton first among modern scientists, he was also the last of the medieval alchemists…And his long-buried secret could spell the end for them all. Join Trina Piper in a dual-timeline, lost artifact historical mystery series that will take you from London to Paris to Vienna and beyond! It all starts with book one, The Newton Cipher.
