by Rose Sandy (Author) Format: Kindle Edition
4.3 out of 5 stars 14 ratings

Predicting the future was supposed to be a game, until it became deadly serious.

When a perilous new app starts predicting the future and users begin falling into mysterious comas, Calla Cress, a secret government agent known for her code-cracking skills, is pulled back into a world filled with secrets and deceit. Racing against time to neutralize the app, Calla is confronted by a formidable adversary from her past who not only wields groundbreaking technology but also threatens to unveil a dark chapter of her life.

From the historic shores of Turkey to the captivating streets of Havana, Calla embarks on a globe-trotting quest to solve a centuries-old mystery linked to a disciple of Pythagoras. What starts as a technological anomaly soon unravels into a terrifying global conspiracy, challenging everything Calla thought she knew.

Dive into this exhilarating adventure where ancient secrets collide with modern technology!

Ideal for fans of Steve Berry, Scott Mariani, Ernest Dempsey, and Clive Cussler, The Decrypter and The Pythagoras Clause offers a thrilling blend of action, suspense, and historical mystery. Join Calla Cress as she navigates a labyrinth of espionage to stop a catastrophic future foretold by the past.

Prepare yourself for a heart-pounding journey that challenges the boundaries of time and technology, where every clue brings Calla closer to a truth that could change the world.

    Reviewed in the United States on December 24, 2020
    I have read all the books in this series and this one just adds to the depth of the characters. I also like the premise that an app is able to influence the lives of the people using it( sounds true to life). It is interesting how past and future is interwoven to come up to present day situations and link in to a whole situation. The different characters are developing and filling in their past experiences and how they are all now linked. I enjoy the Worldwide locations and some of the details given about them. I would buy this if you want an old fashioned rollicking adventure with a modern day twist.

    I've really enjoyed reading the 5 book Decrypter series! This last one was no less captivating.
    My only negative would be this last one left me hanging with the expectation of another story to find out what happens to one of the main characters. All the others were separate books and didn't rely on reading another story to find out what happens.
