The secret of the manuscript is only the beginning . . . The truth could cost her life.

Calla Cress has been searching for her missing parents for her entire life. She thought the mystery was long buried, but when a two-thousand-year-old manuscript with an unbreakable code lands in her hands, she is suddenly thrust into a desperate race against time.

As the British Museum curator deciphers the cryptic message, she becomes the target of a secret government agency enemy determined to keep the truth hidden at all costs. When the manuscript vanishes in Berlin, Calla realizes that the key to her family's disappearance may be encoded in the ancient text.

With no time to lose, Calla, NSA security advisor Nash Shields, and tech entrepreneur Jack Kleve set off on a globe-trotting mission to decode the riddle and uncover a shocking technological breakthrough. But as she battles against skilled assassins and unravels the layers of deceit, she realizes that nothing in the modern or ancient world is as it seems.

As the clock ticks down, Calla must risk everything to solve the mystery of her missing parents and prevent a dangerous new world from being unleashed. This is a race against time that she cannot afford to lose.

Experience the rush of danger and the thrill of the chase in this thriller, perfect for fans of Ernest Dempsey, Jason Bourne, Steve Berry, Scott Mariani, and Clive Cussler.

A wonderful action novel full of surprises

This is an author I was unaware of but the subject matter was intriguing and it was free to download so I thought why not? I read the first 2 books back to back and really enjoyed. Anyone with an interest in ancient codes and archaeology will love these, Calla Cress is a bad ass with 2 best friends who, as underdogs, you find yourself rooting for. I look forward to reading the rest of the series.

There are so many things I liked about this book. First it's long and involved but there are no dry or boring sections. There are a lot of characters - Calla, Nash and Jack with Allegra. Details, without being wordy, clarify character descriptions, places, events, etc. While there is one main plot, there are several others around the main plot and eventually all are connected. I love the characters. The book is long enough you feel like you know them. There is mystery, theft, intrigue, and a bit of the supernatural. While I'm not much of a science fiction fan, this book did a great job of incorporating the 'out of this world' elements so I enjoyed the idea very much. There are other books in the series and I will be reading them all.

Good read

Intriguing good story

Really good, long read

his book is nothing like I expected. It has everything including great characters, story line and the unexpected. I thoroughly enjoyed it and have no hesitation in giving it five stars. I should add that this is a rare rating for me as I usually only give four stars as my highest

Great first read for an author I've not read before!

The Decrypter Secret of the Lost Manuscript got me hooked in the first few pages! Rose builds mystery and she weaves her own history for the story while getting to know Calla, her background and how they merge together. By the end, Im already looking for the next book in the series.
