Buckle up for a wild ride through three gripping thrillers

Meet the unlikely hero of the Decrypter series: a skeptical museum curator who's about to have her world turned upside down. When the British government tasks her with decoding an unbreakable script on an ancient manuscript, she never imagined the danger that awaited her - or the mystery of her own long-lost parents.

With the help of two loyal friends and her expert knowledge of history and technology, she embarks on a thrilling journey of cyber espionage, uncovering criminal plots, unexplained phenomena, and mind-bending science along the way.

The Decrypter books are heart-pumping action adventures that blend history, espionage, and cyber defense in a world that's becoming more digitally dependent by the day. Whether you read them in order or as standalone stories, get ready for non-stop action, nail-biting suspense, and a heroine you won't soon forget.

Unleash the adrenaline rush with this heart-pumping, page-turning thriller that fans of Steve Berry, Jason Bourne, Scott Mariani, Ernest Dempsey and Clive Cussler cannot miss!

This digital box set contains the first, second, and third thrillers.
Book 1- Secret of the Lost Manuscript:
 When a highly guarded, undecipherable document vanishes in Berlin, Calla Cress finds herself against an adversary with superior firepower. Calla must use her wits to decode the manuscript’s riddle before it’s too late.

Book 2 -The Mind Hacker: After an explosion rocks Calla Cress’s hideout in Colorado, she wakes up halfway across the world at the whim of a powerful, unidentified organization demanding she produces the whereabouts of a missing MI6 agent who can disarm a series of hacks snaking through one government system after another.

Book 3 – Digital Eyes Only: When the British Prime Minister’s private accounts are compromised, Calla Cress is called on to decrypt a mysterious cipher left in the Prime Minister’s home.

Excellent Follow Up

Fast paced with a mixture of action and sci fi. I would recommend this series.

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.

Can't put this story down.

Brilliant!!! Started with the decryptor and straight into the mind hacker. Gripping storyline.

Colin Ward
Action packed from start to finish

Thrillers with a bit of science fiction.
Although this is fiction it could become fact, think of Jules Verne, his fiction became fact.
A very good read.
