Decrypter - Digital Eyes Only

Encrypted. Stolen, Ransom
A hi-tech encrypted device, with a list of codes detailing far-future technologies, goes missing from the NSA's vault of secrets.
When the British prime minister's private accounts are hacked, museum curator-turned-cyber-defense agent Calla Cress is called on to decrypt a mysterious cipher left in the prime minister's home. Soon a series of encrypted ciphers surfaces on a darknet site, the Vault, whose inception is steeped in the mysterious history of the Maltese Knights. As Calla gets closer to not only unearthing the Vault's interlaced web of secrets but also discovering the identities of the darknet masters, she learns that technologies aren't the only thing the darknet intends to auction.
Calla has no idea how far the quest will plunge her and NSA agent, Nash Shields, into the past, and how much preventing a cyber war will hold the world ransom at a price much higher than she's willing to pay.
In a fast-paced, cyber-espionage, technothriller from the streets of London to the coves of Malta, from the glitzy allure of Monte Carlo to Spain's royal complex of the Alhambra fortress, Calla must end the sale of the NSA list, but with every attempt at annihilating the digital auctions, she risks exposing her dearest secret.
The Decrypter: Digital Eyes Only is Book 3 in the Calla Cress Technothriller Series, but can be read as a stand-alone story.
