Classified. Hacked. Disaster.
Calla Cress didn’t want to know the future. Heck, the future can wait, but not when it’s wiped clean her present.
A scientist from an ancient world. A mathematician she adored. An app that is driving the world into limbo.
The Decrypter: The Pythagoras App is Book 5 in the Calla Cress Technothriller Series, but can be read as a stand-alone story.
