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.

Releasing Soon!
