When an elite group of international scientists disappears from a classified facility on a remote Pacific island, Calla is deployed alongside an ex-Marine intelligence officer and a genius engineer to find them. What they discover defies every assumption about what is possible, and what should never have been built. Calla races to stop a weapon that does not fire bullets. It controls storms.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eLocations: Hawaii, St. Petersburg, Miami, Atlantic coast of Portugal\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eBook 5: The Pythagoras Clause\u003c\/h3\u003e\n\u003cp\u003eYou download the app. It predicts your future.

They lead to something far more dangerous. Then the cave collapses. Jack vanishes. And Calla is named the prime suspect in his disappearance.
