A riveting near-future thriller. From the NY Times bestselling author whose books have sold over a million copies.

An alien object with breathtaking capabilities. And a life-and-death struggle for the future of humanity.

Dr. Kelly Connolly is part of a top-secret team studying the most important find in human history, the Enigma Cube, an alien artifact of incomprehensible power. A cube whose technology can catapult civilization to dizzying heights–or destroy it entirely.

After years of failed attempts to unlock the cube’s secrets, all hell suddenly breaks loose. Kelly and a black-ops commando, Justin Boyd, are soon fighting against all odds to stay alive, and to keep the cube out of enemy hands.

As the situation quickly goes from bad to worse, Kelly discovers that the cube’s capabilities are far greater than even she had imagined. And that her actions could lead to nightmarish changes to the nature of reality itself.

The Enigma Cube is a smart thriller crammed with breakneck action, unexpected twists, mind-blowing science, and ethical dilemmas readers will be contemplating long after they’ve read the last page.
