Publisher's Synopsis
"The deadliest secrets are the ones you can't see."
Caidin Wells, the Evolution Man, is no stranger to high-stakes operations, but this one cuts deeper than ever. Recruited to slip behind the Iron Curtain, his task is clear: help a brilliant Russian scientist defect before the Kremlin can claim his game-changing invention: the Ion Device, a machine capable of rendering its user completely invisible.
But when Caidin learns that the egotistical Randolph Devereux is involved, the stakes become far more personal. Devereux has his own deadly agenda, and at his side is Natasha Burke, Caidin's ex-lover, enhanced by the same technology, making her faster, stronger, and nearly unstoppable.
As the true power of the Ion Device is revealed, Caidin is thrust into a deadly game of espionage, where the line between friend and enemy blur, and the unseen is the greatest threat of all.
