"The best word I can use to describe Battles's writing is addictive." (James Rollins, New York Times best-selling author)

From USA Today best-selling author Brett Battles comes a new electrifying adventure in his award winning Jonathan Quinn thriller series.

A snowy night. A train making its way through the mountains of Austria.

Asleep in one of the private compartments is a very important passenger, a scientist who has created something others desperately want.

Precautions have been taken to ensure the man's safe passage, but even with a highly skilled bodyguard onboard, the trip does not go as planned.

When the scientist vanishes, Jonathan Quinn and his team are sent in to locate him before the secrets in the man's head can be extracted. Because if that happens, the world would change forever.
