Arkangel: A Sigma Force Novel by James Rollins (Mass Market Paperback)

In Arkangel, the Sigma Force team faces a worldwide hunt in which old myths turn out to be rooted in fact. Rival nations race toward the same hidden prize, and the evidence points to a lost continent whose secrets could upset the balance of global power.

James Rollins sends his elite operatives from remote ruins to high-tech laboratories, mixing real history and cutting-edge science with the nonstop action his readers expect. Betrayals, close calls and a countdown keep the tension steady throughout.

This is the eighteenth Sigma Force book, but the story is built to be approachable, so thriller fans can jump in here and then work backward through the series.
