The Doomsday Key: A SIGMA Force Novel by James Rollins

3.0

Another fun thriller from Rollins that expertly and deftly combines interesting pieces from the historical record with modern science--and, of course, a healthy dose of guns, explosions, and intrigue. Small lesson learned: Reading two of the Sigma Force novels so close was probably not such a great idea. Although they are fun, reading one so soon after the other just made the formulaic nature of Rollins' novels quite glaring.
