Publisher's Summary

At Princeton University, a famed geneticist dies inside a biohazard lab. In Rome, a Vatican archaeologist is found dead in St. Peter's Basilica. In Africa, a U.S. senator's son is slain outside a Red Cross camp. The three murders on three continents bear a horrifying connection: all the victims are marked by a Druidic pagan cross burned into their flesh. The bizarre murders thrust Commander Gray Pierce and Sigma Force into a race against time to solve a riddle going back centuries and to a ghastly crime against humanity hidden within a cryptic medieval codex.
Aided by two women from his past, one his ex-lover, the other his new partner, Gray must piece together the horrifying truth. But the revelations come at a high cost, and to save the future, Gray will have to sacrifice one of the women at his side.
That alone might not be enough, as the true path to salvation is revealed in a dark prophecy of doom. The ultimate nightmare is locked within a talisman buried by a dead saint, an ancient artifact known as the Doomsday Key.

mystery - history storys

I wasn't sure what I was going to get into with this one and was pleasantly surprised. For a story based on pre-history up to the present it was really interesting and suspensful. This may not be for everyone but I enjoyed it. I mainly prefer espionage novels but would like to see-hear more of this.

Another Sigma Force Adventure...

Like Indiana Jones these stories are a romp on the wildside with great characters doing incredible things...yet through character development and a fast paced storyline you believe in their adventures...and are always routing for the good guy. The weaving of religion, science, technology, history and friendship is always a fine creation by Rollins and Doomsday Key is no different. Narrator was spot on and made the book come alive!

Although Rollins books don't have to be read in order it is beneficial to read them in order because you understand the characters and their sub plots. This series focuses on a secret goverment team called the Sigma Force. Each book describes a different "mission" they are enlisted in. The books cover a short period of 48 to 72 hours of the mission which usually takes place in several locations. The next book can be 6 months or a year later. It is a fun and energetic read!
