Like other Sigma Force novels, I could not put this one down. I also found it hard to go to sleep until I found out what happened to Painter, Gray, Monk, Kowalski and others. I love the historical details Rollins adds to his novels. Imagine if Rollins was my history teacher when I was a kid? I might have become a history major:-)

Yet another Sigma Force adventure. Getting closer and closer to finding out who the key Guild players are. This book had them traveling from D.C. to Italy, Norway, Scotland, Wales and the Lake District. Now I need to add Bardsey Island to my must-see list.

I love me some James rollins, but this one felt like the same plotline(s) as previous sigma force novels repackaged.

I can see why this is the one that’s on the cover of all the other books as “author of The Doomsday Key.” It’s just the perfect combination of sci fi and puzzle solving with a well-developed and interesting cast of characters, topped off with excellent pacing. I couldn’t put it down.

This was another fun (if more straightforward) adventure from James Rollins and Co.! I always secretly love when all his characters are involved in whatever mystery, and this was no exception! Deftly executing multiple subplots that weave together effortlessly at the end, Sigma scrambles to find the cure for a mysterious plague that could soon be unleashed upon humanity! New characters are introduced, new alliances are made, and war looms on the horizon. While I felt only *slightly* misled with this one, it nevertheless was an exceptional read that sets up an epic showdown yet to come!

Not as exciting as the other Sigma Force novels, but I thought the plot mystery was interesting. Good vacation read.

Another adventure with the gang.

This one was just blah in the overall series. The plot is familiar: overpopulation, but it did wonders to advance the Sigma character plot lines. I hope that the Guild begins to play a larger role in the novels as the war seems to be coming.
