Publisher's Summary

A construction project beneath the National Mall reveals a dark secret dating back to the Civil War, something buried by a cabal of scientists, led by Alexander Graham Bell, who helped found the Smithsonian Institution. It is a cache of bones, preserved in amber, protecting a wonder like no other, the very secret of life after death. But such a prize is guarded by a horror out of the ancient past, a horror that still lives in the marrow of those bones - and is now free again.

From a crystalline lab atop Mount Fuji to an island off of Hawaii teeming with what's been called the "dark matter of life", Sigma Force must solve a mystery going back eons, to when life first took root on this planet. But the menace is spreading, changing, growing, adapting, outwitting every attempt to stop it. It means to retake a world it once ruled.

For Sigma Force to stop it, Commander Grayson Pierce will have to do the unthinkable: team up with Sigma's greatest enemy - the newly resurrected Guild - even it if means sacrificing one of their own.

another amazing masterpiece by Rollins yet again he has outdone himself. my only complaint is how short it was. all of his stories end much too soon.

Yet another Sigma Force drama

Rollins does great research, and Baskous always turns his words into real action. That said, the trials and tribulations of our friends in Sigma Force are starting to get repetitive, derivative and predictable. If not for the craft of Baskous, I would likely have turned off this series by now.
Recommended for fans of the series only.

Another Sigma special

I very much enjoy the Sigma Force novels and this one is no different. Rollins has perfected the art of blending historical facts, scientific facts, and a covert paramilitary organization in a way that keeps the pages turning. Parts of the book had me running to Google to fact check the information. While I'm fine with believing the entire thing, sometimes, the best lie has quite a bit of truth. Well done and well read. I look forward to the next.

Rollins does it again!

Well, Rollins has cost me another night of no sleep - but once I started listening to The Demon Crown there was very little chance I was going to take a break from it. To be honest, it's been a few books in the Sigma series since I've been "wowed" but this book did that for me. There is just not a place in the story where you can stop and take a breath - it just pulls you along and you just have to know what comes next. The research and detail is so well woven into the story it's not like "ok, we need to stop now for an info dump" - the story just keeps barreling on. Also, I think Christian does an incredible job with the audio - when he gets wound up during a high tension scene you can just feel it - something incredible is going to happen. One thing - I'm glad I listened to this when all the bugs outside aren't around (too dang cold) because I don't think I could have taken seeing a wasp - or even a mosquito. The only bad thing I can say is that I have to wait another year for the next Sigma book. Might have to go back and listen to some of my old favorites to give me my Rollins' Fix.

Interesting as Always

The plot is always as interesting as any of James Rollins’s other books. My only contention with this story was not in the plot or the characters but in the narrator. He did a good job, it just grates on me when I hear people mispronounce Hawaiian words. It is a pretty common thing so I try to let it slide. Just being a Kanaka Maoli myself it bother my ear to hear stuff pronounced wrong. That said, I found the info about the wasps interesting.

Awesome, again!

My favorite Rollins novel yet. Raced through it, and found myself repeating, "Wait, WHAT!" And, of course, Baskous knows how to make it real, right!

By telling the truth graham Bell was Scottish/U.K. like 90% of great inventors not AMERICAN so please just because he moved there don’t do what Americans seem to always do and wipe peoples heritage away
