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.

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.

Not one of his best, made worse by narrator

What did you like best about The Demon Crown? What did you like least?

Fast moving, lots of interesting science. Narration was hideous, I can't understand why they keep hiring the same person to read

How could the performance have been better?

His attempts at accents and different voices is very weak, but what bothers me most is everything sounds like the characters are amazed at even trivial conversations. I keep telling myself I won't buy another book narrated by Christian Baskous.
