A construction project under the National Mall reveals a dark key dating back again to the Civil War, something buried with a cabal of scientists, led by Alexander Graham Bell, who helped found the Smithsonian Institution. It really is a cache of bone fragments, conserved in amber, protecting a wonder like no other, the very key of existence after death. But such a reward is usually guarded with a horror from the historic past, a horror that still lives in the marrow of those bones-and is now free again. From a crystalline laboratory atop Support Fuji for an island off of Hawaii teeming with what’s been called the “dark matter of lifestyle,” Sigma Push must solve a secret going back eons, to when lifestyle first took root on this globe. However the menace can be spreading, changing, growing, adapting, outwitting every attempt to prevent it. This means to retake a world it once ruled. For Sigma Power to stop it, Commander Grayson Pierce will have to perform the unthinkable: synergy with Sigma’s most significant enemy-the recently resurrected Guild–even it if means compromising one of their own.
