Crown of Demons is a narrative novel full of adventure and action, another story of the Sigma Force Special
When a team of scientists stumble upon an island off the coast of Brazil where all life has been destroyed and devoured by some unknown species beyond the wildest imagination, gunmen attack and kill all but one member of the team: entomologist and venomous animal expert Ken Matusui. But the threat is also linked to a terrifying secret buried under the National Mall a century ago: a collection of bones preserved in amber. The object was hidden by a group of scientists led by Alexander Graham Bell to protect humanity. At the same time, she did not dare to destroy it, for the object holds great promise for the future: the key to the mystery of life after life.
But the problem is far more frightening - an ancient horror has been unleashed in the form of a weapon of unspeakable power. Commander Grayson Perce of Sigma Force must stop this threat, but it's not easy. With each new discovery, the threat transforms and grows - adapting and surviving every attempt to destroy it. He's stronger and smarter every time. Running out of time and options, Gray decides to team up with Sigma Force's greatest adversary - the newly resurrected Brotherhood.
