The Demon Crown (Sigma Force, Book 13)

Off the coast of Brazil, a team of scientists discovers a horror like no other, an island where all life has been eradicated, consumed and possessed by a species beyond imagination. Before they can report their discovery, a mysterious agency attacks the group, killing them all, save one, an entomologist, an expert on venomous creatures, Professor Ken Matsui from Cornell University. Strangest of all, this inexplicable threat traces back to a terrifying secret buried a century ago beneath the National Mall: a cache of bones preserved in amber. The artifact was hidden away by a cabal of scientists―led by Alexander Graham Bell―to protect humankind. But they dared not destroy it, for the object also holds an astonishing promise for the future: the very secret of life after death. Yet, nothing stays buried forever. An ancient horror―dormant in the marrow of those preserved bones―is free once more, nursed and developed into a weapon of incalculable strength and malignancy, ready to wreak havoc on an unsuspecting world.
