To save mankind's future, the members of Sigma Force must make a devil's bargain as they join forces with their most hated enemy to stop an ancient threat in this gripping adventure from James Rollins. 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 find, a mysterious agency attacks the group, killing them all, save one: an entomologist, 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.
