Set in 2076, when all Earth is ruled by one government. The tenuous peace is held together by the iron hand of UN troops. As July 4th approaches, the Unification prepares for riots when Occupied America celebrates its Tricentennial. Denice and David Castanaveras are genetically modified twins who are swept up in the events surrounding the conflict. A pretty believable futuristic setting, good character development, nifty advanced technology and occasional humor.
