Chameleon Assassin — B.R. Kingsolver

Libby is a mutant, one of the top burglars and assassins in the world. For a price, she caters to executives' secret desires. Eliminate your corporate rival? Deliver a priceless art masterpiece or necklace? Hack into another corporation's network? Libby's your girl. Climate change met nuclear war, and humanity lost. The corporations stepped in, stripping governments of power. Civilization didn't end, but it became less civilized. There are few rules as corporations jockey for position and control of assets and markets. In the year 2200, the world has barely recovered the level of technology that existed before the ice melted and the subsequent wars. The corporate elite live in their walled estates and skyscraper apartments while the majority of humanity supplies their luxuries. On the bottom level, the mutants, the poor, and the criminals scramble every day just to survive.
