Hammered - Book One

From Elizabeth Bear comes a near-future tale about a woman who was engineered for combat in a world that's running out of time. Jenny Casey is a former Canadian special forces warrior living on the hellish streets of Hartford, Connecticut, in the year 2062. Her artificially reconstructed body is failing her, but a government scientist from her old life thinks she is perfect for his high-stakes project.
Suddenly Jenny is a pawn in a battle being waged on the Internet, the streets, and in the complex wirings of her man-made nervous system. And she needs to gain control of the game before a brave new future spins completely out of control.
