Hammered by Elizabet Bear (Jenny Casey 1)

Jenny Casey is hiding from herself and the Canadian authorities in former USA. She is half metal since a war accident, now her metal half is acting up. And now her former handler wants her back so he sends her whacked out sister.

Mix in an escaped AI and new technologies derived from alien space ships found on Mars and you have a very down to earth Space Opera.

Jenny might be the only one that has the reaction time and the wiring to handle the new tech. But she will have to work for people she hates again and suffer another set of operations to replace her failing prophesies.

It is much better than the cover.
