Query: Technological and Polticial Revolutions Well-Handled

This excellent book places the discovery of revolutionary technology against the backdrop of a Martian independence movement. Bear is a master of hard-core science fiction, but he also succeeds in the challenging task of telling the book from the point of view of a member of the opposite sex. There are hints of Eon here, in people's desire and ability to "enhance" and "transform".
