This book quickly drew me back into the Cyborg world. I had wondered after someone said something about how Hellfire would have been dead since it had been so long how her and Blackie would end up together. I really didn't expect the reason: that she's not completely human, but part of a genetically altered canine unit that the labs created at the same time they created cyborgs. This book ended up being less angst than I really expected, given the whole betrayed by allies thing. I was really glad that only a few of the cyborgs knew about the canine units (who were all female and that could have really helped with the early creation of the cyborg society, since so few of their women made it off Earth). I'm kind of expecting more canines to pop up in later books, despite the whole we are the only two left thing. I guess we'll have to see.
