Unfortunately this book is my must hate book of 2010. If I didn't have an ereader, this book would have hit the wall at great speed.
I thought the "hero" was an absolutely heartless, unromantic, horrible creature. He treated the heroine badly and I couldn't find any romance in this book at all. I did read it till the end and in my eyes the hero did not redeem himself in any way whatsoever. He was horrible right to the end.
I've loved all this author's books (love the Zorn series and her others, other than the cyborg books which I haven't read at all at this time after hating this book so much) so I was quite shocked that she would produce a hero such as this. In all her other books I've read, the hero has treated his heroine like gold so I expected the same here - not so; bad, bad, bad hero.
I've been assured by another reader that the other cyborg books are okay, that this hero is the only jerk, so I'll go check out the rest now in the hopes that I can love those books. I don't think I'll read Iron's book though, he was such a b*stard in this book, I don't want to know about him.
But this one, sorry author, but no!
EDITED TO ADD: See Mamimi's review - she said it so well, my feelings exactly! (unfortunately after I put this here her review disappeared - a pity because it was one of the best reviews I've ever read - she expressed my revulsion for this book so perfectly)
I have never gone back to read these Cyborg books - can't do it after this one. Her New Species are wonderful and just what I expect from this author - this one ... just no.
