This was supposed to be brand new, but it's not. It had some marks on it. It could have been used as an old CD or cassette tape, not new.
Bad review

My cat loves these mice she likes the one that is a little bigger then the others. Would buy again if I ever have to but it seems like they aren't available in stores. Good buy. They don't hold up so long for her though because of how small these are.
Good Review

Didn't really hold my interest at all. Too contrived in my opinion. I'm a fan of most all books that have been written by Nora Roberts. I don't mind cliff hangers - but after reading one like this--well let's just say it was an unsatisfactory ending. The only thing redeeming about this, is the love between Bella and Edward. That's more of her usual writing.
