The book this is a sequel to, Silver Metal Lover, is a favorite, and I'm afraid Metallic Love suffered from the comparison, especially having reread Silver Metal Lover just before this one, and falling in love with it all over again. Tanith Lee is a favorite writer of mine--she tends to write lyrically and lushly, and several books, including this one, are written first person, usually from a very fresh, distinctive individual voice--the protagonist of Don't Bite the Sun, for instance, sounding nothing like Jane of Sliver Metal Lover, and I'm usually immediately sucked into the book.
That wasn't the case with Metallic Love. It's protagonist, Loren, didn't engage me the way Jane did, and I kept reading only because of the connection with the other book. Among other things, I wanted to see if Jane showed up. This is set only twelve years after the events of the first book, which has been published underground as Jane's Book and made a huge impression on Loren as a child. She's constantly quoting from that first book, and it's jarring and intrusive, as if what I'm reading is not very good fan fiction. Fan fiction from someone not really a fan, who is trying to subvert and belittle the original. Indeed at first it seemed to be trying to completely invalidate the original, blot it out, and I hated the book for it. And being constantly reminded of that first book wasn't to the advantage of this one, which might have stood up better on its own as a completely independent narrative.
Eventually I found that wasn't really so. Nevertheless, I don't think this book has the magic of the first. It's a very, very different story. Silver Metal Lover is the story of a vulnerable teenage girl in the throes of first love. It's about her coming into her own identity through love, and though the book leaves open how much Jane is reading into her lover what she wants, it's still basically a lovely, touching romance. A Romeo and Juliet. This book, on the other hand, is Frankenstein. Verlis, the robot lover, is far, far less likeable and approachable than Silver of the first book--rather sinister in fact.
Metallic Love is imaginative and well-written, which is why I'm giving it as high as two stars, even though I'd feel, at the very least, ambivalent about recommending it to those who loved Sliver Metal Lover. (Although by and by, this book, though set in North America, is riddled with such Briticisms as "lift," "fancies" and "shags" I didn't notice in the first book--possibly an editing issue). With Tanith Lee you can take beautiful prose and strong world-building for granted, and this book did feature a neat twist at the end. After having finished the novel, I don't wish, as I had a third way through, that Lee had never wrote it nor I had never read it. It doesn't take away in the end my love for the first book, but neither does it add to it. And this will be the first Tanith Lee book I've owned that won't be staying much longer on my bookshelf, but will find itself purged the next time I have to winnow my collection. While Silver Metal Lover will have to be pried out of my cold, dead hands.
