This is the second volume in a trilogy and exemplifies why I have such a poor track record with series and why I flatly refuse to even think of writing a series myself. The problem is that, with some rare and treasured exceptions, the second volume must of necessity be a repeat of the first, because it's all you have. Yes, you can bring in new characters, but you're still stuck with the same original character you're writing about, who is going to do largely the same things. It's boring, lazy, and uninventive, and I don't feel that ought to be rewarded.
I really enjoyed Crystal Singer, the first volume, which is why I moved on to the second one, but here's where it predictably fell apart. I should have quit after volume 1! Killashandra is a crystal singer - or cutter. She 'mines' crystal by cutting it with a sonic knife on a cliff face, and in the first novel she found herself a nice claim which had a vein of black crystal. So valuable was it that she got to visit another planet and install the crystal in a communications system. Now in order to try and change-up this story for volume two, the author had her do almost exactly the same thing. Instead of black crystal, which had somehow been tragically lost in a planetary storm, she was mining white crystal - and sure enough he had to go off planet to install it in a system. Same old, same old....
This losing of her invaluable black crystal open-face 'mine' made zero sense. Yes, even give that a violent wind storm could wreck her mine face - which is a stretch - this crystal was so valuable and useful that it was unthinkable there would not have been a major effort to uncover that vein again, so premise was fouled right there. But having her repeat the first story - mine the crystal, escort it to another planet and install it? Boring.
The author tried to change this up by having a ridiculously conformist society whereas Killashandra is a bit of a rebel of course, and have an assassination plot. Yes, Killashandra was hit by what had evidently been an intended three-pronged bolt of death come at her, which she escaped with only minor injury.
Later when she snuck off without her escort, she was kidnapped and abandoned on a remote island. Why did this assailant try to kill her and then when he had her in his clutches, simply abandon her on an island instead of killing her as he had originally intended? It made no sense. But it got worse. She managed to escape from this and get back to society, but coincidence of coincidences, she ran right into the very same man who had tried to kill her and then had abducted her. He didn't recognize her - the most famous woman on his planet - because she now had a suntan. What? But it got worse. She got the hots for him - for her attempted killer and kidnapper. I'm sorry but no! Fuck no! This story sucked and I'm done with this author.
