The premise is fascinating. In a universe where many alien cultures are interacting with each other whose morals, and whose justice system prevails? Rusch's answer is that justice is relative, and her protagonist Miles Flint struggles hard with the morality of that.
Flint is obscenely super-wealthy. That's unusual in a detective story. Everything else about him, though, follows detective-story expectations: he's an ex-cop; he's got a prickly relationship with a cop in high places upon which a plot point will turn; he's a computer genius and hacks something unhackable regularly; he has a Tragic Back Story and is Damaged (but not irreparably). I sound sarcastic and I'm not: I have a real love of Rusch's writing. The books are fun, the plots are internally consistent and satisfying things happen at the end. Also - aliens!
Kovacs huddled against the edge of the crevasse. Below him, the massive rip in the glacier extended several hundred meters, narrowing as it deepened. He had no idea how deep the crevasse was, but he knew that a fall would kill him.Last line:
Unquotable. Despite the aliens these are private eye stories. The last line is always a spoiler.
