Third in a trilogy, the Themis story is as gripping in this last novel as it was in the first two, the characters as real as any you've met personally. The story wraps up the trilogy with the end of the robot story. The why, who and where of it are answered and addressed. It's a particularly emotional book in that the main characters finally duke it out over their deep disagreements and yes, work something out. I'm hoping Sylvain does another series as his science fiction writing is entrancing and gripping and exciting. All the reasons for reading a good book.
