It was a slow start but the character development of Daneel and Giskard was amazing!

Watching the two become more human in different ways was fascinating, with Giskard representing a robot with empathy and Daneel representing human logic and illogicals.

I was saddened that this book didn't feature Elijah Baley but his descendant D.G Baley was clearly a stand-in for him and acceptable.

I absolutely loved this book, it is flawed yes but enough to overlook them.

Seeing how the Solarian's Humaniform robots were able to overrule the First Law because their definition of Human was altered, was a devious revelation that blew my mind.

However, seeing Daneel essentially rewrite his own programming to invent a Zeroth law was jaw dropping and an incredible twist! And the fact it was Elijahs last words to him that caused such a path was beautiful, from that point on, those words planted a seed that would be watered by life experience of Daneel. Seeing Gladia's speech was the spark that lit the flame. It was amazing.
Daneel's Positronic brain had become so humanlike that it was able to form abstract thought and reach for that intangible definition of what Humanity is. This formed the basis for Zeroth Law.

However, the story ended on a cliffhanger and extremely quickly, with so many loose ends and things left unsaid. We have no idea what happened to Gladia, nor how Daneel will change. This feels unfinished, and I've been so consumed by this incredible world built by Asimov, that it's actually heartbreaking that I will never know what comes next, as the Author is dead.
