Robots and Empire

Asimov really brought it back with this one. Robots and Empire had the thoughtful, logic-puzzle complexities of I, Robot that I felt were somewhat missing from the Lije Baley books. I loved Daneel and Giskard as protagonists having to work around their robotic nature in order to save humanity. I liked the Foundation callbacks, I liked Amadiro's scheme, and I found the debate around the Zeroth Law very compelling. A great conclusion.
