Asimov completed this book much later than the first two in the series. Knowing this, and curious to see if his writing style had changed, I would say that it is more descriptive (the book is indeed much longer) but altogether stays very much true to the voice of the other works.
This book is a triumphant tale for earthmen, the general progress of humanity, and productive compromise. The murder mystery itself causes much consternation to both Elijah Baley and the reader, but it comes with many discoveries about the case that prevent throwing down the book in disgust. Baley again delves into a foreign culture, this time with less encouragement and much more pressure, and finds that the Aurorans are not as perfect as they think suppose to be.It starts on earth where Baley has succeeded in putting together a group to begin to acclimate themselves to the outdoors and learn to live on a natural planet without the crutch of the City. This is all well and good but the Spacers control all space travel and their allowance is needed for any new colonization to occur. On Aurora this is the core of the fierce political battle dividing the legislature. Spacers have become stagnant and isolated whereas earthmen have become coddled and dependent on the hive. The Globalist party wants to see Aurorans and only Aurorans colonizing new worlds, but this will not be possible for them unless they use humaniform robots. But the only scientist who has created them and could possibly know how to do so sees the folly in the Globalists’ plans and will not surrender his knowledge. Lije Baley manages to solve the case only by navigating the political battle as well.
The new variable in this book is the robot Giskard (who has a big fan in Kate Barber =D ), a robot much more interesting and involved in the case than he may seem. Asimov continues to use Baley to address important questions such as robot-human relations, humans’ romantic and familial relationships, and the Three Laws of Robotics. In all three books, watch out for the statements in parentheses, there are some sucker-punch statements hidden in there.
