I finished the 473 pages in about 4 days. It has very much the same feel of the first book. If you enjoyed the previous book, you will enjoy this one.
This is a hard science fiction book with multiple viewpoints from the different characters. We even see internal dialog from two alien intelligences.
The story is a continuation of what transpired in the first book. The Earth has been stolen and transported to a nursery of worlds controlled by an alien intellect that does not even recognize the existence of human beings. Humans on Earth and the abandoned Solar System attempt to restore contact between the two branches of humanity.
All the same characters are involved as were introduced in the first book. Two new scientists are introduced on the Stolen Earth who play important roles and the Autocrat of Ceres is shown with his ship that will be important.
The reason some people would not like this book is because of the constant information dumps. This story is about gravity beam, tunnels, radios and other gravity based technologies. The plot is dependent upon the operation of black holes, neutron stars, fusion engines and radar devices. The narration and dialog constantly refers to the needed facts and theories on which the plot twists rely.
I enjoyed the heavy hard science mumbo-jumbo in the book, but I suspect many readers would not tolerate it. This book is for hard science fans who are interested in conflict with alien intelligences. ( )

To this day I cannot wait for the next book in this series. Just like the first installment in the Hunted Earth series, The Shattered Sphere was excellent. This book picks up where its predecessor left off. Earth has been stolen by robotic aliens that were awakened by humanities own experiments into gravity manipulation. In this book Earth begins to explore the new multisystem it finds itself in and the rest of humanity that was left behind in the solar system searches for a way to get Earth back where it belongs. The Shattered Sphere is an excellent follow up to The Ring of Charon, the only let down is that after a decade and a half there has been no follow up to this wonderful and intriguing storyline. ( )
