This was a page turner, a thriller, and perfect for the plane trip to a wintery Europe. The author has done some really interesting world building here - an AI that can predict crime and anti-social behavior, a future society with a "social" rating used for jobs and housing, and a Hawaii that was hit devastated by a tornado and about to be hit by another. The politics in this novel is also interesting - an insular US government only concerned with the continental US, a Chinese government that stepped in to eventually take over, and Islanders who are caught in the middle. The author is one of these Islanders in real life, and I bet her take on this is accurate.

This book is more near-future thriller than full science fiction. Nagata has written that also, a far-future series, and I look forward to reading another of her books soon.
