The setting of the book is based in the future sixty years from the publishing of this book. Most of the characters work in the detective bureau in Boston PD, with other characters outside of the division sprinkled in to provide the variety of life necessary to keep things interesting as needed. Given the storyline is in the future, naturally there are going to be elements of possible future tech involved in the equation.
A good mystery, whodunit, detective novel with glimmers of science fiction wrapped around by a causational flow of energy to help keep the story moving from start to finish sprinkled with a touch of a love story while being enhanced through metaphysics.
With that being said, the involved cast of characters do what they can to solve the ongoing developments of the case(s) as they continue to deal with their own personal struggles, some of which are unexpected. This was done to keep things in perspective with the hope that the characters would appear more multidimensional than flat, like the words streaming across the page in lackluster fashion.
