Another winner from Matthew Cox!  This is an interesting mixture of science fiction and ghosts.  The characters are real.  The situations keep you on the edge of your seat.  This is a remarkable series of crimes, peril, and the paranormal.  This isn’t a book you want to fly through, but rather, it is one to savor and enjoy.
Note: This book continues after book 1, so definitely book 1 first to truly enjoy this masterpiece.
