Reya is a Redeemer.  She is the last person someone sees before they die.  She is their last chance at salvation.  Sort of a soul-cleansing grim reaper if you will. 

Thane is a dirty cop whose soul is on the verge of becoming lost.  He, along with his partner, head up the paranormal investigation unit in the police force.  His path crosses with Reya as he is called in to investigate the "accidental" deaths of so many citizens. 

At first the book was somewhat confusing.  The various dimensions and ascending worlds sent me threw a loop a few times.  However, I liked the over concept and the book was well-written.  The characters developed and grew throughout the story.  Over all I give the book three stars.
