I enjoyed this book. The premise of the book is completely unique and it was written well so as to keep me reading on to find out what happens next. I liked the main characters, Francis Sullivan and Marni Mullins and the way each chapter had a different POV was great so you could see what each person was thinking. The author even included multiple chapters from the perspective of the killer which were really grim and gory but it was fun to see their side of things and trying to guess who they and the collector were. It had a bit of a weird ending and sometimes the drama was a bit too much and fight scenes were hard to follow but overall it was a decent book with a few twists to keep you guessing.
