I picked this up because I enjoyed 56 Days, also by Catherine Ryan Howard. Solid serial killer victim out to catch the bad guy thriller. Some of the twists used were a little bit common, but it was done well. It kept me engaged through to the end. I especially liked the book within the book, a tell all by the MC who lost her family to the Nothing Man at 12 years old. 

This thriller won’t rock your world, but it’s not a bad read. I think it’s a great audiobook with two narrators for the different perspectives and the accents are a delight to listen to.
