I really liked the concept and design. very creative. love how each chapter was a different ORSK item. But the writing lacked substance. there were so many opportunities where tension could be drawn out or moments that could've been much scarier. amy was not a good protagonist, she was annoying and bratty, absolutely did not care about her. however, the side characters had more personality and added comedic elements to the story. 
i also enjoyed the elements of the cycles of work/labor but it needed to be more drawn out for it to be a bigger element. 
i wish grady could rewrite the book with the horror-chops he has now.
