I'm not sure how to rate this books lol this was a wild ride. To be fair - I asked for something unhinged.. so that is on me. Some of the scenes were awesome and made the story more fantastical - but some of the scenes had me repeating "what the fuck is happening" over and over. 
I really did appreciate the detail to the arts and thought it was really cool all the paintings mentions are real life paintings. And I enjoyed the ending. 

My bad guesses:

After hearing this plot was paranormal I immediately thought little red riding hood and he's the big bad wolf - that was so far off. Then I was convinced he was Rumpelstiltskin - which I think would have been cool. The actual ending I would not classify as paranormal... but I liked how it tied together with the grandson!
