Immature and silly are adjectives that come to my mind when I think about this book. So many twists that didn't have the effect I believe the author was going for, coupled with how little I cared about the characters made the plot unremarkable. The world building (for the non-Toronto world that I can't even remember the name of) basically didn't exist. I know it's a spin-off series and I would understand it better if I read the main series, but I still felt the book didn't carry itself at all in that area. 
 And just a couple things I didn't like personally but other people probably wouldn't care about: 
 There was no romance, not even a little bit of steamy action. Very PG in a boring way. 
 The writing is irritating. The book reads like it was written by a 16 year old who's trying to be snarky and relatable. 
 But these are just my opinions, clearly a lot of people liked the book.
