I'm kinda leaning towards 4 stars, but I'll be nice and give it 4.5 ONLY BECAUSE THE PLOT WAS THE MOST WELL-THOUGHT OUT CON (heist?) I'VE EVER READ! 
 I rejoice seeing the ol' gang together, but sometimes the pace and overly flowery-personified writing slowed me down. I'll be honest: it was not a quick book (neither short in length). I lovedddd that we got to know more about the characters, and they were much more finer details than Six of Crows which felt like a biography sometimes. 
 People loved it so much, and I feel this awkward stage of liking it and disliking it. Nonetheless, the story was beautiful and really emotional, the characters have this sense of absolute depth that YA heroines and hero's seem to lack. I stopped near the end, and this may or may not be my stupid habit of reading the last pages of a book before starting it............. 
 Give this series a try because it's definitely worth it, but not everyone will come out absolutely loving it.
