My experience of reading this book would get it five stars. I loved the writing, the setting, the characters, and the magic. I loved the words and sentences so much that I couldn't read quickly -- I had to savor everything about how it's put together. It's both charming and clever, and all of the characters show a spunk and ingenuity that just delighted me and constantly surprised me. I wanted to read this aloud to everyone on the train! I really enjoyed reading it. I'm looking forward to the movie! 
 Here are my crappy reviews or, rather, reactions about the first two novellas, which I don't really recommend: 
 > In Time can be read here. 
 > Sparks Rise can be read here.
