I will be doing a full review for this book soon on my booktube channel, but for now I will say 3 things:

1. Do not go into this book expecting the profound story of Les Miserables. It's very watered down and only really shows the second half of the story, focusing around the characters based off of Marius, Cosette, and Eponine. And Javert's beef with Jean Valjean is basically nonexistent except for two sentences.
Ok I don't want this to turn into a rant so I'm moving on.

2. The characters are not well developed (except maybe Chatine) and they are all very annoying.

3. The worldbuilding was excellent! Nice job.
