I just finished it and I really liked it. I loved the setting and how vibrant and stubborn the main character is.

I wasn’t able to completely predict the ending so that’s always my mark for whether the plot is good or not. If I can guess, it makes the read “boring” or “meh.”

I liked the characters and their development but I agree with OP about Catalina. I think she’s purposefully a static character so we can contrast her docile personality to Noemìs.
