I have only recently become a fan of the Lux series.
This is a VERY short story. Daemon and Katy get married (and it's, like, less than 10 pages).
I did enjoy the book, but the only reason I'm rating it 3 stars instead of 4 or 5 is because it was too short in my opinion. It would have been better if it was longer. Although, it was nice to see the characters.
