After taking a couple of days to think about this novella, it's just not a story that's going to stick with me. This book follows more of Feyre and Rhysand doing what they do, and that's not the story I was interested in. I wanted to see more of the side characters and less of the main, but that's just not what happened. Personally, I didn't feel that a "bridge" between acowar and the novellas was needed because the issues that the other characters would face in the future were set up well enough in acowar for me to get what would be going on in the novellas. And that's kind of how I feel about this book, that I could have completely skipped it and would have been able to pick up what would be happening in the other novellas and they would still make sense.
I think it's safe to say though that this was just how I felt, if you enjoyed Feyre and Rhysand in the original trilogy and want to see them in an everyday setting then you could still enjoy this. But for me, Feyre and Rhysand's story ended in acowar and I am fully ready to move on to other characters.
