It was great to see Jude and Cardan and their court again, and to spend some more time with Oak in their company. And to see how they've changed and haven't changed, and how their protecting Oak has also messed him up in a way. 
But I was a bit disappointed in Wren's storyline. She's barely in this book. At the end of the last book I had been excited to see her claim her power and exert her own agency. That's already mostly gone again by the time this book starts. I wish we'd seen more of her POV, and I wish she had had the chance to be more active in her own story.
