I have lots of anger - too much to write a comprehensible review so I'll just bullet list things.

I'll start with the positives:
-it had art therapy and therapy for children. good.
-it was short

Whew. Now for some rage-inducing moments:
-Feyre is literally

suffering from PTSD and is then guilted into the idea of having children by a woman who was married for 300 years (important) but regretted not having a child with her deceased husband. Feyre then has anxiety thoughts about her trauma, Rhys' death, happening... again... and comes to the conclusion that they must have a baby despite stating in other books that she wants to experience life and marriage and happiness before bringing a child into the world (very admirable). And yet after a like, 7 month relationship she changes her mind because WHAT IF anxieties.

Fuck that noise.
- Feyre is an absolute menace to everyone around her. The only exception being Rhysand because he's ~perfect~. She not only can't mind her own fucking business about Nesta, whom she couldn't even bother to buy an actual gift for on the holiday even though she spends like 50% of the book trying to bully Nesta into being a big, happy family~ (giving her rent money does not fucking count), but also has to try and convince Elain that she should give Lucien 'a chance' because he's 'a good male'. AND THEN to tell Lucien that he shouldn't have friends, a.k.a The Exiles, because he should live with them, where he's not particularly wanted by anyone, least of all Elain, because isn't she his friend??? AND THEN TO GET MAD AT HIM FOR REJECTING HER OFFER BECAUSE DOESN'T HE OWE HER? But then in the same breath think that she will never apologize for all the wrong she has done to him. Fuck her. Feyre is basically just a femcel but with collecting people under the same roof.
-Feyre's constant narrative of "this is so expensive. I am so rich now but I hate spending money. I could spend so much money but I won't because ~I have morals~". Go drown.
-Mor still exists.
-"Gentlemales."
