Third book of the Margin Street Zeroes book series, and my personal favorite.
The gods have sent them someone, AK, to help Gio and Frankie get used to ther new situation. Mostly, they are just continuing their lives as always. A new school year starts, they have to prepare for winter and that it will be cold, the three raccoons are back, and some other things that come up. Really it is just the continuation of the story as we know from the first two books, mostly Real Life with the occasional magic. Some of it is fun, some is cute, some is sad.
As far as the writing is concerned, I feel that Banks is getting better and better with time, but it may be just an impression. I did enjoy the way they altered between the fun/cute and the serious/sad in this book, it sometimes happened really fast and it worked because Frankie's emotions are so intense, they keep dragging the reader with them because yes, we are coming from a funeral, but THERE ARE DOGHNUTS!!
As far as representation is concerned, there are of course still Gio and Frankie and their genderqueer and agender identities, but the book also introduces an ace (and possibly aro, none of the terms were used) character (AK) and another who has been there all along also comes out as ace (and possibly aro) (Ben (I KNEW IT WOULD BE BEN, I KNEW IT!!!)). Also, Frankie's VERY obvious ADHD is finally called by name and they got to deal a bit with what it means to discover that you are the way you are because of neurodivergence. So that was pretty cool. As always, I would have enjoyed to see a little more of Ben and AK, but that is more the “I wish there was fanfiction” kind, and not the “the book should have been different” kind of feeling.
