Numbers in ACOTAR
This is the first time I'm sharing a theory of mine... I had posted this before on tiktok and Instagram (November 24th, 2023) I am reposting it bc I wasn't satisfied with the layout and it wasn't as detailed as this one. Oh and also English isn't my first language so pls don't mind if theres anything wrong in the grammar or if im bad at explaining xx
There will be SPOILERS for the entirety of ACOTAR series and House of Sky and Breath aka HOSAB!
SJM is known for using numbers like 3, 7, & 13 as symbolic constants in her worldbuilding. Theyâre familiar, but theyâre also intentional. She uses these numbers like most fantasy authors.
However, there are some additional numbers that she has used, which are unusual of her to use and that make them stand out. Letâs take a look at these numbers:
21 & 5
In ACOSF chapter 56 (I will get back to this number later on) Gwyn gifts both Nesta & Emerie a book at Solstice. She tells them both to look at chapter 21 and page 5 (will come back to this number too).
She then tells us that this chapter is about the Valkyries death & Rebirth (aka herself, Nesta and Emerie).
âAt the top of the first page, it merely said, Chapter Twenty-One.â
Notice how Twenty-One is written in cursive? Coincidence? I think not. SJM wanted us to notice this.
I noticed the unusual use of number 21 & 5. This was the first time SJM had used these numbers, so I did as Gwyn said. I checked chapter 21 and page 5 of each ACOTAR books to see what the key points of each chapter and page were. Then I also did some research on the number (21) itself as well.
Symbolism of 21
The number 21 in literature isnât just a number. The number has been found in various works like art, mythology and literature. The number has been used to serve as a symbol of âcompletion, transition, or personal growth.â  More so the number has also been used to portray âcharactersâ coming-of-age, spiritual evolution, or a turning point in the narrative.â
As we hear from Gwyn, she made Merill add the Valkyries in a book, in chapter 21. We see that there is a turning point in the narrative with the Rebirth of the Valkyries.
The number is also used in the Bible. It is associated with resurrection. Death and Rebirth.
Now letâs ask ourselves this: Which two characters are associated with Death & Rebirth in ACOTAR?
Answer: Azriel & Elain
âI saw the painting in my mind: the lovely fawn, blooming spring vibrant behind her. Standing before Death, shadows and terrors lurking over his shoulder. Light and dark, the space between their bodies a blend of the two. The only bridge of connection ⊠that knife.â - A Court of Wings and Ruin
(Fawn symbolizes Rebirth)
CHAPTER 21
ACOSF
In ACOSF chapter 21 we see Nesta having a conversation with Elain. The conversation is about wether or not Elain should be scrying for the Dread Troves.
Elain wants to do it, but Nesta doesnât want Elain to do it. With this they have an argument and Nesta says:
âLook at who decided to grow claws after all (...) Maybe youâll become interesting at last, Elain.â
âFind me when you wish to begin.â
We see that Elain doesnât want to just sit and be quiet anymore, she wants to do more, be more involved with helping. There is a turning point in the narrative here and perhaps even a hint at who the next book is about
Letâs also not forget the Feysand bonus chapter is right after chapter 21 so it could count as 21.5 & Feysand talked about Elain: âLetâs focus on helping one sister before we start on the other.â A hint to say  we will first read about Nesta, then Elain.
âI think sheâs kind, and Iâll take kindness over nastiness any day. But I also think we havenât yet seen all she has to offer (âŠ) Donât forget that gardening often results in something pretty, but it involves getting oneâs hand dirty along the way.â âAnd thorn up by thornsâ - Feysand Bonus
Feysand are talking about how there is more to Elain than we know.
ACOTAR
In ACOTAR chapter 21 we see Feyre at Calanmai.
âEverything about the stranger radiated sensual grace and ease. High Fae, no doubt. His short black hair gleamed like a ravenâs feathers, offsetting his pale skin and blue eyes so deep they were violet, even in the firelight. They twinkled with amusement as he beheld me.â
This is the moment Feyre meets Rhys. This is the moment where we the readers get introduced to him as well. With Feyre meeting Rhys, there becomes a turning point in the story and as readers we knew Rhysand was going to have a bigger impact on Feyreâs story.
ACOMAF
In ACOMAF chapter 21 we see Feyre at the Weaverâs cottage.
âI froze, the ring now in my pocket of my jacket.â
Feyre gets the ring Rhysandâs mother had given to the Weaver. Rhysâs mother had said only his bride would be able to retrieve it from the Weaver (Which Feyre ofc did) and this ring ends up being Feyreâs engagement ring. Rhys had told Feyre about the ring after she had retrieved it. When they got engaged this ring was important (Itâs even on the cover of ACOMAF). Feyre become the first High Lady wearing this ring. A turning point in the narrative; High Lady of Night Court.
ACOWAR
In ACOMAF chapter 21 we see Nesta is starting to train her powers (after being Made) with Amren. Not only that, but we also find out that Feyre is going to the Prison.
âTo find my sister and Amren. To see which of them was still standing after their first lessonâ âThe fewer people who knew about my trip tomorrow to see the Carver, the safer it wasâ
Nesta training with Amren becomes important for Nestaâs character arc in ACOWAR, but it also becomes important for ACOSF. It also can be seen as a hint given by SJM about Nesta potentially getting her own book (Which she eventually got and again her training her powers were important.
And with Feyre going to the Prison, we get a climpse of Feyreâs future. The Bone Carver shows himself as her son to Feyre.
ACOFAS
In ACOFAS chapter 21 we get into Cassianâs POV for the first time (If we donât count Wings and Embers). We see that there is something going on between Cassian and Nesta (hinting on the next book is theirs as SJM said; She put breadcrumbs in ACOFAS for the upcoming spin-off books in this book)
âHe remained staring after her, that present in his hands. Cassianâs fingertips dug into the soft wood of the small box. He was grateful the streets were empty when he hurled that box into the Sidra.â
Cassian throws away the gift he had gotten for Nesta as she rejects it. This gift was important enough for Cassian to give to Nesta, but when she rejects it, he gets rid of it (seems familiar to another moment right?) The gift gets brought up once again in ACOSF.
(Added: Oh, I just remembered this; letâs not forget Feyreâs birthday is on the 21st of December! And she is 21 when she gives birth to Nyx! Again, Feyreâs birthday was a turning point in the world itself, if Feyre hadnât been born that day, Prythian could still have been under Amaranthaâs rule. with Nyxâs birth, we get a turning point in Feyreâs story, sheâs having her own family with her husband/mate and the kid is the heir of Night Court â> Next High Lord)
PAGE 5
Cassian throws away the gift he had gotten for Nesta as she rejects it. This gift was important enough for Cassian to give to Nesta, but when she rejects it, he gets rid of it (seems familiar to another moment right?) The gift gets brought up once again in ACOSF.
ACOTAR & ACOMAF
In ACOTAR, page 5 is where Feyre shoots the wolf (Andras) with her ash arrow. This becomes the beginning of the turning point in Feyreâs story. She shoots a Fae, which leads to her ending up in the Spring Court.
In ACOMAF, page 5 we see Feyre struggling and dealing after everything she had endured Under The Mountain. This also becomes a turning point in Feyreâs story, itâs important for us readers to see, to understand and feel with her. We see that she isnât doing well mentally.
ACOWAR & ACOFAS & ACOSF
In ACOWAR, there isnât any pages with the number 5 and that is because Part 1 of the book is there. The Part is called âPrincess of Carrionâ which is a title given to Feyre.
In ACOFAS, page 5 the twins Naula & Cerridwen getâs mentioned several times. (Who are they friends with? Elain. And who do they get trained by and work for? Azriel.)
And last but not least, ACOSF, page 5 does not exist once again. The fifth page is Part 1 of the book and the Part is called: âNoviceâ
Novice means:Â a person who has just started learning or doing something.
This is an indication to Nestaâs journey, her being a Novice in the beginning of her book.
NUMBER 56
(HOSAB SPOILER!)
Now letâs get back to this number before we conclude this whole theory.
Did SJM also give us a hint from HOSAB?
In HOSAB there is someone called BansheeFan56. Now look at the username/address once again... Number 56!
Again, this isnât a number SJM typically uses and for some reason this number stood out and then I noticed something...
In what chapter did Gwyn give the Solstice gift of Chapter 21 to Nesta & Emerie? (and basically us)
Answer: Chapter 56.
I guess SJM do love to use numbers as a hinting tool
CONCLUSION
Now with everything we know about Chapter 21 & page 5, we can come to the conclusion of who the next book is going to be focusing on.
In ACOSF chapter 21, Nesta notices that Elain is growing. In the bonus chapter 21.5, Feysand talks about how they will focus on helping Elain, after helping Nesta. Nestaâs self healing journey has been written, but her journey may not be over yet. I do think we will see more of her, but I donât think there will be huge focus on her again like in ACOSF.
Itâs time for us to focus on Elain now and there is a lot to discover about Elain.
SJM did say each book in the spin off will focus on a couple and Nessian has had their book now, so Iâm certain that Nesta wonât get another book or trilogy.
Numbers has become a pattern in the ACOTAR series.
3 brothers, 3 sisters, 3 stars, 3 peaks, 3 mountains, 7 courts, 7 High Lords etc, but now we can also add 21 & 5 into this.
Chapter 21 gives us a hint for something important that is happening or going to happen
page 5 shows us some turning points as well.
The 21st chapter becomes key to the book and the upcoming one. And the 21st chapter of ACOSF hints for the upcoming book to be Elain's and most likely have Azriel as the love interest since he got a bonus chapter in ACOSF, like Cassian got a bonus chapter in ACOMAF.
Plus both Bonus chapters are focused on Elain as well.
With all that said, I want to say thank you to my friends who has helped and supported me with this theory. And also thank you (reader) for taking your time to read about my theory about SJMâs use of numbers. I hope it makes sense for you guys as it does for me and I hope you enjoyed reading this <33
I also like to thank our Gwynie for giving us the hint that the next book is focusing on Elain <3
I'm rooting for a diverse book, but I would sacrifice 10 virgin men for 1 book about Tamlin's entire trajectory, his relationship with his father, the beginning of Amarantha's obsession, which began since childhood (was there any other reason for this?), the friendship with Rhysand until the tragedy with the families (was Tamlin really indirectly responsible for the death of Rhysand's mother and sister? Did they really die?);
Why is there a lake of starlight in his court and why does he love it so much there?
What happened to Tamlin in Under the Mountain? Why is he so reclusive and evasive about his own story?
Will he connect to Koschei's plot? So many questions.
I almost forgot, his friendship with Lucien! Or with Eris. I need details on how Lucien ended up in Tamlin's arms.
Iâm going the pretend that I donât care about ACOTAR anymore so we could get an announcement.
Dude?!
Sounds like sheâll hop around if itâs 4 parts over 3 books!!!!
So will we get Az & Gwynâs story at the same time we get Lucien & Elain, as well as Mor & Emerie?
I cannot hardly wait. Mother, I hope part 4 isnât a long ass wait
Edit: once I thought about all the plots she needs to wrap up. It would a lot for one book. Even if itâs 4 parts and 3 bindings. See my other post

âBut he could have this. This one moment, and maybe a taste, and that would be it.â
And then getting interrupted and never finishing the moment is perfect setup for their book
Me coming out of my retirement to check out the state of the fandom:
I'm gonna say something
Don't you guys think Fanon Azriel is too soft and cuddly? Like every fanfiction, theories we have of him is something cute and a bit nerdy?
Well as the canon Az could be way, way, way darker? More unhinged? Scarier, colder. We had him suffocate Eris to near death without a sound coming out of his mouth. We had Rhys apologizing to Feyre for her to witness 10 minutes of Azriel doing his fucking job.
I truly think he's mentally un-okay. Don't get me wrong, I LOVE it.
