Knot Today Satan: A Halloween Novella

Rate this book
An angel-costumed Omega, an accidental summoning, and one lonely devil.

Art student Eden Evans is your average college-going omega. When she's not in class, she's either painting or waiting for her alpha crush to finally notice her.

That is, until the annual Kappa Sigma Psi Halloween party arrives to shake things up. It's the place to be on October 31st, and Eden's art skills just landed her a coveted invite.

Now all she needs to do is help decorate for the party. Easy-peasy, right? Wrong.

When Eden's decorating attempts summon a whole lot more than spooky vibes, her Halloween night quickly goes from fun to downright sinful. Read at your own risk...and Happy Halloween!

This is going to be an MF omegaverse tale that features a plus-sized FMC and, well, Satan. This is definitely going to be a walk on the wild side and will not be as fluffy as Calliope's prior OV series. Please read the list of triggers carefully before reading.

1st read: 4⭐️

i don't say this lightly, so listen up. if you love katee robert...read this.

i definitely had no idea what i was getting into with all the omega verse stuff...but this ABSOLUTELY could have been a full length novel. comfy college setting, healthy female friendships, and festive halloween vibes...all tied up in a well written bow! a little ashamed to admit i thought the title was a knitting pun or something at first...but i have since been enlightened. see? this is educational literature.

2nd Read: 4.5⭐️

decided to reread before continuing with the sequel, and it held UP to my expectations and very high regard for it from my first read. absolutely one of the best novellas i've read.

Amazing title for an Omegaverse with Satan as the MMC. But if you expect a bananapants, OTT, "what did I just read" wild ride (like I did), you might be disappointed. Expect the Mundane Fantastic trope on a college campus, with some fun OV smut. (Free on KU)

The plot: Eden is in college for her art degree. She has a crush on a jock. She goes to a party and walks in on him banging another girl. Her feeling are hurt but she's also turned on. She works on her art projects and occasionally has horny dreams about a mysterious mist. These vague dreams are sort-of shared by Luc (aka Lucifer), who's CEO of Hell.

Eden agrees to paint occult symbol decorations for a Halloween party that the fraternity is having. Her roommate gives her a sexy makeover and she goes to the party. While painting the symbols, she goes into heat and accidentally activates a spell that summons Satan.

Finally, 45% into the book, they meet. After a very brief conversation, they

Stuff I really liked: Luc was a pretty great MMC. The smut is good, including some praise kink, size kink, horn play, and pseudo-exhibitionism. At one point, Luc clones himself and they have a literal Devil's Threesome 😈👱‍♀️😈. (I so badly wanted to see a joke about it!)

Also, the author kindly includes content warnings in the beginning. The title, premise, and cover are awesome.

But: the pacing was just off for me. We see multiple scenes of the FMC painting. And multiple scenes where "CEO Satan" goes through paperwork or discusses Human Resources. That's cute, but this is a novella. If some of the redundancy had been cut, and a little more relationship had been added, this would be a rave.

Safety:

OP Drama:
Separations?
Push/Pull?
Sexual History:
HEA/HFN?

Hot as crap Halloween novella 🔥🔥

Eden is in charge of decorating for a Halloween party at her college. She didn’t realize her art would summon Satan. Or that he would absolutely ravish her.

Holy smut. 🥵🔥 I don’t really have any other words for this. Just damn!

Although I do wish the ending was different, this was a great read!

This was fun.

Eden (virgin, college student, plus sized omega) is asked by some frat guys to draw scary symbols around their frat house to make it spooky for the Halloween party. While drawing the symbols, she also goes into heat. Very inconvenient!! She doesn't have to worry about not being satisfied though because she just summoned Lucifer, and he's all too willing to help her out. They screw in every way possible and even bring an extra into the mix. Though this doesn't have a traditional HEA, it's definitely a HFN.

I thought it was fun smut. It didn't make my toes tingle, but it's still good. I didn't feel like had much omegaverse in it, other than she's says she's an omega and she wants to build a nest and Lucifer has a knot. Those are the only references to that world.

OMG I am still giggling. Cute, quick read, with enough spice to keep ya flipping pages, and enough interesting and unique things (neon green goo) to make it memorable. So glad I read this for Halloween! Omegaverse novella, fricking adorable.

You know exactly what to expect when you go into this. And it is all you want from this kind of book. It is perfect in the way you want a short, smutty, well-written read. The MMC is great, the fmc just is there, but I didn't mind. There is not a lot of time for really getting to know them, but that is fine. Excellent in the short, smutty reads.

3.75 stars!

Thoughts: This was a truly wonderful little novella. I know a LOT of the reviews talk about how they don't meet til like 45% into the book, well it's a novella and once they do it's nothing but sex. So if you're coming for plot or really good story, this might not be the story for you. I LOVED this, and will enjoy reading it again.
I won't lie, as an ex-Catholic the jokes made about religion were hilarious, had me cackling.
And the SMUT, OH MY GOODNESS was it delicious and so inventive. I never imagined a story where someone would hook up with Lucifer himself but my goodness was it great. I highly recommend this for some great halloween smut.

I think the title and cover is enough of a review. The spice was good but it wasn't too out of this world which kind of threw me.

Super spicy omegaverse novella that I didn’t know I needed for spooky szn. 5/5 def recommend for all your spicy spooky szn needs lol.

I really liked that there was a good spice variety worked into such a short story without feeling overwhelming. I think it worked so well because of the heat aspects — my favorite part of OV in general. I enjoyed the characters too, our not-so-innocent-omega was a breath of fresh air & I really liked the author’s take on Lucifer.

Horn play taken to a whole new level 🔥 🥵
Filthy minded omega artist and a sinfully dedicated demon to make all her dreams come true 🔥
The connection they forged despite the coupling was supposed to be a one off thing 🔥🔥🔥
(honestly wouldn’t mind a second novella or for this to be turned into a full length novel)


~ One note — if the author happens to see this; there’s a continuity error in the beginning! You say initially that she perfumes at 15 and is sent off to the Omega Center, but later when she introduces her friend, she says they were 13 at the center together. Obv not make or break for the story but just caught my eye.

Knot Today Satan by @calliopestewartauthor review

This is my first book by this author and I really loved it. I will definitely be reading more from her.

This book is about an omega named Eden who is an art see student. She is always painting and can find inspiration with the little things. She keeps having this dream of being in a misty field and a clawed hand is coming up out of the ground. She goes to a party with her best friend Cleo and one of the guys on the football team asks if she will help paint and decorate the house they got for their annual Halloween party.

Luc is Satan and he lives in hell and he keeps smelling this very strong smell of Granny Smith apples. The strong it gets he knows that soon he will be summoned but what he doesn't expect is the gorgeous Angel who summons him. He decides he is going to make a deal with her. He makes a deal that he wants to spend her heat with her.

The spicy scenes were very hot and I wanted them to keep coming. The one with the Doppelganger was so damn hot 🥵🥵 like yess please.

this book had a fun premise but left me wanting SO much more.

Eden's an art student with a crush on a jock, until she walks in on him getting busy with someone else. Hurt? Sure. Turned on? Apparently yes. She's also having these steamy dreams about a mysterious mist... which turns out to be none other than Luc (short for Lucifer, because of course lol).

She agrees to paint some occult symbols for a frat Halloween party, gets a glow-up from her roommate, and ends up accidentally summoning Satan himself when her... uh, heat kicks in? Finally, half way at the book they meet. And after like five seconds of conversation, they're off banging in a pocket dimension for who-knows-how-long.

When she returns, no time has passed but she's got a mark on her hand and the promise of another hookup during her next heat. And that's... it? Girl, where's the build-up? Where's the tension? Where's the STORY😭?!

"Knot today, Satan. Is abo.." Stop right there! The "k" in knot tells me I'm about to read a short story with a devilish shibari, BDSM sex summoning party, and I'm all in!

Oh. How. Wrong. I. Was... the audacity of my confidence 😤 girl!!! who did I think I was?

I just dived into an omegaverse, a subgenre I didn't think I would ever be interested in....wrong again!

This is now a public announcement to all my besties/girlies if anything happens to me. *DELETE MY SEARCH HISTORY* The rabbit hole I fell down while reading this book!! 😳😳😳 I don't think drowning my devices in holy water would be enough.

Anyway, back to my thoughts on the book... loved it.

Asking for a friend... Would chalk pens work 🤔 or is it just chalk?

Kısa ve eğlenceli bir novella. Bir Halloween partisi için yanlışlıkla Satan’ın kendisini çağıran Eden’i okuyoruz. Çok derinlik ya da karakter gelişimi ya da dünya oluşturma beklemedim. Novella olduğu için bu yönlerden eksik olmasını bekliyordum ki öyle de zaten. Yazılan kısmı da eğleneceğim kadar iyiydi ama harika değildi. Karakterleri sevdim 2. kitabı da varmış yine novella. Bu kitap çok ortada bitmişti o yüzden 2’yi de okurum diye düşünüyorum.

Knot today Satan was a quick Halloween Omegaverse with some steamy scenes.

Eden is an artsy curvy introverted badass, and she deserves to have a little fun! 😈

You’re in for a treat with lots of kinks, including tongue, tail, and horn play.

I found Eden's POV to be boring and cliche but Luc's POV was interesting. Short and sweet, I guess.

It was a little frustrating not having the MCs meet until page 50, at 50% through the novella.

2.5 stars.

It takes way too long for Eden+Luc to meet. Luc was a very PG rated Satan. And while the smut was good, it's more of a HFN situation. So, not bad but also didn't wow me.

Sweet and Spicy Novella

Did I pick this book up just for the title?
Yes. Yes I did.
I’m not the biggest fan of NA books, but I just had to know what was going to happen. It’s not often that monster smut can take me by surprise with creativity, but this one did!

Spice: 5/5

Triggers: brief mention of poor parent child relations
