I need this in a full length novel, I beg of you!!

• Primal chase
• Kidnapping
• BIPOC FMC
• Blood/Gore
• Monster sex
• Insta-obsessed MMC
• non-human MMC

This novella was the perfect hot, spicy, monster story I didn’t know I needed!

Under 50 pages, I read this so fast I kept hoping there was more and more!

I loved the writing, and would love to read more from the other now- and next Christmas, make this full length 😭🙏🏼

Holy F*ck. I loved this.

41 pages of smut that was absolutely delectable. Krampus sounds hot, and this had death and pain with some good spice and a little plot that was super enjoyable. I would definitely read a longer gorier version of this, and I highly recommend it for anyone wanting a Christmas novella that is dark.

There were a shit-ton of em dashes, which could be a sign of ai. I personally use them, but this was A LOT so idk. Fair warning.

Thanks R&R book tours for sending me an e-ARC today for sharing a post on this tomorrow :)

Yule Sin is an erotic horror holiday novella that packs a punch despite its brevity. Featuring Krampus as a central figure, this tale unveils his obsession with Selena, while also offering varied perspectives on characters like Tom and Kimberly.
Prepare for the perfect mix of festive cheer, dark suspense, and steamy chaos. If you're looking to experience Christmas from a fresh angle this year, this book should definitely be on your TBR list. It embraces a delightful kind of messiness that adds to the fun. Everyone should give this a read; it will change your view of Christmas in the most wonderful way. Just remember to check the trigger warnings!

A short, twisted holiday novella that fully commits to erotic horror. Snowed in, power out, and Krampus on the loose, this story is dark, fast-paced, and unapologetically unhinged. The multiple POVs keep things tense, the killer gingerbread men are wild in the best way, and the ending twist was a nice touch that leaves you thinking. Messy, creepy, festive, and fun if you like your Christmas reads on the darker side.

“Krampus had truly come to town.”

This maybe festive themed but it aint no fairytale thats for sure! Selena wasnt looking forward to Christmas with her inlaws coming, and discovering her husband affair but thats gonna be the least of her worries when Krampus comes to town. Well written steamy short quick horror erotica, and the ending is for you to decide!

Yule Sin is an erotic horror holiday novella. A nice little quick read for Krampusnacht. There's not much to say about it, it's a super binge-able novella. There's multiple points of view, but the main two come from our BIPOC fmc, Selena and our mmc, Krampus himself. It was a dark, fun (in a twisted way) read. I don't think I will ever look at Krampus the same way again. 😆

This is the first book by this author that’s out and I’m glad I picked it up. There’s different perspectives of Selena, Krampus, Tom, and Kimberly that take place within.

If you want a short and spicy book that focuses on Krampus and the things he does to others then you should check this one out.

Eeekkkk this story was short spicyyy and to the point y'all.... And it really makes you think about all those old wives tales, old bedtime stories, old folklore, and all those old urban legends we hear as kids... I mean those stories had to come from somewhere right and some sort of truth behind them riiiiggghhtt???

Do you believe in Krumpus? What would you do if you find him in your bed? This is a quick actioned packed novella with some kidnapping, primal chase, obsessed non human mmc and some monster adult fun. For me it’s a HEA, everyone got exactly what they deserved for Christmas.

Oh so spicy Krampus horror erotica 😈

Loved the primal chase trope, and how he was instantly OBSESSED with Selena.
The ending fucking threw me! No lie my jaw dropped.

Very quick & fun horror erotica read.

A perfect hot, spicy Christmas novella. It was under 50 pages and it was something I didn’t know I needed to read! A great dark holiday read about Mr. Krampus and I would love to read a full length novel of this!!!!

A short holiday murder

The authors says this isn't a happy ending, but I'm not sure what else to call it. This short story has krampus being some people's nightmare and others, their "happy ending". ;)

The length of the story was perfect and there wasn't any unnecessary fluff.

Holiday horror has never tasted so good 🔥 The perfect blend of festive vibes, dark thrills, and steamy chaos. Krampus was an absolute menace in the best way. Bring on the rest of the series!
