Alpha Affinity

by Siberia Johnson

There’s no avoiding fate. I’m caught between the creature watching from the shadows and my rugged housemate with a dark side. Even if he turns out to be more beast than man, I can’t resist his bite.

Moving to an isolated town on the coast was supposed to be my fresh start. Instead, I crash my car in the fog and end up rescued by a man whose touch heats me from the inside out. The longer I deny it, the hotter I get, and the harder it is to keep our distance. They say becoming an alpha’s mate is too much for a human to handle, but he might just be the dominant I’ve been waiting for.

This was a great read and I really, really enjoyed it! It’s short but powerful. If you're a fan of paranormal romance with a broody alpha heros then this is definitely one to pick up.
The story follows Nova who moves across the country to a tiny and remote town for a fresh start. I loved her character. She’s smart and kind but also a little self conscious. (I love a relatable character!)
Out MMC is Roen, is big, scruffy, protective and bit of a mysterious guy. He's older and has that dominant "mountain man" vibe that is just so addictive.
The chemistry between them is instant and intense. You can feel the "fated mates" pull right from the beginning. This is definitely a spicy read! It's all about their powerful connection and how they navigate this new bond. I loved watching him be so protective and her growing as a person.
The author did a great job with the setting and world building too. The describes world brings a cozy and mysterious feel of the story which made me want to cozy up with a coffee and keep reading!
Overall this was a fantastic, steamy and satisfying paranormal romance. It’s a quick read and I want more. If you like protective alpha heroes, fated mates, and plenty of spice, I highly recommend it!

I do love a Wolf shifter so I was very keen to read this one. I’ve always liked Siberia’s writing style. Her books pull you in with world building that immerses you in the story, then the plot & spice hook you in for the full ride!

This was a captivating, short read with all the ingredients a spicy paranormal book needs! A somewhat reluctant Alpha & the new pack dentist he is inexplicably drawn to… she also happens to be human & knows nothing of his wolfy world. The spice was very nice & I really enjoyed how Nova & Roen’s relationship gradually developed. I’d love to see more of the characters featured throughout the book. Here’s hoping there more to come 🤞. Definitely recommend!!

I really enjoyed Alpha’s Affinity — it was such a captivating and spicy paranormal read! The world-building pulled me in right away with its mix of shifters, fated mates, and intense emotional bonds. The chemistry between the characters was undeniable, and the tension built perfectly from the very first encounter.

The writing was smooth and engaging, and the dynamic between the leads had just the right balance of dominance, passion, and heart. The author did a great job showing the raw, primal connection between the characters while still giving moments of tenderness and emotional depth. The spice definitely delivered — 🌶️🌶️🌶️🌶️/5 — hot, detailed, and tied beautifully to the story rather than just thrown in for heat.

My only complaint? I wish it had been longer! The pacing was quick, and I found myself wanting more time in this world — more backstory, more scenes between the characters, and a little more exploration of the secondary cast. It felt like it ended too soon, which only shows how invested I was.

Overall, Alpha’s Affinity was a steamy, fast-paced, and satisfying paranormal romance that left me wanting more (in the best way). If you love fated mates, shifter heat, and a touch of darkness, this one is definitely worth reading — I just hope the author gives us an extended edition or sequel soon!

This was such a great spicy and quick read. I devoured it, just like the first time she let me read it. I loved so much about this novella, from the moody woods and beach to the quaint little town it takes place in.

I’m a sucker for a shifter romance and this was the perfect moody fall spicy read. I love how these two finally come together and how insane their chemistry is in such a short time. I won’t spoil anything ,but you should add this to your to your fall TBR.

📖Book Review📖

Alpha Affinity

I really enjoyed this book, it was short and fast paced and OMG it was so so hot 🥵. I was hooked on the story from the start and didn’t want to put it down, I’m hoping Siberia will continue this series as I personally found it very good and would very much like to see more. Especially Olivia’s story.

I do love a good shifter romance with fated mates & that’s spicy. Perfect for spooky season.

The only thing I would say is I think the story could use just a little more work (like just a smidge) because there was some little bits to me that didn’t make sense (only really minor stuff nothing big) but other then that it was really great and I would definitely recommend you read this book.

I also just figured out that there is another novella before this and you wanna bet I’m running to go get that right now. 💳💳💳

This book is a spicy alpha wolf novella. It follows Nova and Roen. Nova is a human starting over in a new town but on her way she gets into a car accident. Roen is on his way home when he comes across a car accident. Soon things starts to heat up between them. How long can they stay apart before the inevitable happens.

I love Siberia’s writing. Her books are always captivating and amazing reads. This one was no different.

It was a quick 97p read with just enough spice and a decent story line. I would love to read more of the story and meet the rest of the pack as the book only follows the alpha. It is a fast pace story and Nora is relatable. Roen with alpha any Luna needs

Thank you Siberia Johnson for sending me this book in exchange for my honest review.

Just finished this short story/ novella written by Siberia Johnson.
Very fast paced. There is an event that happens at the end of the first chapter that really
hooks you into the story.
I found Nova to be somewhat relatable. I also love the
mention of Nova's smutty audio book.
I really enjoyed the world the author created and I devoured the book so fast!
There is a good amount of spice, so if you like spice you will enjoy this book!
This is my first book by Siberia Johnson, and it won't be my last!
Alpha Infinity is available for pre- order on KU. and releases October 23rd.

Human in heat
This is a short smutty shifter romance. Nova is a human starting over in a new town but on her way she gets into a car accident. Roen is on his way home when he comes across a car accident. Nova start to go into heat (which shouldn't be possible for a human) and Roen helps his mate through it. There wasn't really much to it. It was quick and smutty and a book that I read.

This was a spicy hot short wolf shifter story was entertaining to read. This story is about Nova a new dental specialist and Roen our alpha wolf shifter. Nova is driving across country to her new dental job on a rainy night when she has a car accident. She's rescued by Roen who's driving home. Roen drives her to her assigned apartment. What occurs as Nova dreams about a wolf and afterwards was a well written romance story with steam and likable characters. I'd volunteer to read and review this copy I'd received.

[Megan Green · Rating 5 out of 5]

I’m conflicted. I love Siberias writing style and I love novellas but Siberias ability to world build means a novella leaves me wanting more (in the best way)

I’m super picky about shifter romances but I’m feral (see what I did there?) for a protective alpha age gap, and Siberia definitely delivers. You could feel the fated mate chemistry jump off the page from the MCs first meeting and I was instantly hooked.

4.7/5 ⭐️

This is going on my re-read list for sure.

need a quick, spicy, wolf shifter book. well here's you one.
super fast paced, obviously since it's only 95 pages.
I could have definitely read a full story with these characters.

thank you Siberia for the arc. 🫶🏻🫶🏻

[Jennifer Ervine · Rating 5 out of 5]

I’m always left wanting more with Siberia’s Monster’s Mate books! So much emotion and spice for a small novella. I love a good fated mates story and Roen and Nova are so swoon-worthy. I can’t wait for the next!
