Hot Creeps #3

Such A Filthy Girl

Rate this book
Some might call it obsession, but I knew it was love. And I'd prove it to her.

LEO

She's finally coming home. This time, I won't let her go. Estella walked out of my life years ago, and I couldn't follow her. I've bided my time, watching her, waiting for her. With our parents' tenth anniversary party approaching, she can't avoid coming home. Three days will be all I have to win her over. To rid her of her boyfriend and take his place.

ESTELLA

It's unavoidable. He's unavoidable.
I've spent years trying to stay away from the obsessed, possessive Leo. The minute our parents met, he claimed me as his and I'd been running ever since. Running, because what he wanted, we couldn't have. And admitting I wanted it too would break my mom's heart.
I've made a life for myself and there's no way I'm going to let him ruin it.

Such A Filthy Girl is a forbidden romance in the Hot Creeps series. The MMC may be unhinged, but he's hot!

Major mixed feelings on this one based on how Leo and Estella finally came together. BUT, I floved Leo’s next-level obsession with his starshine. And don’t get me wrong, I knew there was cheating going on which is why it has zero effect on my rating!!

The Hot Creeps series just keeps getting better.

I am always down for a good taboo read and this one was good.

In this story you meet Leo. His obsession was admirable but his current living situation rendered him.

There was a moment where I felt the anxiety to plunge and do what feels like the impossible.

Estelle and Leo story was a non stop page turner read.

from the title alone … you should’ve already added this to your tbr 😍

i had the wonderful opportunity to alc listen to this book !! thank you so much effie 🖤 i love this series so damn much. and to relive it while listening to these characters and their story come to life was just amazing 😫

this is a taboo dark romance, forbidden, step siblings, cheating, stolen touches, filthy smut, duo pov, standalone novella 🖤

one night, estella and leo never would’ve thought one little kiss would lead to their demise. they haven’t seen each other in years since she left. but leo’s obsession and love for her never wavered. no matter how hard he tried to get over her, he never would forget the freckles that scattered across her face. estella had fallen in love or what she thought she was. but she could never feel that fiery passion she always read about. she only ever felt that with one … and they’re forbidden

“I’ll give you a world where you are my sun, and I orbit around you. Wherever you go, I will find a way to follow. Whether that’s here in the city, or anywhere else you desire.”

ugh i love estella and leo so much 🥹 they were separated for way too long before reuniting again. the way they both just immediately fell back into where they left off had me actually SQUIRMINGGG 😩 they’re such a filthy couple and i literally ate this the fuck up !!

This series of novellas is such a delightful, naughty treat.
The author has managed to toe the line between creepy and endearing in a wonderful way. Everyone involved is fully aware of how weird it all is, but they can't help themselves, and the tension between the main characters is chef's kiss.

It's no different between Leo and Estella, a pair that has had a secret relationship as teens due to their parents having been married. I felt for Leo, being stuck in their parental home due to agoraphobia.
Even though they're stepsiblings, I didn't have much trouble with this taboo pairing in this scenario because their parents got together when Leo and Estella were in their late teens.
The story is a little over 100 pages. Despite the size, it definitely felt like I'd read a full-size novel.

This was such a good spicy story! This story hooked me in right from the beginning and I loved every single bit of it! If you have read the other books in the hot creeps series then this one is a must read as well! Definitely a 10/10 read for me!

Estella is really out here living her life and trying to avoid the most delicious of guys. I wasn’t sure I would like this one but holy cow! the spice was spicing! The back and forth between the two main characters was really good!! Effie writes the most delicious tension.

Leo is a recluse, living in his parent’s attic, where he’s designed the entire top floor into everything he needs; bedroom, bathroom, work station, and access to his many cameras stalking his obsession- his step sister Estelle.

With their parent’s anniversary coming up, Estelle is finally coming home, for three days, with her passion lacking boyfriend, Graham. She’s cautious of her stepbrother, knowing his obsession for her is off the charts.

Will she survive Leo?
How would her parents react?
Is Graham what she truly wants?
And IF she wanted a relationship with Leo, could he give her what she needs outside the bedroom?

Being a recluse myself, I felt so bad for Leo. I didn’t like when Estelle called him a loser, or threw the fact that he lives in their parents attic in his face.

But the sexy times were great. I loved how Leo worked his way into Estelle’s mind, making her realize that she was just as into him as he was in to her. I was so excited whenever Leo finally left the house, and reading about the life they lived together.

I’ll have to read more from this author because this was pretty damn good!

This one is a forbidden step-sibling romance with an obsessive possessive reclusive stalker MMC. All the things we want in our FICTIONAL morally grey men!!
Can’t say I’ve ever read a book that had a MC with agoraphobia (fear of open/crowded places or leaving one’s home!) and it was somewhat interesting.
I enjoyed this one and couldn’t put it down! I mean the pantry scene? Yes please!

🌶️🌶️🌶️🌶️/5

“𝓨𝓸𝓾’𝓵𝓵 𝓫𝓮 𝓶𝔂 𝓯𝓲𝓵𝓽𝓱𝔂 𝓰𝓲𝓻𝓵 𝓯𝓸𝓻𝓮𝓿𝓮𝓻.”

This forbidden romance novella is book 3 of the Hot Creeps series. The content, both on and off page, will NOT be suitable for everyone. It covers topics that are dark and may be triggering to some. You MUST proceed with caution; your mental health matters.

Effie is the gift that keeps on giving with this Hot Creeps series! I must say, this is my favourite so far! I’m a sucker for a forbidden step sibs romance 🫠

Leo is obsessed with Estella and has been since he first laid eyes on her. He is determined to make her his, no matter what it takes. Estella has built a good life for herself with her boyfriend Graham since she last saw Leo. Will returning home for her parent’s party blow a hole in her plans and bring up memories long since buried?

This was the perfect novella; the plot was intriguing, the spice was spicing and the feels were definitely present. It was fast and downright filthy. The tropes packed into this read were delectably delicious! I’m not normally a fan of cheating but I despised Graham that much I was actually rooting for it!

I adored Leo so much, I fell for him fast. Effie has this way of writing her MMC’s to be loveable in a forbidden dirty way; you know you shouldn’t love them but you really do and can’t stop it. His version of love was just different and one particular scene broke my heart 😭
I struggled with Estella to begin with as I thought she was a bit of a wet lettuce but when her naughty side came out, holy crap…
Graham, we don’t like him. That’s all I’m going to say.

Would recommend to anyone on the search for a short and filthy read!

EFFIE!! MAAM CAN I PLEASE VACATION IN THAY BEAUTIFUL BRAIN OF YOURS?!

I absolutely LOVED Such A Filthy Girl! It's forbidden, taboo, and just down right delicious!! From paying top dollar to habe cameras installed to literally having the freckles that adorn Estella’s face and having her nickname TATTOOED on his 🍆 Leo has rightfully taken the top spot as my favorite!!!! And don’t even get me started on the peep hole IYKYK!!!!

Personally I feel like Estella should have left her P. O. S. boyfriend in the beginning. It felt like she was holding out on her own happiness because she was with him out of obligation AND not to mention him bringing her down for her wanting to spice things up! Hands down he was a complete jerk and deserves whatever happens to him!!!

The ending was super sweet!! I loved how one faced their fears in order to be with the other and then finding out that their love conquers all!!!

If you haven’t read any of the Hot Creeps series by Effie Campbell, I HIGHLY recommend that you do!!!

My Review:
5 ⭐️ 3.5 🌶️

Such a Filthy Girl by Effie Campbell is the literary equivalent of a guilty pleasure you never want to admit to, but secretly crave. Leo? Oh, he’s the king of stalk you until you fall in love vibes, trapped in his agoraphobic lair, watching Estella like a love-struck ninja. When she has no choice but to return for their parents’ anniversary, Leo’s ready to claim what’s his — boyfriend be damned. Estella’s got her “normal” life, but we all know she’s really craving the chaos Leo brings.

This novella serves up forbidden lust, tension that could cut glass, and enough spice to make you need a fan. Leo is a red flag wrapped in a very hot package, and honestly, we’re all here for it.

Effie, please, I’m begging you: can I get my own Hot Creep? Because I need a Leo in my life, stat. This series? Unstoppable.

‘I’ll give you a world where you are my sun, and I orbit around you. Wherever you go, I will find a way to follow. Whether that’s here in the city, or anywhere else you desire.’

Oh this has easily been my favorite of the series. Leo is a crazy stalker but I'm here for it. The fact that it's for his stepsister makes it even hotter. Hey, don't judge.

I did the audiobook !

Listen… at the point you throw a step brother trope at me and I’ll eat it up. Add in the fact that he’s a little delulu for coco puffs and unhinged? YEP

Effies never misses. When you are in a slump the way I am and need something quick. Fun AND FILTHY pick one of her audios up!!

Effie Campbell's smutty novellas are literally the perfect palette cleanser! After being on a heavy romantasy train this entire month, this novella was the perfect refresher. I do absolutely love a taboo step-sibling trope and boy was this one dark. From the moment we start this book, we're in the action - there is no time to settle, you are hit with Leo's obsessing full force.

I really loved the whole agoraphobe angle this book had, I haven't read one before and I enjoyed experiencing it. I loved his determination and his utter confidence even though he obviously struggles with this disease. His obsessed with Estella had heavy stalker vibes and was borderline psychotic but gosh-daymn it was hot as hell.

I loved the family reunion vibes and the fact that Estella brought her, very obviously, not-for-her boyfriend along. It made the forbiddenness between hers and Leo relationship all the more real. Watching Leo struggle with his disease in order to be the man Estella needed was really cool and I really enjoyed this book!

cute

Quicker cute dirty read. Decent story w a decent size plot with a lot of steam to factor in. Both characters work and aren’t annoying but in general it was just a cute story. Nothing to crazy.

Short and Spicy 🌶️

Sometimes I just need a short spicy fix after reading a plot heavy book/series and this series of books never disappoints!!
Now there is very little plot, they all contain a short storyline with A LOT of spice, smut, kinks, taboo scenes - you name it, it’s probably in one of the books

This book follows Leo and Estella, step siblings who haven’t seen each other in 6 years. Leo cannot leave the house due to the nature in how he lost his mother. Estella moved out, went to college and found a boyfriend (boring Graham as I like to call him). He doesn’t provide Estella with everything she needs … wink wink. 🤭 Leo is OBSESSED with Estella and goes to extreme lengths to fulfil his obsession. He gives her everything she needs but will the taboo nature of their relationship stop her from being with him?

Loved this book, the spice is written soooo well and hits the spot!!

2.75 ⭐

Okay so I love a good forbidden step siblings trope but this one didn't fully hit for me, I enjoyed this novella and it would have been a 3 star if it wasn't one of those that use the brother or sister thing in the spice for example one line said "Quiet love, unless you want them to find your brother knuckle deep inside your sopping cunt" And i'm just not personally a fan when that type of thing is really focused on especially in the spice so that just rubbed me the wrong way and the FMC Estella I just couldn't fully like or connect to her, I just found her to be quite annoying with the back and forth between graham and Leo, I did like Leo however and i'm happy that he got his happy ending even if it was rushed but I am happy to see him happy, overall a fun and entertaining spicy novella

Tropes:

Step-siblings

title = Such a Filthy Girl
author = Effie Campbell
page count = 168 - Kindle edition
when did you read it = June 17, twenty-five / twenty-six [re-read] / August 28, 2026
series = Hot Creeps
number in series = three / six
genre = dark romance
rating = four / five

summary = Leo has been obsessed with Estella since he first laid eyes on her, and that's when their parents first met. He is determined to make her mine, and nothing will get in his way. Not their parents, not her useless boyfriend, and not his fear of leaving their parents' house. Leo has been living upstairs in their parents' house till his mom passed away. He has built his life up there with everything he needs, but one thing is missing- his woman. His business pays really well; it's not like he's broke and a nomad living up there.

And Estella is coming home for their parents' anniversary party. And there's no way that he's just going to let her go again.

Thoughts / rated it = I've read this book a couple of times; the most recent was yesterday. I've been on a hook for short, smutty reads here and there. Haven't been able to get my head in the right spot for a longer book. This book is almost a comfort book...lol. I have 146 annotations in this 168-page book. Leo is such a sweet guy.

[ spoilers ---------]

The dedication was adorable, and learning what it meant later on- I want someone who has my freckles tattooed on them. "If you’re looking for a man so obsessed with his girl that he tattoos her nose-freckles over his heart - you’ll adore Leo." Whenever they were younger, they spent a night on the roof looking at the stars. They shared a night where they kissed under the stars, and she tried to forget about it - he, however, repeats that night over and over again until he can get it again - the real thing over and over again. Leo is a spicy stalker; he watches her in her apartment, photos, video clips, and streams of everything she does, including fucking her incompetent boyfriend who doesn't know how to get her off-nor what she wants.

or when Leo was so needy on wanting her but couldn't have her, so he got an escort that looked like the closest to Estella- now some people aren't okay with this trope - but I didn't mind it. "Maddie’s heels clipped on the back stairwell, echoing up into my sitting room. Closing my eyes I imagined that it was Estella, that she was coming home to me. The image died when she pushed open the door and laid a sultry smile upon me. Estella’s smile wasn’t like that. Maybe it was for Graham…but never for me. Her smile was softer, more open. It reached her eyes. Maddie shared a lot of similarities with Estella, she was the closest look-alike I could find"

‘Quiet, love. Unless you want them to find your brother knuckle deep inside your sopping cunt.’

‘Come for me, Estella. Be my filthy girl.’ ‘Leo,’ she moaned, her pleasure becoming more vocal with each circle of my thumb. Too loud.

"Another partygoer stumbled into the room, dragging her friend along with her. We pressed backward to allow them in, Leo moaning under his breath as his cock slid against my panties again and again."

‘I have starshine etched on my dick. Marking it as yours if ever you’ll have it.’

tropes = taboo, dark romance, forbidden, step-siblings, cheating, stolen touches, possessive partners, second chance, enemies to lovers, death, grief, dark themes, nicknames, he falls first, he takes care of her, opposites attract, forced proximity.

kinks = bdsm elements, stalking, dubcon, somo, breeding, obsessive mmc, cock warming, dirty talk, praise, size difference, anal, taboo.

Written = August twenty-nine, twenty-six
