The Wrong Obsession

One Savage Touch Duet #1

by E.L. Sparrow

She spent ten years loving the right brother, only to fall for the wrong one in one weekend.

Sloane Mercer has been in love with her best friend, Finn Hartley, since college. For ten long years, she’s been the one stitching him back together every time Delilah Crestfield—his toxic, on-and-off girlfriend—ripped him apart.

When Delilah announces her engagement to another man, Sloane finally sees her chance. But instead of moving on, Finn decides to crash the wedding and fight for Delilah one last time, and he wants Sloane there to help him do it.

She agrees, hoping that maybe this time, proximity will make him see her the way she’s always seen him.

Then she meets Knox Hartley.

Finn’s older brother is everything Finn isn’t: cold, calculating, and unapologetically dangerous. Knox sees straight through her quiet devotion and makes it his personal mission to unravel every defense she’s ever built.

What starts as a twisted game between them quickly becomes something neither can control. And Sloane finds herself caught between two brothers: one who’s spent ten years breaking her heart without knowing it, and one who seems determined to claim it no matter who gets destroyed in the process.

NOTE: This is a steamy, emotionally intense romance with adult themes, morally complex characters, and scenes not suitable for sensitive readers. While it's funny, dramatic, and chaotic for the most part, reader discretion is advised.

Literally could not put it down. This book had me feeling EVERY emotion, hot and bothered, endearment, RAGE, and others. Found it on a Facebook reel, read the first few chapters in the post, then SEARCHED the interent for the full book because I was already OBSESSED. I don't think I've ever felt this level of addiction to a book before (fitting 😆). I will be refreshing my socials multiple times a day to catch the release of the sequel!!!

I love Knox and Sloane's relationship... no matter how crazy and fucked up it got. I was HOOKED.

This was recommended via Reddit so thought to check it out when lo and behold, I realized I had actually read this before.

This book was actually titled Craving the Wrong Brother under the name Elysian Sparrow. Same story though.

I remember being immediately hooked and it was fast paced with some real good smut. Hated Finn, Delilah and the mom who were some of the most childish and selfish people ever.

The way Knox honed in on Sloane was yummy. Our girl was a firecracker while MMC was tall, dark and handsome. He went through some things during his time away in the military before coming back and climbing his way to the top.

Good pacing and story was engaging. I don't typically re-read since there's so many exciting stories out there but I re-read this one a few times and it hit every time.

Safety - both non virgins, he didn't come off as a manwhore but he did have a sex room 👀, OWD (he's technically married and she really wanted to give it a shot but they never slept together), OMD (she was in love with the brother), no cheating, no sharing, no on page sex with OP.

Omg. I absolutely loved this book. I started reading as it was an ad on facebook and instantly got hooked. I found where to purchase it from the author and bought it. I could’t put the book down. The way this author writes just makes it so easy to read. The descriptive wording that they used, it was like creating a movie inside my head which I’ve never felt before when having to read. This is the first and official book I’ve completely fell in love with. The book is basically about a woman named Sloane and her best friend Finn who is completely obsessed with a toxic woman (but you will see its very fitting for him as i feel he’s just as toxic and psychotic). Then they introduce a guy named Knox. Knox is Finn’s brother and they absolutely hate each other. Can you guess which one she falls deeply in love and obsessed with?
Im so sad i finished the book so quick!!! Im so excited for the second book to come out soon!
Here is a comment i left on the authors tiktok page that explains my newbie review on a book😅

I just have to say, i never read books. My entire life i have had problems being able to sit down read a book and understand what im reading. I could never comprehend it and remember it without rereading the same page over and over again. I also always needed a ruler or something to help me with my eyes moving to different lines by accident. Come to find out i have adhd and a form of dyslexia. My letters move and my lines move. I was scrolling on facebook and an ad popped up for your book and had the first 3 chapters in it. Im not sure why i started reading it but i was curious. It instantly caught my interest and i read all 3 chapters and immediately went and found out how to purchase your book. The way you have written your book is just so perfect. I cant explain how amazing this book is. Thank you for showing me i can sit down read a book. You might have changed my life and i actually mean that.

I got sucked into this so quickly that I devoured it in less than a day. I stayed up reading and did nothing but finish this on my flight.

There's just something about Knox that makes me swoon. The way he is unapologetically himself and knows what and who he wants. I also just love how he treats Sloane. Finn frustrates me a lot and his indecisiveness and attitude about Delilah and Sloane had me tearing at my hair. Sloane is such a fun fmc. I really like the way she is when interacting with Knox and their chemistry and banter had me blushing and giggling. I really do appreciate the level of communication between the characters.

Did I download book 2? Yes. Yes I did.

This book is one of my favorites I was hooked from the first chapter! I love the characters it makes me feel like I am in the book seeing everything happening and i love it! I can’t wait till the second book!!

[Jessica Miller]

I loved this story so much and was more than happy to pay for a copy. I’m waiting to buy a physical copy u til it’s got a good edition with splayed edges. The story between Knox and Sloan is sweet and the sec scenes are hot and spicy. Can’t wait for the second o e.

[Line Zederkof]

I love this story, I can't wait for the next book <3

[Ashlyn]

LOVED this book so much

[Merrin]

This was unexpected. I started reading this book on one of those book apps and was hooked. Rather than waste my money on coins in the app, I decided to pay the author instead and buy the ebook. Best decision! Great storyline with added spice. Loving the story and can’t wait for book 2.

[Reader]

Read this book first and also just finished My husband wants an open marriage. Both books were AMAZING!!!! Looking forward to more books

[Ericka Puskar]

I’m obsessed! I found this book by random on a Facebook ad and got hooked right away then couldn’t put it down. It’s a must read! Very spicy!

[McKayla]

Definitely a good read! Couldn't put it down and I'm a little upset with myself for reading it so fast.

I originally read this in 2025 (like the day it was released practically), and I reread the last 5 chapters in 2026 when The Right Addiction dropped (again, practically the day it released), so I could get a refresher and I forgot how good this story flowed! There are really, really hot n' spicy sections followed by a dramatic twist here and there. It really seems like Knox's dark and crazy mixes well with Sloane's hot and nerdy. Sloane is a feisty, jealous little thing and I love it.

Still a 5 star read for me!

This book may only work for you if you have a fondness for the heyday of erotic romance/Fifty Shades. It has all the trope hallmarks: wealthy hero who uses BDSM as a way of treating PTSD rather than going to therapy, playrooms with a red aesthetic, scheming friends and family who have no care for the main couple. You get what I'm saying?

This also started as a serial on a romance novel app where you pay for chapters. I think this one had 150+ chapters before it concluded and is now a duology. You can definitely tell as the chapters tend to feel like vignettes that end on a cliffhanger, rather than a contained plot with characters moving toward something.

That being said, I did have a good time because of the first point I made. It's soapy and ridiculous and it started out really strong. It does become a bit rinse and repeat the longer it goes on. I'll probably pick up the second book when it releases, just to see how it shakes out. It's honestly cheaper than pay per chapter in the app.

[Hanna Desheles]

I LOVE THIS BOOK!!! From the first page I was absolutely hooked. I love the flow of the writing and the characters different perspectives. Every twist an every turn keeps you waiting with anticipation to see what happens. I even got my Husband hooked on this book!!!. He is former military and loves how it is tied into the story .The spicy scenes are written beautifully from both characters Perspectives. it really pulls you in. All the characters are so relatable I think that’s what makes this book obsessively good.
Dear E.L. Sparrow if you ever do read this review please please WE NEED MORE KNOX AND SLOANE!!!!

[Cheyenne]

I read this book on so,e kind of app and when I saw they was making this into a two part book, I had to get it!!!

Everybody need a Know and Sloane in their lives. I love their dynamic and very spicy scenes.

I love some of the other characters but just know some of them do need to disappear.

I can’t wait to read book two of this!!!! Going to get started right now.

[Deana Ashley]

Easily fell in love with the authors writing and greatly enjoyed reading this book. Can't wait for the next one!
Highly recommend this book for everyone to read it's that good!!

[Alyssa]

Kept me on the edge of my seat,wanting to know what craziness was around the corner between the main characters. Can't wait for part 2 to come out to finish the love triangle saga.

It made me fall in love with reading.
I have Sloane and Knox in my heart. Their relationship was the best I ever read of.

[thelisa.ɤ]

started off good and then i was like "why am i still reading this?!" but they got me again near the ending so guess i gotta read the next book as well

[Erica]

Found this on Facebook and was hooked. Searched all over for it and then bought it so I could read it all at once instead of on the apps. I was hooked immediately and devoured the entire book very quickly. I love Knox and Sloanes characters and Finn well… he’s like a you love to hate how frustrating he is type of character. The spice in this is great and the soapy drama is addicting and really keeps your attention reeled in.

[Abi]

Loved!! couldn't put it down! Can't wait for #2

[Theresa Perry]

I really enjoyed this book, I read it far too quickly!! The sex scenes are heavy, and some a bit too extreme for me but that absolutely didn't take away my enjoyment of the story. I cannot wait for the second part to come out so I can see what happens between the main characters!!!

[Katee]

Edit to add: impatiently waiting for the release of the second book. 😭

I can’t even begin to explain the thrill reading this book gave me. Knox and Sloane’s chemistry was so addicting to read. I need the second book right now 😫
