‎“ʏᴏᴜ ʜᴀᴠᴇ ɴᴏ ɪᴅᴇᴀ… ᴡᴇ ᴀʟʟ ʜᴀᴠᴇ ꜱɪɴꜱ ᴡᴇ ᴡᴏᴜʟᴅ ʟɪᴋᴇ ᴛᴏ ɴᴇᴠᴇʀ ꜱᴘᴇᴀᴋ ᴀʙᴏᴜᴛ.”
‎— 𝕲𝖗𝖆𝖈𝖊.

‎💚 A new pastor with not-so-holy thoughts
‎💚 She's a parishioner trapped in an abusive relationship
‎💚 First person dual POV
‎💚 Sweet "good" girl × naughty accidental stalker
‎💚 Boyfriend? You mean obstacle?!
‎💚 Blackmail and revenge
‎💚 A twist you won't see coming

‎One of the signs that a book is good is when it leaves you speechless after you close it ... And Her Favorite Sin is one of those books!

‎Short, spicy, and full of surprises, I honestly thought this would just be another ordinary erotica where two people look at each other and then goes into OMG I WUV YOU 😍😍 phase two seconds later.

‎And, for the most part ... I was right.

‎Since this is a novella, don't expect a slow burn. The relationship between the girls is very much instalove AND instalust, with a touch of religious themes ... And sapphic romance. But who doesn't love a little taboo? 😏

‎"𝘼𝙢 𝙄 𝙜𝙤𝙞𝙣𝙜 𝙩𝙤 𝙧𝙪𝙞𝙣 𝙢𝙮 𝙟𝙤𝙗 𝙞𝙣 𝙩𝙝𝙚 𝙥𝙧𝙤𝙘𝙚𝙨𝙨 𝙤𝙧 𝙩𝙖𝙧𝙣𝙞𝙨𝙝 𝙢𝙮 𝙛𝙖𝙞𝙩𝙝?"

‎Hope and Grace are drawn to each other from day one, and their love train was moving so fast that by the second day after meeting, nothing they did surprised me anymore 😂 At times, it pulled me out of the story bcs as a proud member of Team Slow Burn, I kept thinking, Isn't this a little too fast? Why are you thinking like this about a complete stranger?? 🤨 But yeaaah call me guilty.

‎I was mainly here for the smut ;))

‎"𝙄'𝙢 𝙨𝙩𝙖𝙧𝙫𝙞𝙣𝙜, 𝙖𝙣𝙙 𝙨𝙝𝙚 𝙞𝙨 𝙩𝙝𝙚 𝙤𝙣𝙡𝙮 𝙩𝙝𝙞𝙣𝙜 𝙩𝙝𝙖𝙩 𝙬𝙞𝙡𝙡 𝙣𝙤𝙪𝙧𝙞𝙨𝙝 𝙢𝙚 𝙣𝙤𝙬."

‎The middle of the book made me a little uncomfortable because of another character and a serious case of body betrayal syndrome. I was even tempted to DNF because I just couldn't stand that character. At the same time though, I was fascinated by how the author kept me asking, where on earth is this story going?? And the answer turned out to be somewhere I never expected 😳

‎While I do think some parts were a little OTT, and I believe this story would've worked even better as a full length novel, it still works perfectly as a quick, delicious snack. That ending absolutely got me. I literally had to reread it because, what do you mean she did that?!!! HOW? WHY?? 💀 Now I'm just sitting here trying to process the ending and wondering why I didn't start reading K.M. Avery's books sooner.

‎"𝙏𝙝𝙞𝙨 𝙘𝙖𝙣 𝙗𝙚 𝙧𝙞𝙨𝙠𝙮, 𝙗𝙪𝙩 𝙣𝙤𝙩𝙝𝙞𝙣𝙜 𝙬𝙤𝙧𝙩𝙝 𝙝𝙖𝙫𝙞𝙣𝙜 𝙞𝙨𝙣'𝙩 𝙧𝙞𝙨𝙠𝙮."

This is a dark sapphic romance - please read the content warnings

firstly, thank you K.M for actually making me say what the actual fuck just happened out loud with this book.

The story centres around Hope, a young girl stuck in a horrible relationship for the sake of reputation and Pastor Grace, the new Pastor who has a dark past and after seeing Hope sat in the front row of her first sermon, is obsessed with this seemingly sweet and innocent creature.

I loved the whole premise of this novella, it gave a very unique perspective on some of the classic tropes and I think this gave the story a whole new vibe you could sink your teeth into.
The pastor x parishioner idea gave the morally greyness of the characters a whole new level as you would not expect this kind of behaviour from devout church goers.

The DV situation surrounding Hope and Elijah seemed somewhat questionable and I think this lead to creating more tension and intrigue as to who knew what and on what level.
I enjoyed the whole manipulation between the main characters, it seemed like everyone had an agenda and with the small town trope, it was harder to tell who was on what side of the line, so this also added to the mystery and intrigue.

The love triangle was a more unusual take on the trope and Bo gives off certain daddy vibes but also a LOT of very red flag behaviour that has you questioning which way the story will turn.

The spice was well written and definitely made me hot under the collar but didn't take over from the story itself.

Now for the plot twists. Oh My God! There were moments when I though, oh I know what's going on here only to turn the page and completely wrong. I am still questioning what the hell I read and I want to know more about what happened after and how involved Hope's sweet and innocent Grandparents actually are.

Highly recommend this if you like short spicy sapphic novellas with a real twist.

*Review of advanced copy sent by the author*

What. In. The . World!

After reading the ending and then the epilogue, I laid in bed staring at the wall in a daze. I did NOT see that coming. Wowza. I was not prepared, at all!

Overall plot: ⭐️⭐️⭐️⭐️⭐️
Spice: 🌶️🌶️🌶️

A wonderful plot filled with revenge, betrayal, lust and lies. A few mvrders and seemingly cute love story… with a few twists so to speak.

The Pastor V Parishioner being FFM (no spoilers) was fanatic. I loved the dynamic between the two. I absolutely loved how the FMC (Hope) had her protection and her revenge and her “fun” too.

Thank you so much for my copy of Her Favorite Sin K.M. Avery! You have done it again! Another amazing plot twist! This book follows a pastor who moves to a new town to start fresh! She is no ordinary pastor though so don’t let her fool you!! She had no idea she would meet a parishioner that’s in an abusive relationship and is in need of saving. This a novella so this is not a slow burn and gets right to it!!

Welcome to Open Arms Parish where you meet Grace, Hope, and Boe. Grace arrives at the church to be greeted by members of the church who are there to help her move things into her new house. During the Sunday Service Grace is interrupted when a couple walks in late and comes face to face with Hope. The minute theirs eyes meet they can feel the chemistry. Hope is in a relationship with someone who abuses her and Grace immediately picks up on that when she goes to have a conversation with Hope. Grace knows it’s inappropriate and that she can’t do anything with Hope but she wants to help her anyway she can!

Hope was told to bring lunch to her boyfriend and if she does not she will be punished and not in a good way. When Hope gets there she is meet with something she didn’t know was going on. The minute she leaves she makes the tough decision to go to the Pastors house for help. Once there Grace reaches out to Boe for safety and he not only comes but so does Hopes grandparents.

Boe and Hopes grandpa decide that staying the night at Graces is the best decision to keep Hope safe!! Grace goes down to the kitchen to get something to eat for Hope and she notices a change in Boe. He is not happy about the way Grace is with Hope and blackmails her to get what he wants and that’s Hope! He is willing to let Grace be apart of it if she follows his rules like a “good girl”, but will she be able to do that? Do they want to be with him? Come to Open Arms Parish and find out!!

This book was one of my all-time favorites of perfect standing book from this collection

To start things off, I judged the book by the cover. Was absolutely scared to read it not knowing how I would feel about it but the way that we were introduced to Hope and Elijah and everything. Their relationship had gone through as a couple and her abuse in a relationship, mental and physical. We also then met Grace who was a pastor, one of higher standard that everybody would look to for guidance, Hope and trusting her and not so much using her position for influence, but knowing how to proceed with what she wanted and how she felt Grace was there to be the savior for Hope when needed. Meeting Boe who had been pinning over Hope since day one. The events in the book I will not go into, but I would read this at a.🌶️🌶️🌶️🌶️ on the spicy scale. Do you remember that there is a virgin in the book who does eventually lose her virginity. I will tell you there is a plot twist at the end of the book that I did not expect an event that happened.

This is my feeling on this book. Please read for yourself and tell us how you feel about it.

⭐️⭐️⭐️⭐️⭐️ ARC Review | Her Favorite Sin by K.M. Avery

K.M. Avery has a way of pulling you into a story and refusing to let go, and Her Favorite Sin is no exception. This book delivers an emotional roller coaster filled with tension, forbidden attraction, healing, and characters you’ll find yourself fiercely rooting for.

What stood out most to me was the balance between the romance and the heavier emotional themes. The chemistry is undeniable and full of slow-building anticipation without overshadowing the heart of the story. Every twist kept me turning the pages, and I was constantly wondering what would happen next.

The characters felt layered and authentic, making it impossible not to become invested in their journey. Watching them confront their pasts while searching for hope made this far more than just a romance—it was a story about finding the courage to choose yourself.

If you enjoy emotional romances with suspense, complex relationships, and plenty of angst mixed with heartfelt moments, this is one to add to your TBR.

Trigger Warnings:
• Domestic violence and emotional abuse
• Discussions of suicide and trauma

This book was crazy! It had so many twists and turns and the absolute most shocking ending that I did NOT see coming. 🤯

We follow Hope, who is trapped in an abusive relationship, living in a small town with what seems like very little hope that anything will ever change. That is until she meets the new pastor, Grace.

Grace is definitely not your usual pastor. This woman has secrets and she’s also falling hard for Hope. But Hope should be completely off limits, especially when a relationship with her could threaten Grace’s job.

These two go on one wild journey filled with romance, spice, mayhem, revenge and justice. There were so many moments where I thought I knew where this story was going, only for another twist to completely throw me.

I honestly can’t say too much without giving away spoilers, but that ending?! SHOCKED. I did not see it coming at all! You need to read this one for the plot twists alone.

What a crazy journey! 🤯

⛪ Pastor x Parishioner

K.M has offically became the queen of plot twists. That ending ... WHAT... I never saw it coming in the slightest. Im this book you meet Hope (Fmc) who's home life isn't for the faint of heart. Grace (Fmc, New Pastor) moves into town and sees what happening with Hope and wants to help. Will Grace save Hope? Or will Hope's life end tragically? You'll have to read to find out. I absolutely devoured this read with no hesitation and I highly recommend this be added to your tbr because this books plot twist is one to remember for decades to come. If you love a small town forbidden romance with a plot twist that'll have you yelling at night into the abyss then this is the read for you! If i could rate this a 7 out of 5 stars I most definitely would! Highly Recommend!!!!!!!!!!!!!!

What on earth just happened?

This story may be a short read but my god did it pack a punch....

Never go into a story thinking someone is so sweet and innocent because this story took me on a whole new journey that at the end I was actually staring at the wall.

The author managed to shock me with this plot and I was so here for the twisted story because it was absolutely amazing.

Never did I see that ending coming I absolutely loved the twist.

I can't say to much I'm trying to keep it spoiler free but I will say this gave going to church a whole new meaning.

I would highly recommend 👌

HER FAVORITE SIN
By K.M. AVERY

⭐⭐⭐⭐⭐


𝙏𝙝𝙞𝙨 𝙞𝙨 𝙖𝙣 𝙖𝙙𝙫𝙖𝙣𝙘𝙚𝙙 𝙧𝙚𝙖𝙙𝙚𝙧'𝙨 𝙘𝙤𝙥𝙮 𝙖𝙣𝙙 𝙧𝙚𝙫𝙞𝙚𝙬𝙚𝙙 𝙫𝙤𝙡𝙪𝙣𝙩𝙖𝙧𝙞𝙡𝙮.


The story is mind-blowing! Beautifully deranged!

And absolutely not for the faint-hearted.


I am amazed at how the story twists between Grace, Hope and Boe!

Never thought it would have such an unthinkable ending!

Maybe a little tweak to put some more details of Boe's ending just for a thrill.

Grab this little book if you're into something dark and sinfully grey! Don't forget to check your triggers.

Holy plot twist! I really didn't know what to expect going into this story, but K.M. knows how to get you hooked. I definitely did not see that twist coming that's for sure. I enjoyed the story between Hope & Grace. At first I was on the fence with the Pastor/Parishioner, since it's its a trope I've never read before. However, I didn't mind it, the plot was just too good. This is a shorter read so there is no slow burn and the spice was spicing. I still haven't been able to pick up another book after this one.

Her Favorite Sin sounds like an intriguing romance built around faith, temptation, and difficult choices. Grace stepping into a new parish only to have her biggest temptation sitting in the first pew is such a simple but effective setup. I’m curious to see how she handles the conflict between her desires and the oath she made. It sounds like a compelling read for anyone who enjoys forbidden romance and emotional tension.

This was a very interesting storyline about a pastor Grace who moves to a new town and comes across Hope, a young girl who is being abused. Grace and Hope feel something for each other but don't feel like they should.
Do they explore their feelings or just walk away. You will need to read the book to find out!
