In Between

Sinner or Saint #1

by L. Luisa

In a world of sinners and saints, the most dangerous thing is falling for both.


Nora Westfield has spent the last year picking up the pieces—grieving her father’s death, burying herself in law school, and swearing off men entirely. Then a stranger saves her from her ex in a dark Boston alley and turns her carefully controlled world inside out.


Nikolaos Regas is magnetic, protective—and hiding something dangerous. When he walks into Nora’s law firm as the defendant in a high-profile blackmail case, everything begins to unravel. The deeper Nora digs, the more she realizes Nick isn’t the only one keeping secrets—or the only one watching her.


There’s another man. One who finds her curled up on a cold floor and carries her out without asking permission. One who calls her Snow White and looks at her like she’s the only thing in the room worth breaking. One who knows secrets about Nick that could destroy everything.


Two men. One devastating secret. And a woman caught in between.

All the characters and layers were great. I enjoyed the book.

I loved this story. All the characters and the layers. The way everyone has a connection somewhere is great. The thrill in this book was great. No spice factor really and I was okay with that the characters kept me interacting can’t wait to read the next book I received an advance review copy for free, and I am leaving this review voluntarily.

I had so much fun reading this book! It took me less than half a day to finish because I was so invested in the story and just had to know how it ended. I’ll get you for this cliffhanger, girl!! 🤣🤣
It’s such a shame the second part doesn’t come out until next year 😔

I was really surprised by how well the author managed to merge the story from four different POVs — that usually gets messy and confusing, but not in this case! Each perspective was clear and added something important to the plot.

The story is super fast-paced and totally addictive. You keep telling yourself “just one more chapter”… and suddenly you realize you’ve finished the whole book 😅

When Nora, a legal intern, is saved from an abusive ex boyfriend by a man named Niko she never imagined that she would be assigned to work on his case.

This is a slow burn, romantic suspense with seedy businessmen, secrets and lies, a complex love triangle, set in a dangerous world. I thought it was pretty good, the inner-monologue of the fmc did drive me a little nuts. She second guesses herself a lot and most of the time focuses on the negative aspects of the person, giving her a “ I’m better than you “ attitude. I realize some personal growth needed to happen with the characters in this book. Overall it was enjoyable. This ends on a cliffhanger.

In Between is for you, if you're looking for a book that has:
Dark secrets
Slow-burn chemistry
Betrayal
Lawyer/defendant
Family Trauma
Corruption & Blackmail

The book is in the POV of 2 MMCs and 2 FMCs and it worked out so well. smooth transitions between so many POV's isn't always there, so kuddos to this new-to-me author as they did a great job.
Each Character is developed so well and their interconnectedness was perfect.
There is no spice, but their feelings burn slow but high.
I am looking forward to Book 2 as their story may not be finished after all.

I received a free ARC of this book and this review is only my opinion

I received an advance review copy for free, and I am leaving this review voluntarily. It did take me a while to complete this book, but not because it was a hard read. This book had such a good story line that made me want to keep coming back for more. There is a little bit of smut in here, but not a whole lot - so if you are into smut, this may not be the first on your list to read. While reading this book, I was constantly going back and forth between whose side to be on - Zeno or Nick. Both have their good attributes. Nora, the main character, also went back and forth between Zeno or Nick. Who will she choose??

I can’t wait for the next book to come out, since this one ends on a cliffhanger!

[D.3.b.0.r.a.h · Rating 4 out of 5]

I had a bit of a hard time getting into this book at first, but I'm so glad I kept reading.

The further I got, the more intrigued I became by the mystery surrounding the characters and all the secrets waiting to be be uncovered. The tension was done so well, and I loved not knowing who I could trust.

Nora's journey kept me invested, and both male characters had me equally curious for very different reasons. The slow burn, the suspense, and the constant feeling that something bigger was lurking beneath the surface made this a really enjoyable read.

And that ending?! I definitely need the next book.

I found this book to be a really good read. I loved how they characters were so well detailed, they had depth that made them more realistic. I also like that all the characters were interconnected in someway.

There's limited spice in this book, possibly building into book 2, but we shall see. There is a heck of a cliffhanger so be ready to wish for book 2.

This book just took me out of my reading slump!

Amazing plot that kept me engaged from start to finish!! I literally couldn't put it down!!

The smut is there, but not overly shadowing the development of the story!

Couldn't choose who's my favorite MMC throughout the book!!

Excitedly waiting for the next book!

I absolutely ate this book up!! It was amazing, the storyline was so intense it kept me hooked the whole way through. You never know which way it will take you and keeps you guessing. The characters were incredible and I loved that you got to know more than just 2 main characters 😍 after that ending I am super excited to read book two when it comes out!! I need to know more😍

[Le Incrediblè · Rating 5 out of 5]

I love how all the characters are connected, it’s my first time reading dark romance and I have to say I was very impressed by the writing and depth of the story. Zeno is very unique and I love how Nora evolved without losing who she is! Can’t wait for part 2!

[Dee Layton · Rating 5 out of 5]

This was a very good book. It was a very smooth rad that kept me interested to the very end. I love how it was a very med paced book and the character were strong. The way the author built up everything was just beautiful.

[Blake Turner · Rating 5 out of 5]

I absolutely loved this book due to how well it was written,the structure was stable despite it having multiple povs which can tend to make the story hard to follow but it didn’t it was done really well. The plot was also refreshing and very different which made me enjoy it even more

[Tess R · Rating 4 out of 5]

The book is an easy and enjoyable read. It had some really fun and unexpected elements that kept me guessing—I couldn’t predict how the story would unfold, which made it even more engaging.

OMG, I’m going straight on to the next book—I need to know what happens next!
