Would you enter a chance to win $6 million just by exchanging your time for 30 days in a hotel completely isolated from the outside world. Sounds easy, of course. But not when you’re using it as an escape after watching your ex-husband murder his coworker. Rachel spirals into a complete psychological breakdown as our days begin to blur reminiscing on past events she slowly begins to lose herself. The tension builds perfectly in this thriller, leaving you to wonder what the hell is about to happen. Is what is happening to her new reality or is it just all in her head? Who knows. But is it worth 6 million to you? Highly recommend do not disturb.

Ooo this one messes with your head—in the best way 😵‍💫 Wow! Nadija Mujagic delivers a mind-bending, mind-blowing psychological thriller that constantly keeps you guessing. The tension builds as paranoia sets in, and just when you think you understand what’s happening, everything shifts. Make sure you read this before deciding whether you would accept the challenge—because it may not be as simple as you think.

[Denise Little · Rating 5 out of 5]

Could you spend 30 days in isolation and no contact with the outside world for $6million? Rachel thought it was going to be easy. Then the rules keep changing.

This was an astonishing thriller! I absolutely could not stop reading, I avoided chores because I had to know what would happen! Nerve wracking in the way we love with thrillers and a very unexpected twist!! A must read. I’d give ten stars if I could.

Release date February 19, 2026

Do Not Disturb by Nadija Mujagic
🌟🌟🌟🌟🌟
Wow!!!! This is one of the most unique and exciting psychological thriller books I’ve ever read!!!

This story is filled with twists, turns and so much excitement and suspense! The premise of the story is fantastic, and as a reader I went into the book already feeling eager about reading it! The intensity of the story never lets up!!! I did not want to stop reading, as it is so engaging and left my mind spinning!!! It’s very well written and super entertaining!

The story has dual timelines with multiple POV.
Rachel Browning, who is newly divorced, is trying to rebuild her life when a mysterious offer comes her way. She is presented with an unbelievable $6 million to stay in a hotel for 30 days. There are a few simple rules she has to follow in order to receive this phenomenal payout. Rachel figures this money would change her whole life and how hard could 30 days really be?

Felicia Mebane and her husband are living a happy life, until one day Felicia feels she has witnessed a possible murder. This turns things upside down.

There are several places in the story where my jaw dropped and I was floored at what I was reading!!! I was completely guessing up until the end of the book! The thrills and entertaining storyline doesn’t let up through the entire book, and my mind was all over the place with guesses, that I never got right.

Nadija Mujagic is an absolute must read author!! I’ve been so lucky to be an alpha reader for her. It’s amazing to read these creative and outstanding stories she puts together.

This book comes out February 19th, and is an absolute must read!!
*Run to grab this book!!!*

Would YOU accept this offer? Six million dollars to spend 30 days in a Motel. By yourself. No phone, computer, visitors, music, or clock. Just books and magazines?

Rachel Browning was broke and alone. She had nothing to lose, right?

Except her sanity....

The challenge changes, as do the rules. Rachel's mental health spirals. She starts to imagine things. The people in charge become scary and ambivalent to her needs. Days blur into nights. Nightmares from the past haunt her.

Will she last the 30 days???

This book deeply explores the mind, especially when reality and imagination are indistinguishable. A mind-blowing thriller full of gaslighting and paranoia. It gave ME anxiety, which never really let up, I was fully invested in this book. WTF was I reading?

The intensity built up throughout and stayed until the end. A very unique story that pulled me right into it.

The Mind is very powerful indeed!!!!

Thanks Nadija, my 14th book of yours, and I have loved every one of them. Your writing is extremely deep, descriptive, and enabled me to 'feel'. I honestly thought that spending 30 days in isolation with just books - for six million dollars - would be 'heaven' lol.

I'm not so sure now... 😱

[Danielle Lundquist · Rating 5 out of 5]

This book was an absolute 5 star 🌟 for me.

Rachel is used to the finer things in life that her husband (Roger) could provide, she has limited working experience since her husband always took care of everything. They divorced and he left her with nothing. She’s struggling financially and mentally. She receives an offer that she can’t refuse and receive 6 million dollars for completing the challenge. The only rules are no phone/internet. Slowly the rules change. Can she complete the challenge?

Feleca and Roger are married. He is always spoiling her and treating her to a whatever she wants. Eventually he breaks the news that he can’t keep affording her this lifestyle and it seems that triggers some trauma from when she was a kid.

I thought I had this figured out, but I did not. Be prepared to read it in no time, just to get answers! I had anxiety for Rachel so be prepared to have it too!

⭐️⭐️⭐️⭐️.5

I read this as an alpha reader and provided early feedback; this review reflects my honest opinions.


This book stressed me out in the best way.

Do Not Disturb follows a woman who agrees to stay in a hotel room for 30 days — no phone, no contact, no outside world — in exchange for six million dollars. What starts as isolation quickly turns into something far more sinister.

The gaslighting in this book is intense. I genuinely felt like I was losing my mind alongside the protagonist. The short chapters keep the tension high, and the story wastes no time pulling you into the chaos.

I read this in a day and a half because I had to know what was going on. This is my second book by Nadija Mujagik, and she’s quickly becoming an author I trust for anxiety-inducing psychological thrillers.

Highly recommend if you like claustrophobic, mind-bending reads.

[Thriller Lover · Rating 5 out of 5]

Oh my goodness. This book gave me so much anxiety reading it. Rachel accepts a challenge to spend 30 days in a hotel room with no connection with the outside world to win $6 million. She accepts the challenge, because she just got divorced and she's broke. But things don't go as well as expected. So much happens in one room -- gaslighting, questioning, fearing for her life. And the twists are just insane! HIGHLY RECOMMEND this book!

[Bookdragon_Lady · Rating 5 out of 5]

I was hooked right from the start. As a mom, I would jump at the chance to do nothing but read, eat, and sleep for 30 days. So as I read she was offered 6 million dollars to spend a month in a hotel with no outside contact for 30 days, I would've jumped on that opportunity. But what would you do if you start seeing things?
Hearing things? I don't know where Nadija drew her inspiration for this story, but this was a nice, fun, twisty ride that I just couldn't put down.

[Gina · Rating 5 out of 5]

Nadija Mujagic masterfully blends emotion with psychological tension, constantly blurring the line between reality and imagination. The deeper you go, the more you start questioning the character’s mental state. It keeps you second-guessing everything right up until the very end. Unsettling, gripping, and impossible to put down.

[Brandie Miller · Rating 5 out of 5]

“Do Not Disturb” was fantastic! I couldn’t put this book down!
It had so many twists and turns that had my jaw hit the floor.
Everything in this book was unexpected, from start to finish.
I definitely recommend reading this book!!

[Mandy · Rating 5 out of 5]

Claustrophobic, tense, and razor-sharp, Do Not Disturb twists isolation, control, and doubt into a relentless, nerve-fraying thriller. Nadija Mujagic keeps the pressure high and the unease constant, blurring the line between endurance and unraveling.

[Sejla Velic · Rating 5 out of 5]

What would you do for 6 million dollars?!

This one had me feeling super tense with my anxiety at an all time high. It’s like when you’re waiting for that jump scare when watching a horror movie. The build up and pace was amazing and I couldn’t put it down. Highly recommend this one!

[Tracey Schuler Rogers · Rating 5 out of 5]

Another unputdownable thriller from Nadija!
Do Not Disturb kept me asking myself what did I just read?
Every time I read one of Nadija s books, I feel as if I have been transplanted into the story. It feels as though you are standing alongside the main character as the story unfolds.

[Nina · Rating 5 out of 5]

Great read, always recc Nadija’s books.

[Melissa · Rating 5 out of 5]

[Tara Leigh · Rating 4 out of 5]

Such an intriguing idea at the heart of Do Not Disturb. This book really made me stop and think about choices, consequences, and the lines we’re willing to cross.
