Rate this book
Please this is Book 1 of a trilogy and ends on a cliffhanger. The full story unfolds across the entire series, so the books should be read in order to reach the conclusion.______________________________________________________________________________
The 1980 a decade when thousands of children vanished—and most were never found.


When six-year-old Charlotte Mercer disappears from her front yard in Silver Spring, Maryland, rookie FBI Agent Daisy Adams is thrust into a case that feels more like a haunting. There are no witnesses. No clues.

Daisy has seen horror before—but nothing like this. As the investigation deepens, so does her fear. Because every missing child reminds her of her own daughter, Lila. And the more she digs into Charlotte’s disappearance, the more she’s forced to confront the question she’s spent years

What if one day, it’s Lila who vanishes?

Inspired by real events, The First Thread is a chilling psychological thriller about the monsters hiding in plain sight—and the parents who live in fear of hearing the your child is missing.

THE FIRST THREAD BY NADIJA MUJAGIC.
5 ✨ ✨ ✨ ✨ ✨s
Release date set for the 25th of April 2025.
Book 1 of 3.
Based on a true events.
There's a few words to describe this book and I'd say it's chilling, creepy and heartbreaking at times.
I have been on the end of my seat the whole way through reading this.
It's a dark crime thriller that grips you from the very beginning and keeps you fully engaged throughout.
Such a gripping book that I didn't want to put down.
I'm looking forward to seeing how it all unfolds.
I honestly cant wait for book 2 and 3 I need them like NOW.
Brilliant nadija. Just brilliant

I just finished The First Thread, and my heart is still somewhere on page 214. Set in the 1980s—when missing kids were on milk cartons and fear was a daily guest—this story follows rookie FBI agent and single mom Daisy Adams as she tries to find six-year-old Charlotte Mercer, who vanishes from her front yard like a ghost.

Daisy is raw, real, and running on fumes. She’s juggling a full-blown FBI case while trying not to imagine her own daughter disappearing next. I felt her panic—like a punch in the chest and a pit in the stomach, all at once. It’s that kind of book.

Nadija Mujagic doesn’t waste a word. The writing is fast, sharp, and hauntingly simple. Every chapter cranks up the tension until you’re flipping pages like you’re being timed. And if you’re a parent? Buckle up. This one hits close to home in the most chilling way.

It’s gripping, emotional, and terrifyingly possible. Five stars. And yes, I double-checked my front door when I finished.

The First Thread by Nadija Mujagic
🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟
WOW, WOW, WOW!! This is a true deep and dark psychological thriller!
I’m floored by the intensity and pace of this book! There isn’t a dull moment and I couldn’t put the book down!
This story is based on real events that took place in the 80’s. That right there should instill some fear!

Agent Daisy Adams, is trying to find a little girl, Charlotte, who vanished from a kiddie pool in her front yard. As time goes on, and there aren’t any leads, she fears it might be too late…The intensity and panic are growing!
As Agent Adams searches old files containing records of other missing children she comes across several similarities and realizes that she’s most likely dealing with a serial killer.
As a reader, I enjoyed that there are different facets to this story, and it will be interesting to see in books 2 & 3 how parts continue to tie together.
This book is legit fantastic! I can’t believe how fast I flew through it with my jaw hanging open and gasping!

I was so lucky to be an alpha reader for this book! It’s not an easy read, knowing that a lot of this is a based on real incidents that happened, but it’s so well written and Nadija Mujagic knows how to create an amazing story!

**Book 1 comes out April 25!!**
A definite must read! Don’t miss this series!! Be on the lookout for books 2 and 3 to follow, which will complete this series!

Book 2- The Crimson Knot (coming in June)
Book 3- The Final Stitch (coming in August)

WOW! That was a wild ride and I need the next book immediately! Part of me is still soooo lost but the other part has an idea of what is happening. This book had my reactions clear all over my face, I was shocked, horrified, disgusted, and so much more. (Definitely check your triggers!) The fact that this is based on true events makes the emotions even harder to go through. However, Nadija has written this beautifully and these stories deserve to be told and brought to light. Nadija has outdone herself and I can’t wait to read the next one.

I am honored to be an ARC recipient of this book.
Comes out April 25th with 2 more in the series to follow!

⭐️⭐️⭐️⭐️💫 (4.5)

Based on true events. This book was wild, dark and twisted, but in a good way. I was constantly on the edge of my seat, not knowing what to expect next.

It gave me Criminal Minds meets Law and Order SVU vibes.

If you enjoy True Crime and Dark Thrillers. This is a must read. Plus this is book 1, in the 3 book series. I’m patiently waiting for book 2 to be available.

Be sure to add The First Thread to your TBR collection, available April 25th!!!!

Thank you Nadija Mujagic for giving me the opportunity to receive a ARC copy. I was so excited to of received this opportunity

Set in the 1980s, The First Thread follows rookie FBI agent and single mom Daisy Adams as she’s thrown into a chilling case that hits too close to home, the disappearance of a young girl from her front yard. As Daisy juggles her career and motherhood, she becomes deeply entangled in a nightmare rooted in true events. The deeper she digs, the darker things get. With emotional stakes and psychological tension running high, this story isn’t just about finding a child, it’s about confronting every parent’s worst fear. This is the first book in a gritty true crime thriller trilogy that dares to ask how far someone will go for the truth.

Okay, listen. I live for true crime, so when I found out this was inspired by real events? You know I dove in headfirst. The author was kind enough to give me a copy which did not affect this review. The First Thread did not disappoint. From the very first chapter, I was hooked. Like white-knuckling my Kindle and forgetting I had responsibilities kind of hooked. Sorry Hubby!

This book is pure adrenaline. The pacing is fast and tight, no meandering plot here. Every chapter ratchets up the tension until you’re fully in it, heart racing, palms sweaty, side-eyeing your front door like maybe you should double-check those locks. Again.

Daisy, our main character, is so raw and real. She’s not some untouchable superhero agent. She’s a tired mom running on caffeine and grit, trying to balance work stress with mom guilt while being tossed into the most terrifying case of her life. Her emotions? Totally believable. You feel her panic. Her exhaustion. That sick feeling when the case starts mirroring her own life? Yeah, it got to me.

The writing doesn’t try too hard, and that’s what makes it hit even harder. Nadija Mujagic lays it all out in a way that’s brutally effective, no fluff, just pure gut-punch after gut-punch. I actually had to pause at one point because I forgot to breathe.

And since this is based on true events, that creepy, lingering feeling? It sticks with you. There’s something about knowing this really happened, or could happen, that makes it so much more impactful.

Now let’s talk about that ending. I am absolutely dangling off this cliff, and I need book two now. Like yesterday. Someone check on me until it drops because Nadija left me hanging in the most torturous, amazing way possible.

This book had me pacing like I was the one solving the case. If you're into thrillers with emotional depth, psychological tension, and a story that feels way too possible, The First Thread is your next obsession. Nadija Mujagic doesn’t just tell a story, she throws you straight into it and leaves you breathless. This is the start of a series that promises to be unforgettable. Grab it, lock your doors, and clear your calendar. You're not putting this one down.

This is a fast-paced and intriguing start to the FBI Agent Daisy Adams series, with a strong premise and engaging investigative elements that kept me invested for most of the story. The author does a great job establishing tension and momentum, and I appreciated the overall atmosphere and character building.

The audiobook narration really elevates the experience. Matt Godfrey and Jennifer Pickens both deliver excellent performances, bringing energy and strong emotion to their characters. Their narration helped me stay immersed in the story and added depth to the characters, making this an enjoyable listen overall.

That said, while the book does include a disclaimer that it ends on a cliffhanger, the actual ending felt extremely abrupt. It stops quite literally in the middle of a conversation. I genuinely thought there had been a download error and went back to double-check, only to realize that this was indeed how the book ends. I don’t mind cliffhangers—when done well, they can be very effective—but I prefer them to end in a way that builds anticipation and excitement for the next installment. Unfortunately, this ending left me feeling more confused than compelled, and ultimately unsatisfied.

Even with that frustration, there’s a lot to like here, especially in terms of narration and the promising foundation of the series. I’m still curious about where the story goes next and can see potential for the following books to build on this start.

Thank you to Tantor Media and NetGalley for the ARC.

The First Thread by Nadija Mujagić
(Can I give it 10 stars??)

Okay. WOW. The First Thread was an absolute rollercoaster—and I didn’t want to get off. Nadija Mujagić has officially claimed a permanent spot on my “auto-buy” list. This book was phenomenal from start to finish, and let me just say… JESUS. The character, not the religious figure (although the vibes are amazing), completely stole the show. I couldn’t help but fall for him—sharp, complex, unforgettable.

The fact that this is based on true events? My brain is still trying to process that. It adds a whole new layer of depth and emotional gravity that lingers long after the last page. Nadija doesn’t just tell stories—she draws you right into them (it’s intentional), and you feel every twist, every surprise, every gut punch.

This is my third book by Nadija, and let me tell you—she has never missed. Not once. She writes with heart, fire, and a kind of authenticity that pulls you in and refuses to let go.

To Nadija: I need books two and three. Like... yesterday. I’m sitting here, watching the clock, imagining my life as a dramatic series of scenes set to elevator music until the next one drops. Hurry up, girl. My life depends on it.

If you haven’t read The First Thread, do yourself a favor and jump in. And while you’re at it, grab everything else she’s written too. You won’t regret it.

Highly, HIGHLY recommend.

The First Thread is an utterly gripping, emotionally devastating psychological thriller that left me breathless and haunted long after I turned the final page. Nadija Mujagic masterfully captures the panic, helplessness, and heartbreak of a parent’s worst nightmare - and wraps it in a tense, beautifully layered story that is impossible to put down.

Mujagic doesn’t just tell a story - she immerses you in it. The writing is razor-sharp, the atmosphere thick with dread, and every twist lands with a punch.

What really sets The First Thread apart is that it’s based on true events. That connection to real life adds a whole new level of depth and makes the story even more chilling. Mujagic sheds light on a dark chapter in American history and gives a voice to families who never got answers.

If you’re a fan of psychological thrillers that are as heart-wrenching as they are suspenseful, this book is a must-read.

In Nadija Mujagic’s chilling FBI thriller, The First Thread, we follow the investigation into the disappearance of six-year-old Charlotte, who vanishes from her front yard kiddie pool in the blink of an eye! Set in the 1980s and inspired by true events, it’s a haunting and unforgettably gripping look at a parent's worst fear.

Mujagic’s gradual build-up of dread is masterful. By alternating between the tense investigation of Agent Daisy Adams and unsettling prisoner perspectives, the story kept me reeled in until the final second!

The audio narration by Matt Godfrey and Jennifer Pickens is a MUST—it adds a layer of emotional clarity that makes the stakes feel incredibly personal. They are both very talented voice actors! 5/5 stars for this series opener, and I’m eager to hit play as soon as the next audio is released!

***I received an advanced audio narration via NetGalley. The opinions expressed are my own.***

Oh Lordy! This one cuts deep and talk about leaving us on a cliffhanger. This is a series I’ll be watching out for.

Smart, gruesome and graphic there was a point I was literally boaking at the description- do people know what boaking is? Heaving? Gagging! You get the picture. One of the more memorable detective type novels, a fairly short first instalment that delivered enough for me to become invested in Agent Adams’ career and the cases she works.

The content is harrowing and sinister of course, it covers missing children which is always difficult. It’s really difficult not to spoiler, I’ve gone back to the synopsis several times and I really don’t want to give anything away, but safe to say look out for this one on December 23rd.

I loved the narration too.

Huge thanks to Tantor Media and NetGalley for the opportunity to review this excellent ALC 🎧

I liked this short introduction to the missing child case. Even though we don't get the whole story, we get to meet the whole interesting cast of characters. The villains seemed pretty interesting and evil and I'd love to read the sequels.

I read the book in audio format and the readers were good. I give the entire reading experience 3.5 ⭐️. I didn't get a very accurate picture of how much time went in this first part of the book, but it didn't bother me much because I know that a sequels are coming. Hopefully the next parts will be released soon and I wish they will be a little longer.

Maybe this shorter "serial story" format will get more of our times impatient people, to pick up the book. Thanks to Tantor Media and NetGalley for the opportunity to read an early audio review copy of the book!

*I had access to an advance copy of this audiobook in return of an honest review*

This is the first book in the FBI Daisy Adams series, who is the main character. A single mother, she struggles with pressures of the job especially when her most recent job is about a young child who appears to have disappeared without a trace.

The audiobook has two narrators, one taking place in the past. Throughout the book, pieces start clicking into place before leaving the reader wanting more as the first thread concludes.

The story is pacy and grabs your interest immediately. The narrators are good and help create both drama and mystery. I am certainly intrigued to read the next book in this series!

I binged this audiobook in one sitting!! Right away, from the very first sentence, I knew I was hooked!

The multiple POVs and time jump back and forth from the 80s to current was done so well. I always loved each POV the most when I was in it but then I felt the same way when it switched! It was all so good!

Deeply dark, twisted and highly disturbing, but in a way you couldn’t turn away from! I’m thoroughly wrapped up and going to read the next two books ASAP! Fingers crossed the audiobooks for those will be available soon!

I loved the narrators They did phenomenal representing their characters and enhancing the suspense and creep factor.

"The First Thread" by Nadija Mujagic is a chilling start to a series inspired by true events. It dives deep into the darkest corners of human psychology and had me on edge the entire time. The tension builds slowly at first, then tightens like a noose with each chapter, pulling you deeper into the darkness. The characters are psychologically complex—flawed, layered, and disturbingly real. Twisted, intense, and impossible to put down—I’m hooked and can’t wait to see where the next two books take us.

The First Thread by Nadija Mujagic is the first book in a true crime thriller trilogy and is easily a 5 🌟 read! I received this as an ARC and I am very impatiently waiting for the second book! The First Thread is based on true events which means at times the subject matter is a little harder to get through for me personally. I typically don’t read or watch a lot of true crime so knowing these details are not just coming from the mind made this all the more chilling and haunting, but Nadija does a wonderful job of laying this story out. I genuinely can not wait to continue the series and read more from Nadija!!

This book completely pulled me in from the start. What stood out to me most was Agent Adams. She isn’t just another tough detective; she’s a mom, and her emotions bleed into every decision she makes. I really felt her fear and exhaustion, and it made me anxious right along with her.

The fact that it’s inspired by true events made it even more chilling. Some parts were hard to read because of the subject matter, but that’s also what made it so powerful.

If you like thrillers that really make you feel something, I’d absolutely recommend this series. I can’t wait to start the next one.

Knowing this story is based on true events makes it a tough pill to swallow. Kids are so innocent, born with curiosity, trust, dependent on adults to love them, teach them, and protect them. Monsters are very real in this world and pret on the innocent. This book is well written. Unfortunately I find Agent Adams to be dry, stuffy, and extremely reclusive. Her character gives me anxiety. I hope that changes in the next two books. I will certainly read this trilogy all the way through.

Good start to a series.

This is the start of a series. It involves FBI agent Daisy Adams, and her daughter Lila, whom she’s trying to protect from all the horrible things she sees happening to other children and people in the world. And boy do we hear about some of those people I am going to read book 2.

Thousands of children go missing and Agent Daisy Adams has just been put on the case of missing 6 year old Charlotte Mercer. The case is a mystery with no witnesses and no clues. As Daisy digs further, she can't help but think of her own daughter and what she would be if Lila ever went missing. The First Thread dives into the chilling monsters in plain sight and the parents living their worst fears.

This is the first book in a trilogy and I am looking forward to continuing the story. The author was inspired by the true events of missing children in the 1980s and used that to take you on an intense and gripping ride. It was dark and twisted in a good way and leaves you on a cliffhanger, eager for the next book. Personally, I don't always love a FBI/Police MC read and also don't do many series, but I was totally on board for this one and will be watching for book 2!

Wowwwww...... Talk about a jaw dropping, chest grabbing, holding breathes I didn't know I was holding story. Let me tell you, this ain't no Scooby Doo mystery. I'm shook after reading this. This story had me feeling emotions that I didn't think I'd ever feel. The fact that it is based on true events sent me down a rabbit hole. The story was quick and writing style sharp. Nadija was on point putting this story together. Once you open the book you won't want to close it. I'm still sitting here trying to wrap my head around what I've just read. Can't wait for book 2.

Drawing inspiration from harrowing real events, THE FIRST THREAD by Nadija Mujagic unfolds as a gripping psychological thriller and marks the inaugural entry in the FBI Agent Daisy Adams series.

Set against the haunting backdrop of the 1980s, this novel immerses readers in the unsettling mystery surrounding the disappearance of a six-year-old girl. As rookie FBI agent Daisy Adams delves into the case, she is not only driven by her professional duty but also beset by her own personal anxieties regarding the safety of her daughter.

This powerful narrative intertwines the professional and the deeply personal, creating a tension that keeps readers on edge. With its masterful storytelling and intricate plot twists, THE FIRST THREAD promises to be the first thrilling chapter in an exciting trilogy, leaving audiences eager for the next heart-pounding installment.

About...

Six-year-old Charlotte Mercer disappears from her front yard in Silver Spring, Maryland, with no witnesses and no clues.

Rookie FBI Agent Daisy Adams is called to the case, which quickly becomes a haunting investigation. As Daisy races against time to find Charlotte, she begins to see similarities to other missing children's cold cases and suspects a serial killer is involved. The case shatters her personal control as a single mother, forcing her to confront the creeping fear that her own daughter, Lila, could just as easily disappear one day.

My thoughts...

THE FIRST THREAD delves deep into the visceral fear and terror associated with the unknown, exploring the psychological and emotional toll that investigative work takes on agents who are also parents. The narrative underscores the theme of "monsters hiding in plain sight," presenting a chilling examination of how danger often lurks where least expected.

At the heart of the story is Daisy, a remarkably relatable FBI agent and a devoted single mother. Her character is crafted with depth, embodying the internal conflict between her professional duties and her maternal instincts. As she grapples with the harrowing realities of her job, Daisy's worries for her daughter, Lila, amplify the emotional intensity of the plot, drawing readers in with a rich tapestry of love, fear, and resilience.

Haunting and chilling, the book culminates in a suspenseful cliffhanger that leaves readers craving more, setting the stage for the subsequent novels in the series. The Crimson Knot: An FBI Agent Daisy Adams Thriller (Book #2 -audio Feb 17, 2026) and The Final Stitch: An FBI Agent Daisy Adams Thriller (Book #3- audio Mar 03, 2026) promises to unravel the complexities of Daisy's world, intertwining personal and professional challenges in gripping adventures that will keep readers on the edge of their seats.

My first by the author, and I look forward to more!

The audiobook...

The audiobook is a mesmerizing experience, brought to life by the talented duo of Matt Godfrey and Jennifer Pickens. Their dynamic narration infused each character with vivid personality, weaving an enchanting tapestry of voice that perfectly captured the rich setting, deep emotions, and palpable suspense. Every word they spoke resonated with intensity, drawing listeners into the heart of the story and making it impossible to turn away.

Recs...

If you enjoyed the fast-paced, 1980s-set investigation and the high-stakes perspective of a mother in law enforcement found in The First Thread, you will enjoy books by authors who share similar themes, such as Jessica Knoll, Robin Mahle, Jess Lourey, Jennifer Hillier, and Willow Rose.

A special thank you to Tantor Audio and NetGalley for sharing an advanced listening copy in exchange for my honest thoughts.

There’s no forgetting what it felt like to grow up in the 1980s with the faces of missing children printed on milk cartons. For many of us, those cartons weren’t warnings; they were grim wallpaper. Adam Walsh, Lee Standifer, Johnny Gosch—to name only a few. The Jeanine Nicarico case in Illinois always haunted me. Countless others. The stories didn’t end; they just faded into static. So when a thriller like The First Thread dares to take that generational wound and drag it back into the light, I pay attention. Nadija Mujagic isn’t just writing a mystery. She’s resurrecting a fear many of us grew up with but never had the words to name. Before terms like “stalker” even existed in the public consciousness.

I don’t need another procedural. I need a story that remembers. That knows what it felt like to be young, walking past posters stapled to telephone poles, wondering why grown-ups whispered in grocery store aisles. Daisy Adams isn’t chasing a case. She’s chasing a ghost that looks too much like her daughter. That’s the horror Mujagic understands. It’s not the crime scene that ruins you. It’s the silence. The empty bedrooms. The way a child’s photo becomes evidence. Daisy doesn’t collapse into cliché. She holds it together the way mothers do, because they have no other choice. Back then, the worst four words a parent could hear were: your child is missing.

You want to know what failure looks like? Read this book. The First Thread isn’t just about a missing girl. It’s about what happens when the search stops mattering. When the cops stall. When the media moves on. When people start looking at the mother like she’s the problem. Mujagic doesn’t flinch. She writes the investigation the way it actually unfolds: slow, scattered, humiliating. No heroic breakthroughs. Just doors that stay closed. I grew up in Illinois. I’ve seen exactly this kind of case disappear into paperwork. So, when Daisy starts losing her grip, it’s not dramatic. It’s inevitable. This book understands how it happens. That’s what makes it terrifying.

The setting only sharpens that unease. Mujagic captures D.C. with a kind of haunted specificity. When I think of that city, I don’t just think of Capitol Hill. I think of Rock Creek Park. I think of Chandra Levy. I think of cases that exploded in the reactive mass media, only to vanish into silence. The First Thread carries that same ache. It’s about the stories we stop telling.

This is book one in a trilogy, and Mujagic resists the urge to offer easy closure. The ending doesn’t come with a bow; it comes with a knot. And for me, that’s exactly how it should be. Real pain doesn’t resolve itself in one arc. Real trauma doesn’t end in a courtroom.

The First Thread is a hell of a start. It doesn’t just echo the tragedies of the past. It demands we listen. It stares into the cold machinery of justice and asks how many kids it has failed. This isn’t just a harrowing story. It’s a reckoning.

Fun fact, I'm old, and can tell you that the 80s were indeed rampant with child abductions. They were not all subtle abductions either; some were bold and would try to nab kids from their school playground during recess. We didn't have fenced-in playgrounds back then. I know the 80s were rough on kids because I was nearly one of those kids and still remember those events. So, this book hits me at a different level. A story that is based on real events, though I am not 100% sure which case studies this book is inspired by, specifically.

This book follows Daisy Adams, an FBI agent assigned to solve the missing person's case of 6-year-old Charlotte. As Daisy delves deeper into this case and others like it, we see how this affects her personally. I can't imagine being someone assigned to anything that causes harm to kids; just seeing hurt kids in the medical field is hard enough. Seeing it in law enforcement, I can imagine it taking its toll. This book (possibly the whole trilogy) kind of deals with the psychological effects that this has on Daisy and the relationship she has with her own daughter. Alongside the investigation of the missing person, we see several other scenes, including what we presume is the childhood of a serial killer, the incarceration of that same man in the 2000s via his cellmate Jesus, and the emotional and psychological effects of a missing child on a parent.

This is a fast read, and tough at parts because there is mention of harming a child, attempted rape, and the slaughter of animals. The story maintains a steady pace and is an emotionally charged journey. The fact that this is inspired by real events lends the book a sense of doom, as the events that occur in the book are indeed real-life occurrences. If you enjoy true crime or psychological thrillers, this is worth a try.

The narrators of the audiobooks do a fantastic job. Pickens does best in these police and serious type dramas. I will say that Godfrey steals the show, especially when we get into the jail scenes, bringing that complete insanity to his murderers, making the story all the more intense. Love the varying undercurrents.

Don't expect to have any resolution in this book; the blurb is quite clear that this ends on a cliffhanger as we continue on the journey of this dark trilogy.

The First Thread by Nadija Mujacic is dark. Like creepy, unsettling, made-me-squirm dark. This is the first book in a planned trilogy, and yes, it absolutely ends on a cliffhanger, so go in prepared if you are someone who needs closure.

The story alternates between rookie FBI agent Daisy Adams, who is investigating the disappearance of six-year-old Charlotte Mercer from her front yard in 1980s Maryland, and the unsettling perspective of an unknown but deeply disturbed perpetrator, slowly weaving together the psychological threads that lead to violence. As the case exposes a terrifying pattern of missing children, Daisy is forced to confront both the growing threat in her community and her own fears about protecting her daughter.

If you like true crime or dark thrillers, this one is going to work for you. Some of the chapters from the perpetrator’s point of view genuinely made me uncomfortable, not because of graphic violence, but because of the creepy details like harm to animals and a truly messed-up upbringing. As the perpetrator's part of the story begins to uncover, the tension builds in quiet, disturbing ways that are far more unsettling than outright graphic details.

I also loved that this was short. I listened to the audiobook in one afternoon, which felt perfect for this kind of story. The dual narrators were fantastic and fully embodied both characters in such a believable way. All the emotion, the tension, and the creepiness really landed.

About halfway through, I knew I was not going to be patient with a cliffhanger ending. I looked up the rest of the series and found out the audiobooks for books two and three are not out yet, but the ebooks are available on Kindle Unlimited. I downloaded both immediately and will be starting book two ASAP. Even though I would much rather listen to those narrators again. Maybe I will try to be patient. But honestly, I doubt it.

This one really worked for me. Dark, fast, and tense in the best way if that is your thing.

Thank you to NetGalley and Tantor Media for the advance copy of this audiobook in exchange for an honest review. All opinions are my own.

This is the first book I have read by this author, and I was amazed at how fast-paced and attention grabbing this book was. I was hooked by the first page and I'm left craving for more. Agent Adams really stood out as a character . She isn’t just another tough detective; she’s a mom, and her emotions bleed into every decision she makes. I really felt her fear and exhaustion, and it made me anxious right along with her. This book follows Daisy Adams, an FBI agent assigned to solve the missing person’s case of 6-year-old Charlotte. As Daisy delves deeper into this case and others like it, we see how this affects her personally. I can’t imagine being someone assigned to anything that causes harm to kids; just seeing hurt kids in the medical field is hard enough. Seeing it in law enforcement, I can imagine it taking its toll. This book (possibly the whole trilogy) kind of deals with the psychological effects that this has on Daisy and the relationship she has with her own daughter. Alongside the investigation of the missing person, we see several other scenes, including what we presume is the childhood of a serial killer, the incarceration of that same man in the 2000s via his cellmate Jesus, and the emotional and psychological effects of a missing child on a parent. This is a fast read, and tough at parts because there is mention of harming a child, attempted rape, and the slaughter of animals. The story maintains a steady pace and is an emotionally charged journey. The fact that this is inspired by real events lends the book a sense of doom, as the events that occur in the book are indeed real-life occurrences. If you enjoy true crime or psychological thrillers, this is worth a try. The fact that it’s inspired by true events made it even more chilling. Some parts were hard to read because of the subject matter, but that’s also what made it so powerful. Many thanks to the author, publisher and Netgalley.

This is an incredibly captivating thriller that pulled me in from the very first page and didn’t let go. Nadija Mujagic’s writing is sharp, intelligent, and emotionally charged, making the book impossible to put down.

Set in the 1980s - America’s worst time for missing children - this story follows Agent Daisy Adams as she attempts to locate a missing girl, Charlotte, who vanished without a trace from her front yard in Silver Spring Maryland one afternoon while her father fell asleep on the couch inside. With no witnesses, no clues, and not enough time, Daisy is worried this case may not have a happy ending. As Daisy races to find Charlotte, she is constantly battling the fear that her daughter Lila could one day be the next missing child she is trying desperately to locate.

The plot is a brilliant blend of suspense and psychological depth, with twists that are both surprising and satisfying. The characters are well-developed and complex, with their own unique motivations and secrets. The way Mujagic explores their inner turmoil, especially the main character’s, and their relationships adds an extra depth to the already intense narrative. I found myself rooting for some while questioning the motives of others, which kept me on the edge throughout the entire book.

The story unfolds with masterful pacing and is told through multiple POVs, creating a gripping, tense, and oftentimes chilling atmosphere. If you are a fan of thrillers with intricate plotting and unforgettable characters, The First Thread is a must-read. This is the kind of book that will stay with you long after you’ve finished it, especially since it is based on true events. I am impatiently waiting to read the next book in this series because I just have to know where this is headed. I highly recommend this for all thriller and true crime fans!!
