The Monster Next Door
Monsters don’t always break in. Sometimes, they’re invited . . .
Maddie likes her life orderly. She manages and lives in the block of flats her father owns. Control is how she keeps anxiety at bay. Then, elderly Greta moves in.
Greta is quiet, precise, frail, and unsettlingly observant. When Maddie mentions her studies and desire to be a writer, Greta offers something her story. A past shaped by survival in a concentration camp. The kind of story that demands to be heard.
Soon, Maddie becomes the keeper of Greta’s history. At the same time, small things start to happen in the building. Objects move. Residents are unsettled. And Ross, Maddie’s ex, turns up again. But Greta knows exactly how this story goes.
What to tell. What to leave out. And how to draw Maddie in.
As Greta’s wartime accounts grow more disturbing, Maddie begins to realise she isn’t just being confided in. She’s being asked to rewrite a very dark past . . .

Wanted to DNF but I thought this story would go SOMEWHERE. Disappointing. The only reason it’s getting two stars is Reil’s use of language.

Trust Was the Real Monster
ARC Review: Thank you to the author/publisher for the advance copy. All opinions are my own, including the unhinged ones. I received a free copy of this book via Booksprout and am voluntarily leaving a review.
This thriller masterfully treads the line between subtle manipulation and creeping dread, proving that chaos isn't always necessary to create intense tension. It builds dread through manipulation, emotional vulnerability, and that constant feeling that something is deeply off. The paranoia creeps in slowly, but once it does, it doesn’t let go. And honestly, I was all in.
At the center is Maddie, a woman whose compulsive need for routine makes her both compelling and vulnerable. She clings to order as protection against her anxiety, convinced that if she keeps everything in its place, her world will stay manageable. Then Greta enters—the fragile, elderly woman haunted by her wartime past, seemingly offering Maddie a purpose: the task of preserving a painful, personal story. But from the moment they meet, something feels terribly wrong. Their dynamic is magnetic in the worst way—Maddie seeking meaning, Greta quietly taking control—and that imbalance turns every conversation into a battlefield.
The strongest thing about this book is that it weaponizes emotional vulnerability; it weaponizes storytelling itself. What begins as an act of remembrance twists into something darker, making every confession feel like bait, every bond suspicious. The tension isn’t built on violence but on emotional control, subtle manipulation, and the fear of realizing too late that someone has been steering the narrative all along. Each interaction feels loaded, every moment a carefully set trap. The psychological conflict felt sharp because the manipulation was so believable. Watching the power dynamics tighten little by little is both chilling and brilliant; it’s a reminder that fear is even more daunting when cloaked in kindness, and it leans into that beautifully.
The atmosphere is another standout. The apartment setting creates an oppressive, claustrophobic vibe where even mundane moments become ominous. The pervasive sense of unease seeps into ordinary moments, which makes everything feel more intimate and more threatening. It creates the kind of paranoia where even harmless details feel sinister. That quiet dread was chef’s kiss!
The character work also deserves credit because the emotional stakes felt real. The vulnerabilities that drive their actions feel genuine, rooted in need rather than plot devices. This emotional realism makes the manipulation all the more impactful. The dual perspectives and unreliable perceptions keep doubt alive; no one is completely trustworthy—not Maddie, not Greta, not even the narrative itself.
The layered reveals fit seamlessly into the psychological tension, landing with emotional weight. Even when I anticipated certain twists, their execution still resonated, because the emotional fallout mattered just as much as the surprise. The difference between a flashy twist and a truly effective one is clear here: satisfying, earned, and deeply felt. I only wish the final twists packed a slightly more devastating punch—that extra hit of emotional impact.
Pacing is spot-on. This is a slow burn that never lags—each chapter intensifies suspicion, each reveal ratchets up tension. By the end, I trusted no one—which, for a thriller, is exactly what I want 😅.
The writing is immersive and controlled, and that restraint is what makes the suspense work so well. Instead of overt drama, the story builds suspense naturally through discomfort and uncertainty. That steady pressure intensifies the dread and makes the suspense feel earned. The whispering tension, instead of loud shocks, makes the story even more unsettling.
If you love psychological thrillers filled with mind games, creeping paranoia, and slow-building dread, this book delivers in spades. It’s perfect for readers who prefer manipulation to mayhem and love stories that dig deep into motives, second-guessing, and losing grip on truth. If your favorite thrillers make you question motives and doubt everyone’s sincerity, this will become your obsession.
This novel understands that true horror isn’t violence—it’s trust placed in the wrong hands. What makes this book work is how quietly cruel it feels. It took ordinary vulnerability and turned it into something dangerous. It’s a story that wraps you in psychological control so subtly that you don’t realize how deeply you’re involved until you’re spiraling. That kind of psychological control is hard to pull off, and this book did it with confidence. Even if I wanted the ending to be a touch more impactful, I’d still wholeheartedly recommend it because what it does well, it does really well: atmosphere, tension, emotional manipulation, and slow-burning psychological suspense that keeps tightening until you can’t look away. And honestly? Any book that makes me distrust every act of kindness deserves my respect. 👏🏾
Overall, the story delivers classic psychological suspense—lingering unease after the final page. It satisfies without overexplaining, twists without betraying itself, and leaves behind that deliciously unnerving realization that the most dangerous monsters rarely look like monsters at all.
The Monster Next Door is psychological entrapment disguised as intimacy—smart, sinister, and terrifyingly quiet. It doesn’t demand your attention loudly; it takes control softly—and once it does, you may never trust your story again.

Okay, this book? Deeply unsettling … this is one of those psychological thrillers where you *know* something is off almost immediately, but the deeper the story goes, the more twisted and morally messy it becomes. I had suspicions early on, but I absolutely did not expect how far it would all unravel.
Maddie lives in and manages the apartment building her father owns, and from the beginning, you can feel how seriously she takes her role as the building’s unofficial “keeper.” She checks on the tenants, keeps things orderly, and clings tightly to routine because control is how she manages her anxiety. At first, her attention toward the residents feels responsible, almost comforting, like she genuinely sees it as her duty to look after everyone in the building.
Then Greta moves in … Greta is elderly, quiet, observant, and somehow immediately unsettling. When Maddie mentions her studies and dream of becoming a writer, Greta offers her something irresistible: her story. A past shaped by surviving a concentration camp. The kind of story that feels important enough that you *have* to listen. As Maddie becomes the keeper of Greta’s history, strange things begin happening around the building. Residents grow uneasy. Objects move. Her ex starts reappearing at exactly the wrong moments. And through it all, Greta always seems one step ahead, like she already knows how everyone’s story ends.
The psychological manipulation in this book was honestly top tier. Greta is one of those characters who seems fragile and harmless until you realize she’s quietly controlling the emotional temperature of every room she enters. The entire book had me second-guessing everyone, including myself as a reader. There are definitely heavier themes throughout involving racism and anti-Semitism, but nothing comes across as graphic or unnecessarily offensive. It’s meant to create discomfort and highlight how fear, prejudice, and vulnerability can be manipulated, and it does that *very* effectively.
And the ending? Whew. By the time you get there, you’re no longer asking *what* happened — you’re asking who the real victim actually is. That’s the kind of ending I love: the kind that leaves you staring at the wall for a minute afterward, reconsidering the entire story.
If you like slow-burn psychological thrillers with unreliable dynamics, creeping dread, morally gray characters, and manipulation so subtle you barely notice it until you’re fully trapped in it too, absolutely pick this up.

This was so good! I was gripping my iPad the entire time. This was so intriguing, so intense. I didn’t expect this to be dark, but it was. I couldn’t put this down once I picked it up. Listening to Greta’s part was so thrilling. I wanted to know more. And when Maddie started to realize it was so much more…i was holding my breath at some points. This really grabs you and pulls you in. The depth of this was amazing. Very well written. I can’t wait to read more from this author.

Not your typical thriller. This one is quite dark and takes you along for the ride right along with the main character. It's a story that delves into the power of manipulation and twisted narratives and how the most unassuming people can be the most dangerous. TW for Anti Semitism.

This was....intense
I had a difficult time with this book: on one hand it was strangely compelling, and on the other it was appalling. I didn't want to finish but I had to finish...very uncomfortable read.

Just could not get into this book, it was slow and boring, it was almost a DNF but skimped the last few chapters to see if the twist at the end was worth it. It wasn't.
