The Mother-in-Law
"I’m stuck in this house until my husband returns from his trip, and I’m going to have to figure out how to live with this woman in this dark and cold place. I fear that deep down, she might be quietly unhinged and harboring a dark secret."
Newlyweds Jess and Mark have it all… except a place to call their own. Moving into Mark’s family home feels like the right step, a temporary solution until they can buy a place. But what should be a cozy interim quickly unravels into something far darker.
The house, a looming Gothic relic, gives Jess the chills from the start, but it’s Mark’s mother, Catherine, who truly unnerves her. On the surface, Catherine is polite, even doting, but soon after Mark leaves for a business trip abroad, Jess finds herself alone with a woman whose kindness edges dangerously close to obsession. Catherine’s constant intrusions grow bolder, her presence more inescapable, until Jess is on edge in her own bedroom, unable to escape the suffocating watchfulness.
When Jess uncovers a hidden stack of letters, her world tilts. The letters, written by a woman claiming to be Mark’s real mother, shatter everything Jess thought she knew about the family she’s married into. Who, exactly, is Catherine? And what will she do to keep her secret buried?
This gripping psychological thriller is perfect for fans of Freida McFadden, Kiersten Modglin, and Daniel Hurst. Meeting the in-laws has never been so dangerous….

I thoroughly enjoyed and devoured this short, thrilling and suspenseful story! 🌟 It’s my first time reading a book from this author but it certainly won’t be the last. I’m really glad I came across them.
The Mother-in-law follows married couple Jess & Mark who move in to Catherine’s house (Marks Mom, Jess’ mother-in-law) in order to save money to purchase their own home. Shortly after their arrival, Mark finds out he has to fly out to Japan for several weeks for work, leaving Jess all alone in the creepy house with Catherine. Things get progressively worse until a fight for survival begins.
This story was fast paced, edge of your seat and just so engrossing. The chapters were super short which I love. The total book length is 224 pages which is great for me as I love a shorter read. Most people could certainly bash this out in one sitting/ one day.
I thoroughly recommend this book to anybody wanting a quick and easy to follow thriller book! 5 stars 🌟

This book was:
- a nail biter
- a page turner
- filled with terror
- frightening
- a quick read
It also had a pretty good story arc and great twists and turns. The subject matter was pretty dark. I didn’t expect it to go down some of the roads it did. Overall, I enjoyed it very much and would read other books by this author and recommend this book to readers who are looking for something on the more psycho side.

While this had so much potential, it felt rushed in places and fell short.

Wow! This book did suck me in from the beginning. There is evil and then there is mother-in-law evil😂😂😂 I recommend this book!
January 21, 2025
This is definitely the mother-in-law from hell. Actually it might be worse than that if possible. There is definitely something wrong with her and Jessica finds that out early in the book. It is not only a page-turner but also every chapter has you sitting on the edge of your seat. Great read..

2.5 rounded down -
i didn't care for this at all.. we didn't get much of an explanation or resolution and the characters were very annoying - the husband used "baby" and "vibe" in the same sentence MULTIPLE times...

Absurd
What a ridiculous novel. I actually liked the start of the book right until the climax; then it just became a cliched storyline we’ve all read before. I got so bored I started skipping pages to get to the end.

As soon as I saw this author had a new book coming, I messaged a friend, and we anxiously awaited its release date. I inhaled this one in record time!
Jess and Mark are newlyweds who make the tough decision to temporarily move into Mark's childhood home with his mother so they can save money for a home. Jess has some reservations, especially when she sees it's a huge Gothic mansion with a faintly sinister vibe. But her mother-in-law Catherine quickly puts her at ease, and Jess finds herself relaxing. However, Mark gets the news that he's up for a huge promotion, but there's one catch--he'll have the leave the country for about six weeks.
With Mark gone, Catherine begins acting strangely, treating Jess as if she's a child; scolding her, demanding to know her whereabouts, even walking in on her while she's undressing. Despite her efforts, Jess can't get the woman to understand boundaries. But when Catherine leaves for a short retreat with a friend, Jess gets the chance to explore the house, and she finds something that will change everything about Catherine...and her husband Mark.
This was an absolute thrill ride from start to finish! It was creepy, intense, and I couldn't believe the secret Catherine was hiding. Highly recommended! This book is available now on KU and paperback.

Definitely a Nail Biter
This book will have you on the edge of your seat. The story starts out innocently enough. Newlyweds Mark and Jess want to save money to purchase their own home so they move into Mark’s childhood home where his mother, Catherine, lives alone. His father, a prestigious judge, died when Mark was just a child. His only memory of him is he was extremely strict. Catherine is extremely doting on the couple, something independent/private Jess is not used to or comfortable with. Catherine changes when Mark leaves for an extended meeting in Japan. That’s when the scary and creepy stuff begins. I found myself rooting for Jess and then sympathy for a small boy named Clay who was stuck in the same room as Jess years before. It was easy to overlook how a woman in her 60s could have moved a drugged, 135 pound or so woman, but I guess it is possible. The story is definitely a page-turner and I will read another novel by this author.Technical error = on pages 6 & 88 Mark is said to work for an insurance company whereas on page 53 it says an advertising firm. I thought the characters were well-developed and believable, although the mother was creepy as hell. As I said before, it kept me on the edge of my seat but the ending was a too little “happily ever after.” I thought for sure Mark would be in on it and frankly, was a little disappointed to find out he was a nice guy. Thought it would be more fun if he wasn’t.

Newlyweds Jess and Mark decide to temporarily move into Mark's family home until they can buy a place. The house gives Jess the chills from the start, but it is Mark's mother, Catherine, who truly unnerves her. Catherine's constant intrusions grow bolder, and her presence becomes more inescapable. When Jess uncovers a hidden stack of letters, her world is shattered. The letters, written by a woman claiming to be Mark's real mother, upend everything. Who, exactly, is Catherine? And what will she do to keep her secret buried?
MOTHER-IN-LAW is a twisty psychological thriller about a woman's struggle against her unhinged mother-in-law. Picture this: your husband's away on business for a month, and you're stuck at home with your mother-in-law, who has zero boundaries. Doesn't sound fun, huh? Jess possessed a likable personality, coupled with keen instincts and a strong will to survive. As for Catherine, she's a definite monster-in-law. But she does bake a mean casserole and pie. 🤣
As the plot unfolded, Catherine's erratic behavior became increasingly noticeable. She was very protective of her secrets and would go to great lengths to keep them from her son. I felt great sympathy for Jess, and I was frustrated by the crazy situation she found herself in. Unfortunately, I can't reveal too much of the story, but I will say the plot twists were satisfying, and the ending wrapped up nicely.

I love when a book is tied up in a perfect bow at the end, this is not that book. While the story engaged me from the beginning- once we got to the climax, it slowly abruptly fizzled out. I needed to know more about Catherine, Nicholas and also Mark. There was so much left undone that this book felt Incomplete to me.
We start out getting to know mark and Jessica. They are newly married and are moving in with marks mother ( who has lived alone since his dad died ) to save up for a house of their own. Jessica comes off as introverted and shy, while Catherine ( marks mom ) is an overly affectionate woman. Immediately you sense tension. Shortly after mark has to leave for a business trip leaving Jessica and Catherine to get to know one another on a deeper level. This is when things take a very dark path… ending in death.

A newly wed couple make the decision to stay at the husband’s mother’s home. The husband has to leave for an unexpected business trip (gasp!) leaving the wife to stay at home with this mother. That’s where things start to get interesting and soon, sh!t hits the fan! It was a good read, no major twists or turns but still held my interest. The best way to describe this is that this is a story straight out of a lifetime movie - predictable, some mystery, a little drama and a happy ending. The end.

I chose this book because I have a wicked mother-in-law haven’t seen her in 15 years thankfully
I visualized myself being trapped in that house with her . Because she’s a cold hearted person . Thank goodness my husband chose me over her and we live a happy life
Thank God for Clay and his notebooks otherwise Jess would never have gotten out
Of there
I read it straight through. Couldn’t put it down
You never know what evil lies behind the surface of some people

Fantastic!! Kept me gripped from start to finish with twists I didn’t see coming. The conclusion, in my opinion, sets up a great opportunity for a sequel or prequel.
What’s even more interesting to me is how this plot line isn’t really out of the realm of possibility. If I didn’t love my mother-in-law I’d be giving her the side eye, for sure!

Wow! Jessica and her husband Mark ask Catherine to take his wife in while he goes to Japan for six months for his insurance job training.Also well at first, Jess finds her a bit strange, then all things go astray. Fast paced, well written and characters that will scare you.A great , interesting drama. Twists!

Hmmmm …. I loved the suspense through the whole book and kept reading more but I felt disappointed reading the ending …. It was too perfect. Not a bad read but I just wanted a little more at the end.
January 19, 2025
The book was ok but I found it a little predictable. The storyline was similar to a dozen different horror movies. Parts of it were exciting but the ending was a let down for me. Not all stories need a happily ever after and in this case I think it ruined the story.
March 1, 2025
Creepy and suspenseful from the start, a real page turner of a story. A mother in law without boundaries, and over sensitive behavior leads to unraveling secrets and extreme behaviors. Twisted and well put together. Doesn’t disappoint with surprising conclusions.

Crazy, good story!!!
I was expecting a strange and weird twist, but certainly NOT what happened in this story! The feelings and emotions send you reeling. You are compelled to finish the story. Highly recommend!

the start was a bit boring / slow for me so it took me a long time to finish the book. middle part was when I got hooked. loved the twist but kinda hoping for something dark & another twist at the end 😂 the ending was too happy for a thriller/horror book

The book was a bit of a slow start but grips you with an early twist. There are many chapters that I skimmed because it didn’t seem to progress the story very quickly. I loved the end and how the story resolved. It was a good experience overall!
April 21, 2025
A quick read but I found myself skipping paragraphs and then pages to get to the end. The premise was OK. The story dragged and became predictable. Not a lot of depth the character and it all wrapped up too neatly in the end. Missed opportunity to dive deeper into Paul, Steven or Mark’s stories.
April 26, 2025
Scary!
I found this book to be terrifying in certain situations. I can't imagine anyone going through this in real life. Couldn't wait till the end, but refused to jump forward, didn't want to miss any of it. Excellent writing!

Not that many twists in this story, predictable ending, was expecting a twist at the end
This book was ok, but it lacked suspense for me and the ending was a predictable, happy ending. I prefer more twists and turns ….

Definitely a fast paced read that got me out of a reading slump! It started a little slow but once it picked up I could not put it down! Probably not the most thought provoking plot but it gets 5 stars from me for entertainment value alone.
