Single Mom's Undoing

Lucky Lady Reverse Harem #24

by Kai Lesy

"What the hell are you doing here?"
My voice cuts through the mountains like a blade.

Three shadows from my past stand on my doorstep—my brother's best friends.
Battle-hardened Navy SEAL silver foxes. And one of them is about to discover he's a father.

I came back to Blackthorn Falls for one the trust fund that could save my son's life.
Get the money. Stay invisible.
And get out.
But these men make hiding impossible.

Three powerful men circling a broken woman, peeling away every wall I've built.
But secrets have consequences.

Someone's been watching. Waiting. And now that I'm back...
The danger I ran from five years ago is closing in.

Their protection feels like possession.
Their love for my little boy breaks me completely.

And the most terrifying part?
I don't want to run anymore... even if staying costs us everything.

Laced and Ready to Run

There are some plot holes and discrepancies, but that doesn't stop this from grabbing my attention and holding on with both hands. I truly had a hard time putting it down to take care of life matters.

Even when Clara Barnes drives me batty, I still can't put it down. Of course, it's possible that Jace Wilder, Carter Lockwood, and Damon Cross have something to do with that. Maybe. Perhaps. 😘

Maybe this was meant to happen. Maybe this will be my reckoning.
-- Clara Barnes

Intimacy was nearly weaponized a couple of times or those moments didn't naturally fit, but each scene was incredibly hot. Desks are cleared, doors used for leverage, and more. I will admit to phantom pains from the DVP, though. 🍆🍆🌮 Yeah, that one gets me every time.

There's also plenty of dark matter to contend with from kidnapping to bribery to murder. The suspense is there (another thing that kept me reading like it did) and gets a little woo-woo at one point, but it makes for interesting drama.

This is the first book in a long while from Kai that I've picked up. I look forward to the next time.

H1-3 = late 20s, early 30s?; h = 25 (stated age even though 23 fits the timeline better)

There are secrets upon secrets in this book, along with some juicy surprises. Nothing good has ever come (in books) when the FMC keeps so many secrets. This story was involved and gripping and with a lot of action, as well. I liked this story. At times, it was frustrating, however, when bad decisions are being made. Parts were heartwarming, somewhat angsty and emotional. My overall impression was that this was a good read. I kept turning the pages to find out what happens next. I would definitely recommend this novel.

[Katherine · Rating 3 out of 5]

This story was just ok. Some parts of the story felt rushed and other parts didn't really feel fully formed.

[Taara Amrine · Rating 5 out of 5]

Life can be super hectic. Having to make hard decisions under duress doesn't help. This story covers it all from murder and kidnapping to children and hope. Add in a lot of hot love scenes and this is a love story to wish for.

I can say I love this author and this book is no exception. I couldn’t get enough of the story and the dynamic. This will be added to my re read selection. I can’t wait to see what she comes out with next.

did we read the same thing?

Those reviews must be fake because that was so repetitive and boring.

I couldn’t get past the fact that they all waited so long to get Matty the surgery. I thought he was your world, why not push past it all and ask for help to get it right away. 🤦🏻‍♀️

Wasn’t great.. predictable and not spicy at all

Clara has no choice but to go back home; she needs to get access to her trust fund to help with her son Matty's life-saving surgery. She's not been back since her brother died, but she needs to stay under the radar for two reasons.

Carter, Damon, and Jace were Stephen's best friends, and they were attracted to Clara. Carter, in particular, since he just started a relationship with her before she left suddenly. When they find out she is back, they soon find themselves at her door. This time, she is not getting away from them.

Clara knows that she is treading a fine line, getting involved with all three men. They may want her to stay, but she can't; her life depends on it. She can't take the chance of them finding out why she suddenly left, as well as finding out about Matty.

The four soon deal with all the fallout the relationship brings to the table. Damon's ex is back on the scene, wanting access to their daughter, Shiloh. Carter is concerned about his sister and the downward spiral she is on. He wants nothing to do with his father's company because he knows that Bill Lockwood's true colours are hidden behind payouts, back-room dealings, and shadier connections. What they don't know is that Clara is back in the crosshairs of this man, and he will make sure he comes away with what he wants.

Will Clara ever be free of the pain, guilt, and terror that have surrounded her since her brother's death? Will she ever get justice for him? And will she ever get her happily ever after with the three men who have loved her for a long time?.

[Knight Linda · Rating 5 out of 5]

A powerful story of secrets and suspense that captures your interest from the very beginning, and it was so well written that you zum through reading it not realizing you was at the end. Clara returned to her hometown in hopes of sneaking in and out before anyone knew she was back. That went by the way side when her brother's attorney was out of town on an extended holiday giving her brother's three bestfriends time to learn she was back. They had questions, and they were not leaving her alone, until they had answered if then. Carter, Jace, and Damon were not only all in love with her. They were all alpha males swearing that they would protect her. They might have had better luck protecting her if she would have been honest with them, but she absolutely refused to tell all of them the truth of what happened the night her brother died. They were unable to protect her from the unknown. They were all three fabulous characters, but Clara was somewhat of an airhead living day to day. I really would have liked to know what happened to Margot's husband. The supporting individuals added the much needed interest and depth to the story. I highly recommend this book.

⭐️⭐️⭐️⭐️⭐️ Unputdownable! Drama, passion, and heart all in one! Single Mom’s Undoing hooked me from the very first page and refused to let go. Clara’s journey is emotional, raw, and so easy to connect with. She’s a strong, devoted mother, but seeing her face the unexpected reunion with the three silver fox alphas from her past had me absolutely captivated.

This book delivers everything I crave in a reverse harem romance—intensity, chemistry, and raw emotion—but it also weaves in drama, scandal, and family secrets that could bring real danger into their lives at any moment. Carter, Jace, and Damon aren’t just fantasy-worthy; they’re layered, complex men who each carry their own scars, which makes their love for Clara all the more powerful.

Between the sizzling tension, the shocking revelations, and the emotional depth, this story is an unforgettable rollercoaster. Kai Lesy balances heat, heart, and suspense perfectly—I would give it more than five stars if I could.

A must-read for anyone who loves second chances, found family, and romance that keeps you on the edge of your seat!.

Clara’s life is going to get better & worse
Clara ran from her hometown after seeing something she shouldn’t have. All alone and pregnant, she gets by until baby Matty develops a life-threatening heart condition. Now 4, Matty needs life-saving surgery. She returns home for some money left for her, which will help with Matty’s medical expenses. Though she hides, word gets out she’s there, and her brothers' 3 BFFs, Carter, Damon, and Jace, track her down. These guys are hot for sharing luscious Clara, and little Matty is literally one of the family. So much suspense…someone is after Clara. Lucky for her, her guys — all former military special forces — now run a successful security company. These three men are happy to share Clara and care for Matty, just as he is their son. The bad guy is typically the rich guy, and he’s a real evil monster. This is a hot story, but not blatantly in your face. Love the happy ending. Linda

[Dawn · Rating 5 out of 5]

This was such a super fun read! Romance, second chances, intrigue, and forgiveness are all front and center. Clara had to leave her life behind through no fault of her own, including the three men who loved her after the death of her brother 💔.
Returning to her hometown, she runs into the guys again, and they’re determined to keep her forever ❤️. Their relationships grow while secrets are revealed, helping everyone find forgiveness and closure.
It was also great to see Margot and Carter mend their relationship 🫂, and Matty is just the sweetest kid 🧸. A heartwarming, fun, and steamy reverse harem romance that delivers on all fronts 🌶️🔥.

[Michelle Starika · Rating 3 out of 5]

Clara falls for her brothers three best friends, gets intimate with one and then witnesses something that made her run. She can blame this on her young age all she wants, but it’s really just her stupidity. This book was way too over the top angsty for me. The entire book just pi$$ed me off. I’m giving it 3 stars because there’s a few good parts, but this just wasn’t that good to me. If it wasn’t for her needing the trust her brother set up, she would’ve never went back and also would’ve never told one of the mmc’s that he was the father of her son. Like blame you running five years ago on being young, but now she’s just plain stupid. Ugh.

I received this book with the understanding that I could leave a voluntary and honest review.

In this book we meet Clara Barnes, Carter Lockwood, Jace Wilder, and Damon Cross. When this book opens we find that Clara is standing in her son's hospital room trying to find a way to pay for surgery for him. She knows she has to go back to her home town to get help since she has no other options. What she didn't plan on was the impact of seeing Carter, Jace, & Damon again. The guys didn't realize it but they've been waiting for Clara to return. Now that she's back they will do anything to keep her. Can they all find a HEA or will outside forces make sure that never happens?

What a wild ride. I would highly recommend it to anyone.

Danger lurks everywhere and she will do anything to keep her child safe and secrets to herself.

An amazing reverse harem story. Five years ago, Clara left Blackthorne Falls but now she is back. Her son needs heart surgery to stay alive so she needs access to the trust fund her brother left her. Now as she is back, she also has to face the three men she loves. Carter, Damon and Jace were devastated when she left and now that she is back they are not letting her go. But the secret that made her leave is still there and there is one more to add to it, her sons father doesnt know he is a father. What happens when the secrets come out? Loved reading this story. Thanx.

Clara, Carter, Damon and Jace's story. Clara ran away from Carter, Damon, and Jace five years ago to save her life. Now she's back to claim the inheritance that her brother left her to save her son's life. Carter, Damon and Jace don't know the full story of why Clara left and they want answers. The past that she was running from is now back and Clara has to protect not only herself but her son and her unborn child. Can Carter, Damon and Jace get to them before its too late? This was such a good story and it does have a happy ending.

Clara returns after running 5 years ago to claim her inheritance from her brother. When Jace, Carter and Damon find out she is back, they are on her doorstep. Lots of angst, plenty of steam and action toward the end (first half of book was kind of slow) made this a fast read. Characters weren't my favorite by this author, Clara was a bit of a doormat and the guys, although they tried to be tough, just fell flat. Some of the backstory (how Clara and Carter originally got together) was missing and would have helped engage the reader.

Kai Lesy does it again with another good read! Full of suspense and spice, this book follows the story of Clara and her little boy, Matty when they must return to her hometown to get the money she needs to save her little boy. Once there, the three men she left behind show up and demand to be a part of her life. This book was hard to put down and the love the men showed Clara was intense and dedicated. Loved the happy ending!.

Clara ran 5 years ago cause it was the only thing she could do. Returning home is the last thing she ever wants to do, but she needs the trust fund she inherited from her brother for her son.
Carter, Damon and Jace were devastated by their bestfriends death and his sister their hearts love running away. Now the three will stop at nothing to make Clara stay. However the secrets that made her run are still near and very much dangerous to everyone.

A book that keeps you riveted to the very end

Action, intrigue, And love all rolled into a 1 night read. I enjoyed the characters each 1 of the 3 guys were different in their personalities but worked so well together. What attracted Her to them. If you love Women that are strong and willing to protect those she loves you're going to enjoy this book. The main character is that person That I think most of us would like to be. The men are strong sensitive and very much in love. But they have a lot of obstacles in their way and they conquer all of them for a happy ever after.

Once I started I couldn't put it down. There were some tears, a lot of laughter, especially when the men get possessive. You are mine and you will not leave me.
Clara is only in town long enough to claim her trust fund, in and out without anyone knowing. But the men do not let her get away. She left once without saying goodbye, she won't get away again.

This book sucks you in from the beginning. Clara was trying to get in and out of town before anyone knew she was there. Unfortunately that didn’t work and Carter Jace and Damon are all gone for her. There are secrets galore, twists and danger surrounding her. This book is great and I loved it but sometimes Clara’s decisions boggled me and annoyed me. Overall great book.
