It Won’t Last Forever

Rate this book
"The saga begins with a bang in this Epic Romance Horror that will shatter your mind like a broken air raid siren!"

"
When Killian was sixteen, his world shattered in a courtroom drenched in blood, betrayal, and irreversible violence. That day, he lost everything—his freedom, his family, and the only girl he ever loved. Eight years behind bars couldn’t cage the monster inside him… nor silence the voice that lives in his head.

Now free but broken beyond recognition, Killian has one end it all. Until fate pulls him into an unexpected reunion with Kenzie, the girl whose memory has both haunted and kept him alive.

But Kenzie isn't the same rebellious teenager he left behind. She’s endured her own demons, and she’s not letting go again. As their lives collide in a storm of passion, pain, and long-buried truths, Killian must face the dark force inside him—the alter ego he calls K—before it destroys what little remains of his sanity... and the fragile hope Kenzie offers.

A brutal, heart-wrenching journey of trauma, love, and raw survival, It Won’t Last Forever is not your typical romance. It’s messy. It’s violent. It’s painfully real.

Perfect for fans of dark love stories, psychological fiction, and characters who burn through the page with emotional intensity.Graphic. Gritty. Unflinching. 18+

(A Promise from the Author)
A perfect mix of Romance and Horror. This Series has the most original concept and Storyline you will ever read; it's unlike any novel out there. If you're on the fence about this series, get off it now and order the book. The Juice is worth the squeeze, I promise.
Short wait for the rest of the series. Book 2 Releases 9/12 and Book 3 on Friday the 13th, March 2026.
There are also several planned spin-off books from this world I created. One of which will be coming out in spring 2027, called "Neon Pig," based on a villain at the end of book 2.

This isn’t your typical romance—it’s dark, raw, and will gut-punch you with emotion.

Killian’s life changed the night violence ripped his world apart. Eight years in prison left him broken, carrying scars you can’t see. Kenzie was part of that past, and when they cross paths again, it’s not a fairytale reunion—it’s messy, painful, and filled with ghosts they can’t outrun.

Told with unflinching honesty, this book dives deep into trauma, mental illness, addiction, and the brutal fight to heal. It’s not an easy read, but it’s unforgettable.

⭐ Expect:
• Psychological depth and emotional grit
• A love story born from pain, not perfection
• Themes of redemption, survival, and the cost of forgiveness

If you love stories that linger in your mind long after the last page—and don’t shy away from heavy topics—this one will stay with you.

This is must read!! Def check your triggers, cause theirs plenty in this book, but if you can get through that, this book is so worth the read.

This gut-wrenching psychological thriller will have you hooked from page one.

This book follows his story and once he is released years later fate brings him back to his lost love. But Kenzie has her secrets too. She is his light and they cannot live without each other.

Where do I even begin when it comes to this one. You have Killian and Kenzie who are the main characters. They meet when they are 14 years old and fall hard for each other from day one. They are both battling issues in there life. Kenzie has had a horrible upbringing with her mom. Killian has a battle with himself by someone he calls K he doesnt know what he is but he overpowers him but Kenzie is the calm to his storm and keeps him level headed. Even though there kids they grow together and go through hard times. Such an amazing read and I cant wait to read book two.

It Won’t Last Forever by R.M. Edenburn is a beautifully written, gripping, and emotional ride that immediately pulled me in from the very first scene.

Killian and Kenzie’s story feels intense and deeply personal, the kind of love that consumes you even when life tries to tear you apart. Their bond carries a raw, youthful energy, and despite their flaws, you can’t help but root for them. The story perfectly conveys that powerful “this is my person” feeling, the type of connection you feel in your soul long before life makes sense of it.

These two have been through so much trauma, and it makes every moment between them hit harder. Their love is messy, imperfect, and often heartbreaking, but you can see the potential for healing and growth together, which makes me even more eager for the next book.

The writing is phenomenal and full of nostalgia, and the story had me hooked all the way through.

The book ends on a gut-punch cliffhanger that left me reeling. The final scene is shocking, emotional, and impossible to shake—I closed the book and immediately wanted book two in my hands. 😭📚

This book…. For starters I walked into a local bookstore and the cover caught my attention. I read the first couple pages and to say it starts off with action doesn’t even begin to explain the ride this book takes you on. At first I wasn’t sure how I was going to like it, but I could not stop reading it. Can’t wait until the next one comes out. Will recommend.

This book was a definite shocker, with twists and components I did not expect, but it was absolutely worth the read. R.M. Edenburn does a terrific job of introducing us to Killian, Kenzie, and the infamous character of K. Through their story, you begin to see the events that shape and define their lives. The writing pulls you into all the passion, heartbreak, and raw emotion these characters endure. While there were moments that left me stunned, the overall journey kept me fully invested. A strong and engaging start that makes me eager to see where Edenburn takes this story next.

⭐️⭐️⭐️⭐️⭐️ Emotional. Twisted. Addictive.

It Won’t Last Forever completely consumed me.
Killian and Kenzie’s chemistry is everything — raw, real, and unforgettable. The romance? Heart-shattering. The mystery behind Killian’s inner voice? Chilling and impossible to ignore.

This book is dark, emotional, and utterly addicting. I couldn’t turn the pages fast enough — and that cliffhanger? RUDE.

Check your trigger warnings, then dive in. You won’t forget this story.

Be mindful of potential triggers, as the story delves into heavy and sensitive themes.

In this extraordinary tale, we meet Killian and Kenzie, two young souls who find each other at just 14 years old. From the moment they meet, they are inseparable, battling the challenges life throws at them while leaning on each other for support. As their love story evolves, it is anything but smooth. Killian's life takes a dramatic turn when a violent incident leads to his imprisonment for murder. This book is an emotional tour de force, filled with raw, heartbreaking moments and glimmers of hope.
This is not your typical romance novel. It is dark and raw, delivering a powerful punch of emotion. Killian's experiences in prison have left him scarred, both physically and emotionally. From start to finish, this book is intense and immersive. It evokes a spectrum of emotions, from the depths of anguish to the heights of all-consuming love. The story is captivating and unforgettable, leaving readers eagerly anticipating the next installment.

It Won’t Last Forever is a powerful and emotional read. It opens gut wrenchingly, with the characters being torn apart, before flashing forward eight years when fate brings them back together. At its core, it’s a story of young love and the whirlwind rush of falling fast and hard. With the hope of finding your way back to someone when the time is right.

This book took me longer to get through, not because it isn’t good (it absolutely is!) but because it’s heavy at times, tackling mental health and other intense topics. It’s one of those stories you occasionally have to set down, take a breath, and return to when you’re ready.

Having been in a relationship with someone struggling with mental illness, parts of this book hit close to home. I know what it’s like to feel like you’re constantly walking on eggshells, unsure where the line or limit is. The way this dynamic is explored here feels raw, authentic, and deeply moving.

Just when I thought I had the story figured out, an unexpected, gut wrenching, taboo twist near the end completely caught me off guard. It added another layer of shock and depth that made this book unforgettable.

If you’re looking for a romance that offers more than fluff.. A story full of depth, heartache, and beautifully flawed characters this is one worth reading. It’s beautifully written, heartbreaking, and profoundly relatable.

I was sent a copy of this book and I am so happy I read it. I really enjoyed this dark romance psychological thriller. There are quite a few parts that could be triggering to some people so please CHECK THE TRIGGERS! I actually really enjoyed the way the chapters were formatted, it was different. This is a story about young adults, but does talk about their young teenage years so keep that in mind too. The spice was spicy. The cliff hanger was dangerous. I can’t wait for book 2 of this saga!

Killian and Kenzie’s story is a raw, emotional rollercoaster. Equal parts heartbreaking, gripping, and full of hope. Meeting at just fourteen, they fall for each other instantly, forging a deep connection despite the darkness in their lives. Kenzie is shaped by a painful upbringing, and becomes the calm to Killian’s storm. But Killian carries his own demons and has an inner battle with a side of himself he can’t fully control.

When tragedy strikes and Killian is sent to prison for murder, their world shatters. Yet years later, fate brings him back to the one person who has always been his light. But time hasn’t erased the scars, and Kenzie has secrets of her own. Their journey is one of resilience, devotion, and an unbreakable bond that refuses to fade.

This captivating and gut-wrenching read will hook you from page one and leave you desperate for more. I cannot wait to start reading book two!

Killian and Mackenzie's story is defitnely chef's kiss! This is a once in a lifetime love story that is so captivating it's hard to put down! The trials and stipulations tha tlife throws at these two is so intense It's almost like the world doesn't want them to together, but yet there truly meant to be soul ties! Killian has his own nightmares and demons that he faces daily, and not to mention when he was placed in prison things didn't get easier for him, it only got worse. When Killian gets out of prison he accidently finds Mackenzie working at a vet clinic. The instant they found eachother they were head over heels, yet again. It was like as if all those years didn't pass them. Learning all the things that Killian did to save Mackenzie without her even knowing is so heart felt and genuine! I loved how the author didn't sugar coat anything and never missed a beat of all the raw real truths about the heart attacks and life struggles.

This book had potential of being a badass book. I loved the story but it did take me until half way through to get into it. I don’t DNF books and I’m glad I didn’t start with this one lol. I personally felt it took too long for us to find out the back story the MMC Killian. A lot of time was spent on what they were doing present time.

I will say the author did a great job at getting you to feel the emotions of what Killian and Kenzie were feeling. I wanted to reach into the books and give them hugs and cry with them.

I did have one word that I felt was used way too much by the FMC and that is when Kenzie was calling Killian “bay”. That had my skin crawling every time I saw that word

This book left me on a dang cliffhanger and I do plan on reading book 2 for sure

The very first line of the book HOOKS you in. For new readers: you’d be questioning everything. I kept asking myself, who is K? Right in the beginning so I kept turning the pages. The author does something unique by going right into chapter fiftyish. I can’t wait to piece it all together for book two! This was really unique.

Thank you for gifting me your book! 🤗
