Well this story just crushed me, I knew i was in for a rollercoaster of emotions with this one.
Dax and Cassandra were a disaster waiting to happen, their messy story was addicitive.
Dax Kingston isn't sweet or soft, nor is he full of tenderness and romance. He's seen to much and done worse, hes become battle hardened, unrecognisable even to himself.
Cassandra is broken on the inside, she wants Dax to fix her and she thinks she can fix him in return.
Together they are toxic, their obsession with each other is a dangerous monster. They hurt each other and come back for more.
OMG! these two, their passion and pain bled from the pages. Their tremulous love story left me emotionally exhausted. They both have underlying trauma, their love is a battlefield of chaos and unresolved issues. Their relationship isn't healthy but it's powerful, raw and all consuming.
That ending..... I'm left tormented with what ifs.
It was never going to end well but i still need to know more.
I wanted a story to make me feel and i definetly got it with Goodbye Butterfly. 🖤

I am completely lost for words, this book had me going through the entire emotional spectrum. I was bawling my eyes out from start to finish and I could not take my eyes off the page!
I haven’t read a military romance with such a good depiction of PTSD and what it truly does to a person, and that part of what made this book so special and so heartbreaking.
It’s also their entire relationship is built on broken trust but this odd addiction to each other because they make each other feel better.
This book made me an emotional wreck and I’d don’t think I’ll ever recover from this. There are so many amazing plot twists and that cliffhanger was just brutally insane. I can’t wait for the next book!.

Consider this your warning.
Goodbye Butterfly is not a pretty story with a pretty bow.
It’s messy.
It’s sharp.
It digs under your skin and whispers all the things you’re afraid to admit.
Dax is the storm.
Cassandra is the wreckage.
And the two of them together?
A disaster you’ll beg to watch unfold.
If you want safe love — skip this.
If you want a book that grabs you by the throat and makes you feel — welcome home.

🦋 Goodbye Butterfly — A Love That Breaks More Than It Heals
⭐️ 4.5 Stars
If you’re looking for a soft love story, this isn’t it. But if you want a book that will emotionally wreck you, Goodbye Butterfly is exactly that. Please check trigger warnings before reading.
This story lives in heartbreak. It’s dark, painful, and centered around two deeply broken souls who don’t heal each other so much as unravel together. Dax is a military man suffering from severe PTSD—his world is filled with screams, blood, and death. Cassandra is just as fractured, desperately wanting to escape the pain inside her own mind. She believes Dax is the one person who can complete her, and in many ways, she’s right… even if that connection comes at a cost.
As the story progresses, I did feel like certain moments became repetitive—Cassandra constantly asking Dax to ruin her, and Dax repeatedly insisting he needs to stay away while inevitably coming back. I genuinely think the book would have flowed better if some of those repeated sections were trimmed down, making the story tighter and more impactful.
That ending, though? Absolutely devastating. I finished the book staring at the final sentence thinking, how the fuck do you leave it like that? I wanted—no, needed—more. An extra scene, anything. It left me completely reeling.
This was my first book by Calia Quinn, and it definitely won’t be my last. I received this as an ARC, but I fully plan on buying a physical copy because this book deserves a permanent place on my shelf. I’m so glad I got to experience this story.
