27 Juli Writing a Hero with PTSD: What I Learned Writing Cole Diver
The Walls We Break is relaunching soon, and I keep coming back to the same thought about the man at the center of it: Cole Diver was the hardest character I’ve written, and I think that’s exactly why readers have connected with him.
Cole is a former Army Staff Sergeant who came home from Afghanistan with PTSD, insomnia, and a guilt over the loss of his squad that he’s never spoken about out loud. He works. He keeps a routine. He keeps his life small on purpose, because small is survivable. And then Savannah Morris moves back to town, and small stops being enough.
Here’s what I actually had to think through to write him.
His trauma isn’t the plot. It’s the terrain.
The easiest mistake to make with a wounded hero is turning his PTSD into a twist to be revealed, or a wound the heroine magically heals with love. I didn’t want Cole’s trauma to be a secret he’s hiding — everyone in Glasswater already knows what happened to him. What they don’t know is what it costs him, to function like a person who isn’t still there.
So instead of a reveal, his PTSD is the terrain the whole relationship has to move through. It shapes how he shows up. He can’t stand surprises, he needs control over small things like closing a door or setting down a tool in the same place every time, how intimacy itself is a risk to the careful architecture he’s built to survive.
Savannah doesn’t fix him.
This was the line I worked hardest to hold. Savannah isn’t there to heal Cole — that’s not her job, and frankly, it’s not fair to ask a heroine to carry that weight, or a hero to need it. What she offers instead is something smaller and, I’d argue, more real: she lets him exist exactly as he is, without flinching and without trying to manage him into a better version of himself.
That’s what their friends-with-benefits arrangement is actually protecting, underneath the „no feelings“ rule they set. It’s not really about avoiding romance. It’s about avoiding the vulnerability of being truly seen by two people who, for very different reasons, have learned that being seen is dangerous.
The question I kept asking myself: what would actually help him, versus what would just look romantic on the page?
It would have been easy to write a big cinematic moment where Savannah says the right thing and Cole’s walls come down. That’s not how this kind of healing works, and I didn’t want to lie to readers about it. Real trust-building with someone carrying trauma is unglamorous — it’s showing up consistently, it’s not pushing when he goes quiet, it’s letting the relationship be slower than either of them wants it to be.
If you’ve read the book, you know the moment I mean — the one that isn’t loud at all. That was the one I was most nervous about, and it’s become the one readers message me about most.
Why I think it resonates
I hear from readers — some who’ve dated someone with PTSD, some who’ve lived with it themselves — that Cole felt real to them in a way they didn’t expect from a romance hero. I think that’s because I tried, as hard as I could, to write his healing as something he has to choose again and again, not something that happens to him because a woman loved him hard enough.
„Can you love me at my worst?“ is the question underneath The Walls We Break, and I wanted the answer to feel earned, not automatic.
The relaunched edition is coming very soon — if you’ve read it before, I’d love to hear which part of Cole’s arc landed hardest for you. If you haven’t yet, this is your sign.
