"I will spend my last breath looking for you."
That line hit me somewhere around hour seven, and I had to put down my stylus because my hands were shaking. I was in the middle of finalizing a logo mockup for a client — deadline breathing down my neck — and Murphy Shepherd just wrecked me with six words. Frida looked up from the desk like, "Again?" Yes, again. Diego didn't even bother.
Murphy Shepherd Carries the Weight of the World and I Let Him Carry Mine
So here's the thing about The Letter Keeper — it's book two in the Murphy Shepherd series, and Charles Martin does this thing where he writes action-thriller bones but wraps them in so much emotional sinew that you forget you're reading a rescue mission. Murphy's wife, her daughter, and two teenage girls get taken by traffickers, and the whole book is basically this man dismantling himself piece by piece to get them back. But it's not Jason Bourne energy. It's... quieter than that. More desperate. Murphy prays. He doubts. He writes letters he doesn't know if anyone will ever read. I've been chasing that same quality — a character whose interior life is as fully rendered as their exterior crisis — and I found traces of it in Breakfast with Buddha, where the faith element is also genuinely load-bearing rather than decorative. There's a scene — chapter 39, about two and a half minutes in — where Murphy opens his eyes and whispers a Bible verse, and it's so small and so broken that I had to pause the audio and just sit there.
I'll be honest: I'm not a particularly religious person. Abuela was. She would have eaten this book alive and then gone to light a candle at San Fernando Cathedral for Murphy's soul. The faith elements are woven into the story like thread through fabric — you can't pull them out without unraveling the whole thing. And Martin doesn't use faith as a shortcut or a band-aid. Murphy's belief costs him something. It hurts. That's what made me trust it.
Jonathan K. Riggs Understands the Assignment
Riggs has narrated the whole Murphy Shepherd series, and you can feel the continuity in his bones. His voice has this low, steady warmth that makes Murphy sound like a man who's been tired for a very long time but refuses to stop moving. What I love — and this is specific — is how he handles the letters Murphy writes. There's a slight shift, almost imperceptible, where his cadence slows and his tone drops into something more intimate, like he's reading to you and only you. It's not performative grief. It's the real kind. The kind where someone's voice gets quieter instead of louder.
Where Riggs really earned my respect is the tension scenes. There's violence in this book — the trafficking content is not sanitized, and it shouldn't be — and he doesn't melodramatize it. He lets the words do the heavy lifting. A lesser narrator would have gone big and dramatic during the rescue sequences. Riggs stays controlled, almost clinical, which makes the emotional breaks hit that much harder.
At 1.0x speed (because I'm savoring, always), Riggs fills almost ten hours without a single moment where I wanted to skip ahead. That's rare.
The Part Where I Talk About Crying (You Knew This Was Coming)
Three crying sessions. THREE. And not the pretty kind — the kind where you're holding a tissue and your cat is staring at you and you have to text your best friend "DO NOT TALK TO ME I AM PROCESSING."
The first was during a flashback scene with Murphy and Summer early in their relationship, which Martin uses to devastating effect because you already know what's been taken. The second was chapter 39 (see above, I'm still not okay). The third — and this one surprised me — was during a scene with one of the rescued girls. I won't spoil it but Martin writes trauma recovery with a gentleness that doesn't feel patronizing. It felt like watching someone learn to breathe again.
This book felt like sitting in Abuela's living room during a thunderstorm. Scary outside, warm inside, and someone you love telling you it's going to be okay even when they're not sure it will be.
Who Needs This in Their Ears
If you loved The Water Keeper, this is the emotional payoff you've been waiting for. If you haven't read book one — go back. You need the foundation or the gut punches won't land as hard. If you're uncomfortable with Christian faith as a central character motivation (not just window dressing — central), this might not be your book, and that's okay. If trafficking content is triggering for you, please take care of yourself — Martin doesn't exploit it, but he doesn't shy away either.
But if you want a book that will make you believe that one stubborn, broken man's love can move mountains? My heart. MY HEART.
Abuela would have loved this one.
