This book should be required reading for anyone who's ever loved someone with BPD and felt like they were losing their mind in the process.
I don't say that lightly. As someone who studies how people construct narratives about their relationships—and how those narratives can trap them—I found Shari Manning's approach genuinely refreshing. She's not here to pathologize your loved one. She's not here to tell you to run. She's here to hand you actual tools, grounded in dialectical behavior therapy, and say: here's what's happening in their brain, and here's what you can do about it.
The Psychology Actually Tracks
Look, I've read a lot of books about personality disorders that make me want to throw things. Either they're so clinical they forget there's a human being on the other end, or they're so pop-psychology that the advice is basically "just love them harder!" (My therapist would have thoughts about that approach.)
Manning does something different. She explains the emotional dysregulation at the core of BPD in a way that's accessible without being condescending. The research shows that people with BPD often experience emotions more intensely and for longer periods—and Manning uses this framework to help you understand why your partner or family member might seem to flip from adoring you to despising you in the span of an afternoon. It's not manipulation. It's not a choice. It's a fundamentally different experience of emotional reality.
What I found myself asking while listening: why doesn't everyone talk about BPD this way? Manning understands human nature—both the person with the disorder AND the exhausted loved one trying to hold it all together. She validates your frustration without letting you off the hook for your own reactions. That's a hard balance to strike.
Angela Brazil's Delivery (With One Caveat)
Brazil is an AudioFile Earphones Award winner, and her delivery is clear, professional, soothing even. For a nearly 11-hour psychology book, you need someone who won't grate on your nerves, and she mostly delivers.
But—and I genuinely hate that I have to mention this—there are audible swallowing sounds. After paragraphs. Consistently. I listened to this during my morning jogs through Cambridge, and once I noticed it, I couldn't un-notice it. Not a dealbreaker, but if you're someone who gets distracted by audio artifacts, consider yourself warned. One listener described it perfectly: "she has a lot of it." (Saliva. They meant saliva. I know.)
The narration itself is competent rather than captivating. Brazil doesn't do anything wrong, exactly—no weird pronunciations, no strange pacing choices. But this isn't the kind of performance that elevates the material. It's more like a very good audiobook version of having a knowledgeable friend read you a textbook. Which, honestly, for this kind of content? Works fine.
You're the Protagonist Here
Manning isn't promising you'll fix your loved one. She's promising you can change how YOU respond, which changes the dynamic, which—maybe, hopefully—creates space for something better.
That's the same reframing Untamed does—putting you at the center of your own narrative instead of making you a supporting character in someone else's chaos. And what makes this book compelling is that Manning treats you like an adult who can handle hard truths. Your loved one's behavior isn't your fault. But your reactions might be making things worse. Both things can be true.
I found the sections on setting boundaries particularly useful—not the vague "set healthy boundaries!" advice you get everywhere, but actual scripts. Actual language. The kind of stuff you can practice in your head before the next crisis hits. (And if you're listening to this book, there will be a next crisis.)
Psychologically, this tracks. DBT works. The evidence base is solid. Manning knows her stuff—she's been treating BPD since 1993 and worked with Marsha Linehan's organization. This isn't someone who read a few papers and decided to write a book.
Who Needs This (And Who Doesn't)
If you're in a relationship with someone with BPD and you're exhausted, confused, and wondering if you're the crazy one—this is for you. Skip it if you're looking for a quick fix or want permission to leave; Manning's interested in neither. Also skip if mouth sounds in audio genuinely bother you.
My Prescription
Honestly? I could see returning to specific sections when I need a refresher on how to handle certain situations. (Yes, I'm being vague about why. No, I'm not going to elaborate. Some things stay between me and my therapist.)
This book won't fix everything. But it might help you understand what's actually happening. And sometimes understanding is the first step toward something that looks a little more like peace.
Just maybe listen at 1.25x speed. The pacing is measured, and you've got nearly 11 hours ahead of you.
