Okay, I need to rant for a second. The AUDACITY of this book's ending. I was lying on my yoga mat — not doing yoga, obviously, just stretching my back because eight hours hunched over a client's rebrand will wreck you — and I had maybe twenty minutes left, and I was fully invested, and then... that. That ending. I actually said "are you KIDDING me" out loud and Diego jumped off the windowsill. Frida didn't move because Frida fears nothing.
But let me back up.
The Telenovela Energy My Abuela Prayed For
Listen. I grew up watching women in silk robes throw wine glasses at lying men while my abuela narrated along in Spanish, adding her own commentary like she was a producer on the show. Diary of a Mistress is that energy in audiobook form. Miasha sets up this seemingly airtight marriage — Monica and Carlos, tenth anniversary, twin sons, the whole golden picture — and then drops a literal diary into Monica's life like a grenade wrapped in gift paper. The premise is pure telenovela DNA: the other woman doesn't just exist, she writes it all down and makes sure the wife finds it.
And Angela — the mistress — isn't written as some one-dimensional villain, which honestly surprised me. She's coming off a marriage wrecked by infidelity herself, and she's spiraled into this pattern of sleeping with married men as some kind of twisted armor. When she meets Carlos, she genuinely believes this is different. You can feel her self-deception, the way she's rewriting her own story to be the love interest instead of the side character. That's the kind of emotional complexity I didn't expect from a book under five hours.
At 4 hours and 52 minutes, Miasha is working fast. The twists come rapid-fire — there were at least three moments where I literally covered my mouth with my hand while resizing vectors on screen (not great for productivity, very great for my emotional health). The pacing doesn't really let you breathe, which works for about 80% of the book. It feels like reading someone's actual diary — messy, urgent, the kind of writing where you can feel the pen pressing harder into the page.
Claudia Alick Carried This on Her Back
Claudia Alick's narration is doing serious heavy lifting here. She shifts between Monica's bewildered devastation and Angela's desperate bravado in a way that actually makes your stomach knot differently depending on whose chapter it is. When Monica finds the diary — the raw confusion in Alick's voice, that slight tremble before the anger kicks in — that's not just reading words. That's someone who understood the assignment.
She's particularly good with Angela's internal justifications. There's this cold steadiness she gives Angela when she's convincing herself that what she's doing is fine, that Carlos is basically already hers, and then these cracks appear in the delivery when reality pushes back. I wouldn't put her in Julia Whelan territory (who is?), but she gave these women distinct emotional textures, not just distinct voices.
About That Ending, Though
I'm not going to spoil it. But I am going to say: it felt like Miasha was building a house, room by beautiful chaotic room, and then ran out of materials for the roof and just... threw a tarp over it. The twists throughout the book earn their drama. They're shocking but they track emotionally. The ending doesn't do that same work. It felt rushed, like the story deserved another forty minutes it didn't get. I didn't cry — and honestly, with material this emotionally charged, that's almost a complaint. I was right there on the edge for most of the listen, but the ending yanked me out instead of pushing me over.
Abuela would have LOVED the drama of this book. She also would have thrown her chancla at the ending and said "¿y eso es todo?" And she would have been right.
Who's Going to Devour This (and Who Should Steer Clear)
If you love messy relationship drama with real emotional stakes — not just shock value but actual character motivation behind the mess — this is a rainy Sunday book for sure. Short enough to finish in one design session. But if you're someone who needs a satisfying resolution to feel like the journey was worth it, you might end up frustrated. The ride is genuinely good. The destination is... a parking lot. I had a similar "incredible journey, questionable landing" experience with Deal with the Devil — another book that kept me white-knuckling through the messy middle but couldn't quite stick the dismount.
Also: content warning for sexual content, so maybe not the one to play on speakers at the coffee shop. Headphones, friends.
The Bookmark I'm Leaving Here
This book felt like binge-watching three episodes of a telenovela and then the power goes out during the finale. I'm giving it credit for what it made me feel in the middle — that breathless, somebody's-about-to-get-caught tension — but I can't pretend the landing didn't bruise. Claudia Alick, though? She deserves flowers. Send her flowers.
