This book is mean. Like, genuinely, deliciously mean in a way that made me feel like I was watching a telenovela through the lens of a Bravo reality show, and I was absolutely riveted while also kind of hating everyone in it.
I started The Favorite Sister on a Tuesday night while reworking a brand identity for a wellness startup - the irony of designing serene sage-green mood boards while listening to women absolutely destroy each other was not lost on me. Diego was on my lap, Frida was perched on the monitor judging me, and Jessica Knoll was dragging me through the most toxic sister dynamic I've encountered in audio form in a long time.
These Women Will Ruin Your Week (In the Best Way)
Brett and Kelly are sisters in the way that only sisters can be - bound by blood and sharpened by resentment. What got me was how Knoll doesn't let either of them be the sympathetic one. You keep waiting for the "good" sister to reveal herself, and she just... doesn't. Brett's meteoric success and her carefully curated feminist brand on the Goal Diggers reality show? Built on lies. Kelly's desperation to claw her way onto the show and into proximity with her sister's money and fame? Ugly and calculating. And the way the book slowly peels back whose version of events you should trust - I spent a solid five hours convinced I knew who the villain was and then got turned completely around.
The "appalling secret" the synopsis teases? When it lands, it's not a twist so much as a slow dawning horror. Knoll doesn't go for the dramatic reveal. She lets you sit in the discomfort of knowing something is deeply wrong before confirming it, and that restraint is what makes it hit so hard. I didn't ugly-cry at this one - this isn't a crying book. This is a book that made me put down my stylus and stare at the wall for a minute. Different kind of gut punch.
Three Narrators, Two That Shine, One That...
Okay, here's the thing. Three narrators: Aja Naomi King, Ashlie Atkinson, and Jenni Barber. And the casting is smart - having distinct voices for these women who are all performing versions of themselves (for the cameras, for each other, for the reader) reinforces the whole unreliable-narrator-times-three structure. King brings this controlled intensity that works perfectly for the kind of woman who's built an empire on appearing effortless. Atkinson channels real bitterness, the kind that lives in your chest, and her anger scenes don't feel performed - they feel felt.
But. And I hate to say this. One of the narrators has this vocal quality - a slight lisp, a softness in delivery that some listeners have described as a "baby voice" - that pulled me out of the story more than once. I'm someone who listens at 1.0x because I want to live inside the narration, and when a voice pulls you out instead of pulling you in, you feel it. It's not a dealbreaker, but during a 15-and-a-half-hour listen, there were stretches where I had to actively refocus. That's a lot to ask.
The emotional delivery across the board is strong when things get heated - nobody's holding back on the angst and the venom. But the quieter moments, the manipulations that happen in soft voices? That's where the inconsistency shows.
Fifteen Hours Is a Lot of Poison
I need to talk about pacing because at 15 hours and 37 minutes, this book asks for commitment. And honestly? The middle drags. The reality TV filming sequences and the constant jockeying for position among the cast members - there are stretches where it feels like you're actually watching a reality show, which means manufactured drama that goes in circles before anything actually moves. Knoll is clearly satirizing the genre, and she's sharp about it, but satire that takes its time can start to feel like the thing it's mocking.
The final act, though. The last few hours where the filming weekend unravels and the murder mystery framework snaps into focus? That's where the 15-hour investment pays off. She's been planting seeds the entire time, and watching them bloom into something genuinely dark was satisfying in the way only a slow build can be.
Abuela would have gasped at this one - not because it would've shocked her (telenovela veterans are unshockable) but because the sister betrayal runs so deep and so ugly. She always said blood doesn't mean loyalty. This book agrees.
Who Gets a Ticket to This Mess
If you love morally bankrupt women, reality TV culture dissected with a scalpel, and mystery structures where the "who" matters less than the "why" - this is your book. If you need someone to root for, walk away. There is no hero here. And if narrator voice quirks are a dealbreaker for you, maybe sample the audio first before committing a credit to 15+ hours. The social performance and class anxiety in Blue Cross scratched a similar itch for me - women constructing versions of themselves for an audience, and the ugly machinery behind the facade.
This book felt like scrolling through someone's perfectly curated Instagram and then reading their private DMs. Glamorous on the surface. Rotten underneath. And I couldn't stop listening.
