Etna vs. My Sister Is Going to Kill Me for Book Club
"My Sister Is Going to Kill Me" will get every member of your club to actually finish the book by meeting night. "Etna" will get them arguing about it after they close the last page. Most clubs default to the first kind of pick every single month and then can't figure out why their discussion dies at the ten-minute mark. You don't have to choose between the two forever — you just have to know which one you're picking, and why.
Nina Simon's "My Sister Is Going to Kill Me" (William Morrow, August 18, 2026) is a fast, plotted Grand Canyon rafting mystery from the author of the Reese's Book Club hit "Mother-Daughter Murder Night" — pick it when your club needs a guaranteed finish. Paul Yoon's "Etna" (Scribner, August 4, 2026), the American Booksellers Association's #1 Indie Next List pick for August, is a spare, dog-narrated war novel — pick it when your club is hungry for a real fight over what the book actually means.
The books, side by side
These two aren't competing for the same reader. They're not even really competing for the same night. Here's what you're actually choosing between.
Will your club actually finish it
This is the dimension most pick-of-the-month lists skip, and it's the one that decides whether your meeting has anything to discuss at all. "My Sister Is Going to Kill Me" is 352 pages of a plotted mystery with a body count, a countdown (the raft trip has a fixed number of days), and short chapters that keep the pages turning almost against your will. If your club has members who read on their phones during lunch breaks or squeeze in twenty pages before bed, this is the format built for that. Nobody shows up on meeting night having read the first sixty pages and stalled — the structure won't let them.
"Etna" is a different kind of book to live with. It's slim, but it's slow in the way spare, image-driven prose is slow — you can't skim it the way you can skim a thriller, because the sentences are doing more work per word. Some readers will finish it in one sitting and call it the best hundred and some pages they've read all year. Others will put it down after two chapters because nothing "happens" yet, by their definition of happening. If your club runs on momentum and instant gratification, that's a real risk. If your club has members who complain that every pick lately has felt disposable, it's exactly the corrective they've been asking for.
What actually happens at the meeting
Here's the trade nobody says out loud: a plotted mystery is satisfying to read and thin to discuss. Once you've established who did it and why, there isn't much left to argue about — the book already told you the answer, and disagreeing with a solved mystery just means someone didn't read closely enough. "My Sister Is Going to Kill Me" will generate the fun, easy kind of book club conversation — guessing who you suspected, laughing about the sister dynamic, maybe planning your own rafting trip. It's a great night. It's rarely a night anyone remembers a year later.
"Etna" doesn't resolve anything the same way, which is exactly what makes it combustible. A dog narrator forces every reader to decide, individually, how much anthropomorphizing they're willing to accept — and that decision colors everything else about how they read the book's politics, its silences, its refusal to name the war it's set in. You will get people who think the animal narration is the most devastating choice Yoon could have made, and people who think it's a gimmick keeping the book from saying anything directly. That gap is where real book club discussion lives. If your last three meetings wrapped up in twenty minutes because everyone basically agreed, "Etna" is the pick that breaks that streak.
So which one do you actually pick
Neither book is the "better" book club book in the abstract — they're built for different jobs. If your group is coming off a rough stretch of DNFs, or you've got new members who need a win to stay engaged, open with a plotted thriller that respects everyone's time, and "My Sister Is Going to Kill Me" is one of the strongest options released this August. If your group is bored, has been coasting on beach reads, or keeps saying "we never really disagree about anything," reach for something with more friction built in — the kind of pick you'll find alongside "Etna" on any list of literary fiction that actually earns a two-hour conversation.
The mistake is picking the same type every single time and being surprised when the results repeat. A club that only ever reads propulsive mysteries will eventually notice its meetings have turned into plot recaps. A club that only ever reads demanding literary fiction will eventually lose the members who read for escape, not homework. Alternating — a page-turner one month, a debate-generator the next — is the actual strategy, and it's worth building into however your club chooses its books going forward rather than defaulting to whatever's trending.
