There are family reunions, and then there are family reunions where everyone has casually workshopped how they’d get rid of Grandma. For the Devi family, jokes about doing away with their formidable matriarch have basically become a love language. Nobody means it. Nobody takes it seriously. That is, until Grand Mom announces she’s changing her will, and someone almost flattens her with a car days later. Suddenly those jokes land a little differently.
Dinesh Thiru’s My Killer Family Reunion is a young adult mystery that throws an enormous, chaotic Indian American family, a fortune’s worth of inheritance drama, a teenage crush, cultural identity, and a genuinely dark streak of humor into one lavish manor and lets it all collide. It reads like Knives Out wandered into a family reunion where everybody already knows way too much about everybody else, and half of them owe each other money!
Book Overview: My Killer Family Reunion
Content Warnings: domestic violence, homophobia, sexism, vehicular accidents, loss of a pregnancy, and death of a loved one
Summary: There are three things Jayshree Devi can count on happening at her annual family reunion: 1) her cousins will forget she exists, 2) her aunts will try to set her up, and 3) her uncles will get into a fight. What she doesn’t expect? An accident that lands her grandmother in a coma, throwing the family—and their matriarch’s sizeable fortune—into chaos.
When Jay discovers Grand Mom’s “accident” might not have been so accidental after all, she’ll have to dig through decades of secrets to find the truth. With the help of her (annoyingly perky) cousins and one of their (annoyingly hot) friends, Jay finds herself knee-deep in a mystery that’s even more tangled than her family tree.
But the closer Jay gets to answers, the closer she gets to finding her place amongst the relatives who once felt so distant. With Grand Mom’s life and fortune hanging in the balance, can Jay save her family and maybe hook up with a hottie while she’s at it?
So Who Wants Grand Mom Gone, Exactly?
At the center of the mess is sixteen-year-old Jayshree Devi, who is used to being the cousin nobody remembers. She’s not the loudest, not the golden child, not the one the aunties fuss over. She fades into the wallpaper at every reunion. But when Grand Mom’s “accident” leaves her in a coma, Jay starts to suspect that somebody actually tried to kill her. And if somebody wanted Grand Mom dead, well, take a number.
Grand Mom is sitting on millions in property in India, and she’s just announced she’s rewriting her will to leave those three properties to only three family members. Cue every awkward interaction suddenly carrying a motive. Every old argument looks suspicious. Every cousin might be hiding something, and every family secret seems to unlock another one underneath it.
The Family Is The Real Main Character Here
What makes this work is that Thiru never lets the Devis become a lineup of cold, calculating suspects. They’re loud and messy and affectionate and deeply, relentlessly connected. They bicker constantly, but you never doubt that these people actually love each other, and that contradiction is where the whole book gets its charm.
There are a lot of them, though, and that’s both the book’s biggest strength and its trickiest hurdle. The cousins, aunties, uncles, parents, and various romantic side quests can be a lot to hold in your head early on. Thankfully there’s a family tree, which you will absolutely be flipping back to. Even with it, keeping track of who’s related to whom gets genuinely tangled once the mystery kicks into gear. But honestly, that crowded feeling fits. This isn’t a tidy five-suspects-in-a-locked-room affair. It’s a sprawling reunion where everyone has history with everyone, and somebody’s cousin is somehow also your cousin.
The Culture Isn’t Set Dressing
One of the things we loved most is how Thiru folds Tamil and Indian American traditions, food, family expectations, and generational push-and-pull into the story instead of parking Jay’s identity in the background as flavor. It’s specific and lived-in, and it’s a huge part of why the book feels like more than its premise.
Jay’s own arc gives all the chaos an emotional spine. She starts out feeling invisible, and as she digs into Grand Mom’s attempted murder, she slowly gets bolder, more sure of what she notices, and more willing to actually say it out loud. The mystery isn’t only about who tried to off Grand Mom. It becomes Jay’s way of working out where she fits in her own family and what she’s capable of on her own. That coming-of-age thread matters, because without it this could’ve been a flat inheritance whodunit. Instead, Jay’s journey gives the whole thing a heartbeat.
And Yes, There’s Plenty Of Mystery
Thiru keeps things moving with red herrings, shady behavior, buried history, and fresh threats against Grand Mom piling up. It’s fast and twisty, and it wants you side-eyeing everyone. It doesn’t all land equally, though. Some of the connections between clues get a little clunky, and the sheer number of subplots occasionally waters down the suspense. And if the setup feels familiar, that’s fair. The book leans openly into the Knives Out meets Never Have I Ever comparison: mansion and dysfunctional family and everyone’s-a-suspect and all. But for us the appeal was never about reinventing the family murder mystery. It’s about wrapping that familiar frame around a different family and letting Jay’s perspective and relationships steer.
The romance is probably the most skippable piece. Jay’s back-and-forth with Hernando is sweet enough and adds a little texture to her teenage summer, but it never quite pulls its weight next to the family and the mystery. The book doesn’t really need it. Its strongest relationships are the complicated ones Jay already has with her own people.
There’s heavier material humming under the comedy too, including family trauma, abuse, homophobia, gender expectations, and power imbalances. Thiru doesn’t drop the playful tone when he gets near them, and their presence gives the story more weight than the outrageous premise lets on. Some of that heavier material feels a little underdeveloped, which is probably the cost of juggling this many storylines at once.
The Mystery Gets You In, The Family Keeps You There
Still, this book knows exactly what it wants to be. It’s fast, funny, and gleefully over the top. It wants you suspecting everyone, laughing at relatives casually brainstorming ways to bump off their grandmother, and getting weirdly invested in Jay, right up until you realize there’s a real story about identity, belonging, and finding your voice buried under all the ridiculousness.
What we especially appreciated is that the book never treats dysfunction as proof that a family is broken. The Devis are chaos incarnate, but the affection is real. Their reunion is stuffed with secrets and grudges and also food, teasing, matchmaking, arguments, inside jokes, and the kind of bizarre traditions that only make sense when you’ve known the same people your whole life. That’s what gives it warmth.
If you want a tightly plotted, deadly serious thriller, this probably isn’t your read. Too many characters, too many secrets, too much happening for that kind of streamlined precision. But if you love character-driven YA mysteries, eccentric families, real cultural specificity, humor, and a dash of romance, the Devis will have you! Because somewhere between the attempted murder, the inheritance drama, the awkward matchmaking, and Jay’s increasingly confident sleuthing, My Killer Family Reunion makes a surprisingly sweet case: sometimes the people most likely to drive you completely up the wall are also the ones you’d do just about anything to protect.
Just maybe don’t let them anywhere near your will…
A dark comedy with a great big heart, My Killer Family Reunion proves that no locked-room thriller could ever be as gloriously tangled, or as fiercely loving, as a real family.
