"A taut, rapidly paced thriller that pleasurably subverts serial killer and sisterhood tropes for a guaranteed fun afternoon." --HUFFINGTON POST

"It's Lagos noir--pulpy, peppery and sinister, served up in a comic deadpan.... This book is, above all, built to move, to hurtle forward--and it does so, dizzyingly. There's a seditious pleasure in its momentum. At a time when there are such wholesome and dull claims on fiction--on its duty to ennoble or train us in empathy--there's a relief in encountering a novel faithful to art's first imperative: to catch and keep our attention... This scorpion-tailed little thriller leaves a response, and a sting, you will remember." --THE NEW YORK TIMES

"Campy and delightfully naughty.... A taut and darkly funny contemporary noir that moves at lightning speed, it's the wittiest and most fun murder party you've ever been invited to." --SAM IRBY, MARIE CLAIRE

"Braithwaite's writing pulses with the fast, slick heartbeat of a YA thriller, cut through by a dry noir wit. That aridity is startling, a trait we might expect from someone older, more jaded--a Cusk, an Offill. But Braithwaite finds in young womanhood a reason to be bitter. At the center of these women's lives is a knot of pain, and when it springs apart, it bloodies the world." --NEW REPUBLIC

"This riveting, brutally hilarious, ultra-dark novel is an explosive debut by Oyinkan Braithwaite, and heralds an exciting new literary voice... Delicious." --NYLON

"You can't help flying through the pages.." --BUZZFEED

"Feverishly hot." --PAULA HAWKINS, author of GIRL ON THE TRAIN

"Lethally elegant." --LUKE JENNINGS, author of KILLING EVE: Codename Villanelle

"Disturbing, sly and delicious." --AYOBAMI ADEBAYO, author of STAY WITH ME

"Oyinkan Braithwaite is rewriting the slasher novel, and man, does it look good. My Sister, The Serial Killer is a wholly original novel where satire and serial killers brush up against each other... A terrific and clever novel about sisterhood and blurred lines of morality." --REFINERY29

"A rich, dark debut. . . . Evocative of the murderously eccentric Brewster sisters from the classic play and film "Arsenic and Old Lace," . . . Braithwaite doesn't mock the murders as comic fodder, and that's just one of the unexpected pleasures of her quirky novel. . . . A clever, affecting examination of siblings bound by a secret with a body count." --BOSTON GLOBE

"A biting mix of wickedness and wit, Oyinkan Braithwaite weaves her narrative with a confidence that you've never read anything quite like it." --INSTYLE

"Braithwaite's blazing debut is as sharp as a knife...bitingly funny and brilliantly executed, with not a single word out of place." --PUBLISHERS WEEKLY, (starred review)

"Strange, funny and oddly touching...Pretty much perfect...It wears its weirdness excellently." --LITHUB

"Who is more dangerous? A femme fatale murderess or the quiet, plain woman who cleans up her messes? I never knew what was going to happen, but found myself pulling for both sisters, as I relished the creepiness and humor of this modern noir." --HELEN ELLIS, author of AMERICAN HOUSEWIFE

"A gem, in the most accurate sense: small, hard, sharp, and polished to perfection. Every pill-sized chapter is exemplary." --EDGAR CANTERO, author of MEDDLING KIDS

"Sly, risky, and filled with surprises, Oyinkan Braithwaite holds nothing back in this wry and refreshingly inventive novel about violence, sister rivalries and simply staying alive." --IDRA NOVEY, author of THOSE WHO KNEW
