In this “tale of toxic friendship at its most riveting” (People), a young woman finds herself inexorably drawn to repeating the worst mistakes of her past.

“Masterly, mendacious, and a total thrill ride . . . Not since a certain Mr. Ripley have I been so consumed in another’s covetous desires.”—Justin Torres, bestselling author of We the Animals

At age thirty, Rose is fierce and smart, both self-aware and singularly blind to her power over others. After moving to New York, she is unexpectedly swallowed up by her past when she reunites with Lacie, the former best friend she betrayed in high school. Captivated once again by her old friend’s strange charisma, Rose convinces Lacie to let her move in, and the two fall into an intense, uneasy friendship.

While tutoring the offspring of Manhattan’s wealthy elite, Rose works on a novel she keeps secret—because it stars Lacie and details the betrayal that almost turned deadly. But the difference between fiction and fact, past and present, begins to blur, and Rose soon finds herself increasingly drawn to Lacie’s boyfriend, exerting a sexual power she barely understands she possesses, and playing a risky game that threatens to repeat the worst moments of her and Lacie’s lives.

Sharp-witted and wickedly addictive, Everyone Knows How Much I Love You is a uniquely dark entry into the canon of psychologically rich novels of friendship, compulsive behavior, and the dangerous reverberations of our actions, both large and small.
“A tale of toxic friendship at its most riveting.”People

“An utterly taut construction, as unsettling as it is propulsive . . . McCarthy’s debut, with the acumen of the best literary fiction and the suspense of a psychological thriller, is a marvel.”Kirkus Reviews

Everyone Knows How Much I Love You is breathless and precise at once, utterly gripping, animated by the propulsive unfolding of hungers that can't be controlled or fully fathomed. It aches with insight and longing. It seduced me from the very first page with the pull of its own fierce gravity, like a darkly turning planet—its atmosphere swirling with mysterious, combustible desires; its truths merciless and bone-deep.”—Leslie Jamison, New York Times bestselling author of Make It Scream, Make It Burn

“Everyone Knows How Much I Love You is masterly, mendacious, and a total thrill ride. I was hooked instantly, laughing alongside Rose, alternately cheering and chastising her entanglements and escalations. McCarthy is an edgy writer and the prose is all at once darkly comic, sexy, and razor-sharp in its psychological insights. Not since a certain Mr. Ripley have I been so consumed in another’s covetous desires.”—Justin Torres, bestselling author of We the Animals

“A suspenseful, sexy, and gorgeously written excavation of best-friend envy. I read it with horror. And recognition. And great delight.”—Michelle Huneven, author of Blame and Off Course

“This novel gripped me from its first page. A New York story crackling with obsession; a dizzying, daring tale of lives shaken to their foundations by the tumultuous interplay of sex, death, and art, McCarthy’s debut leaves an indelible mark on the reader’s sense of the world. Unforgettable.”—Evan James, author of Cheer Up, Mr. Widdicombe

“A wickedly smart, deeply readable novel about art, love, and friendship.”—Caroline Leavitt, New York Times and USA Today bestselling author of Cruel Beautiful World

“A fascinating exposé of the twisted, porous lines that separate brilliance from insanity, self-awareness from misperception, and love from obsession. McCarthy meanders through the complexities of a lifelong friendship and lingers on brutally honest moments of female desire and longing, adding her voice to the glorious chorus of modern-day feminist authors.”—Wendy Walker, nationally bestselling author of The Night Before

“Compulsively readable.”—Marcy Dermansky, author of Very Nice

“Ever since I finished Everyone Knows How Much I Love You, I haven’t stopped thinking about it: how the prose pops and fizzes; how the characters reside in my mind still like ants in a terrarium; how McCarthy masterfully articulates aspects of the female experience I’ve always intuited but haven’t seen in print. It’s a stunning, evocative, unflinching debut, and I can’t wait to read whatever she writes next.”—Andrea Bartz, author of The Lost Night and The Herd
