In this deliciously incisive (Publishers Weekly) debut, a young woman finds herself inexorably drawn to repeating the worst mistakes of her past, for readers of Marlena and Social Creature. An utterly taut construction, as unsettling as it is propulsive . . . McCarthys debut, with the acumen of the best literary fiction and the suspense of a psychological thriller, is a marvel.--Kirkus Reviews Masterly, mendacious, and a total thrill ride . . . Not since a certain Mr. Ripley have I been so consumed in anothers 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 friends strange charisma, Rose convinces Lacie to let her move in, and the two fall into an intense, uneasy friendship. While tutoring the offspring of Manhattans 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 Lacies 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 Lacies 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.
