From New York Times bestselling author Benoit Denizet-Lewis comes a timely, provocative, and deeply moving exploration of personal transformation in a period of roiling uncertainty. You’ve Changed investigates how we remake ourselves—and how identity, belief, and belonging shift in a world that won’t stop doing the same.

We live in an age obsessed with reinvention. On Instagram, in recovery meetings, through name-change petitions, lifestyle pivots, deconversion blogs, and political conversion manifestos, we’re surrounded by stories of radical personal change. But what does it really mean to shed an old skin—and why do some transformations inspire us while others raise our hackles?

Longtime New York Times Magazine writer Benoit Denizet-Lewis, known for his deeply reported and psychologically rich journalism, takes us on a freewheeling, wild-hearted journey into the mystery of human transformation. He introduces us to an unforgettable array of people in flux—including psychedelic reality benders, sexual and gender transitioners, ideological shapeshifters, seemingly reformed murderers, and an octogenarian grandmother trying to change her temperament (“Better late than never!” she says)—as well as those working to engineer change: psychologists, neuroscientists, name-change specialists, even his own father, a breath and meditation teacher who once wrote a newsletter about “the art and science of transformation.” Intertwined with those portraits of change is the author’s own reckoning—by turns painful, poignant, and hilarious—with his misfires and epiphanies.

You’ve Changed is a book for anyone who’s ever tried to become someone new, fix what felt broken, drag someone else into changing, or wondered whether real transformation is anything more than a myth we sell ourselves. Denizet-Lewis shows us that profound, positive change is possible—and offers an unexpected, sometimes counterintuitive set of approaches to help us get there. But this is no compass for the dogmatic or the quick-fix brigade. Change, he shows us, is slippery, scary, beautiful, often politically fraught—and best tackled with humility riding shotgun, holding the map upside down.
