A compelling examination of the contemporary art of self-transformation, from the New York Times bestselling author

As obsessed as we are with change, we're also often wildly suspicious of those who claim to have pulled it off.

In You've Changed, Benoit Denizet-Lewis shows how so much of what we think we know about self-transformation is wrong. Profound change is often less self-reinvention than self-discovery, and personal change isn't always so personal — it's better understood as a hazardous team sport.

Drawing on insights from psychologists, neuroscientists and spiritual teachers, Denizet-Lewis confronts our ambivalent relationship with change by taking us inside the lives of people who've transformed themselves — or say they have. From psychedelic reality benders to political converters, from a seemingly transformed murderer to a bully-turned-Buddhist, Denizet-Lewis brings curiosity, empathy and humour to this compelling investigation of the many ways we try to reimagine ourselves — and what's at stake when we do.

You've Changed challenges us to think more deeply about how real transformation happens and is essential reading for anyone who's ever wanted to change something meaningful about themselves, or someone they love.
