Contemporary culture tells us the twenty-something years don't matter. Clinical psychologist Dr Meg Jay argues that this could not be further from the truth. 

The Defining Decade weaves the latest science of the twenty-something years with real-life stories to show us how work, relationships, identity and even the brain can change more during this decade than at any other time in adulthood.

Smart, compassionate and constructive, The Defining Decade is a practical guide to making the most of the years we cannot afford to miss. Included in this updated edition:

• Up-to-date research on work, love, the brain, friendship and technology
• What a decade of device use has taught us about looking at friends - and looking for love - online
• A social experiment in which 'digital natives' go without their phones
• A reader's guide for book clubs, classrooms or further self-reflection
