'In this important book, Malcolm James offers us a richly drawn account of contemporary youth identities and cultures in superdiverse urban spaces. Based on three years ethnography in East London, his provocative analysis places emergent youth expression and cultural politics in a broader context of historical marginality, social inequality and ethnic diversification. The book provides a compelling portrait of the fusions and fissures of contemporary urban multicultures and political agency amongst a group most often overlooked, both by the academy and wider society. James' work is a compassionate and powerful exploration of these hidden lives.'-Claire Alexander, University of Manchester, UK.
