"This is a book that genuinely moves us forward. It is reassuring and encouraging to see a collaborative group of researchers reframe the challenges and potentials of creating age-friendly urban places by reimagining them through the critical lenses of diversity, equity, and co-production. To accomplish this in a way that moves us toward social and spatial justice and counteracts the currently pervasive trend in the opposite direction is fitting testimony to the pioneering contributions of Chris Phillipson to whom the volume is dedicated."
