This study documents the broader cultural consequences of Indonesian Malay women's work-related mobility on the practice and understanding of what it means to be Malay. In so doing, the book: Provides a rare investigation into the ethnocultural effects of Indonesian women's mobility (i.e, in term of the way women's mobility reconfigures ethnic identifications). Critically addresses the historically-informed assumption that Malay men, through their mobility, are the carriers of Malayness, Islamic reform, and modernity Deepens our appreciation of the significance of gendered forms of mobility across territorial and non-territorial borders to the construction of identity Provides a borderlands perspective on women's independent labour migration in a part of West Kalimantan where studies of women's labour migration remain scarce
