An emphatic deep dive into the continual movement required of migrants, The Horizon Line studies a relatively recent and little-explored social and migratory phenomenon. For about a decade, the somewhat unprecedented occurrence of double migration has been observed in Italian Bangladeshis engaging in a second move to London. Told through the lens of a fictionalized ethnographer and presented in the form of accessible and captivating comics, this book traces the concept of onward migration and the lives shaped by it. Through interviews with Italian Bangladeshis who made the difficult decision to re-uproot their lives in search of better, social scientists and comic artists Francesco Della Puppa, Francesco Matteuzzi, and Francesco Saresin come together to highlight the joys and struggles of this new (e)migration. The authors offer insights on the dynamism of these "new Italian citizens." and on the migration routes shaped by the continuous global transformations, and on the social, political, and economic situation of Italy and the Southern European countries. Moreover, by following the trajectories of Stefano the researcher, the book provides valuable insight into the modalities, processes, difficulties and turning points of conducting ethnographic research. An essential contribution to migration studies, The Horizon Line gives voice to diasporic communities and sheds light on their most current trials and tribulations.
