Roots in the Waters is a work of historical narrative nonfiction that reconstructs family and migratory trajectories between Europe and the Río de la Plata from the late nineteenth to the twentieth century. Drawing on archival research, civil and parish records, family memory, and historical context, the book follows lives marked by departure, labour, loss, settlement, and the search for identity across generations. Centered especially on Croatian and Galician roots, the work explores migration not only as a physical journey across the ocean, but also as a lasting emotional, cultural, and historical legacy.
