This chapter posits that water’s repudiation of containment transforms this element into a space, place, and being that can usher in new directions for Latinx studies. Specifically, the chapter contends that when water overflows it “undoes” the work of borders, a move signaled by the Spanish word for this action, desbordar. Underscoring how water can generate theoretical frameworks that reach across geographic divides, the chapter provides a succinct analysis of this element in Héctor Tobar’s The Tattooed Soldier, Myriam J. A. Chancy’s What Storm, What Thunder, and Daniel José Older’s Shadowshaper. The chapter also stresses the connections between environmentalism and spirituality by emphasizing readings of water informed by Afro-diasporic religions such as Haitian Vodou and Santería/Regla de Ocha. By highlighting water’s capacity to sustain conversations regarding such topics as violence, memory, and repair, the chapter offers water as an entryway into critical conversations in Latinx literature that do not disregard cultural and/or national specificity but remain provocatively untethered to these allegiances.
