This groundbreaking monograph critically addresses the ocean deficit in postcolonial thinking, positioning the Indian Ocean as a vital space for future theoretical exploration. It illuminates the epistemic configurations of blue postcoloniality while aligning with recent advancements in Blue Humanities scholarship through a rich tapestry of literary works and theoretical frameworks. Challenging conventional perspectives that relegate oceans to morbid repositories of human waste, the author employs Deleuzian frameworks to reexamine shared cultural histories through oceanic perspectives. The work moves from ancient Indic aqua-narratives that reveal the transhistorical nature of oceanity to contemporary South Asian literature—including Sharon Bala's The Boat People and Amitav Ghosh's Gun Island—that foreground the nuanced intersections between human and nonhuman entanglements within Indian Ocean contexts. Through innovative kinopolitical insights, the monograph examines Romesh Gunesekera's Reef to demonstrate how the Indian Ocean becomes a space of resistance and resilience in the face of climate change. The concept of the blue diagram is further explored through Sejal Mehta's Superpowers on the Shore, revealing the metamodeling abilities of the Indian Ocean through layered interactions among matter, energy, and lifeforms. This work questions established understandings within blue humanities while highlighting postcolonial thinking's ocean deficit through Deleuzian perspectives. Unlike existing scholarship, it interrogates blue humanities while strategically realigning it with Deleuzian frameworks to articulate the Indian Ocean's growing significance in shaping the economic, cultural, and political futures of our post-global world.
