Through deeply personal and culturally grounded narratives, Water Lessons explores the relationship between reality and imagination, faith and doubt, presence and absence, as the speaker grapples with multiple dimensions of grief arising from her mother's alcoholism and eventual death, her father's deepening dementia, and her own childlessness. Against the backdrop of these personal griefs, the speaker scrutinizes the patriarchal underpinnings of the world she grew up in as well as her complicity in systemic racism as a white girl growing up in the 70s and 80s. Woven throughout the book are the speaker's meditations on a divine presence that, for her, is both keenly felt and necessarily elusive, mirroring the speaker's ultimate celebration of her unborn daughter as a "lovely fiction" who is both here and not here.
