Maya Elliott hasn't heard her mother's voice in two years. Lewy body dementia has locked Rachel Bose's mind from the inside out, causing hallucinations and language loss. When Maya discovers her mother's memoir, she sees it as a chance to hear her voice again, if only within its pages. But a long-hidden secret forces Maya to question which version of the past to believe. Catapulted into an evocative journey through her mother's life, Maya must determine where hallucination ends and truth begins-even if it upends everything she knows about her family. The Sand Diamond is a sweeping story of mothers and daughters, entwined destinies, and the secrets that shape us.
