Set years after the events of *Ender's Game*, *Speaker for the Dead* follows Andrew "Ender" Wiggin as he travels to the planet Lusitania to investigate the mysterious death of a xenobiologist. As he navigates the complex social and religious dynamics of the colony, Ender must mediate between the humans and the native alien species, the Pequeninos, while grappling with the guilt of his past actions as a military commander. This novel serves as the second installment in the Ender's Saga, shifting the focus from tactical warfare to themes of empathy, communication, and the moral complexities of xenology.
