O Tempo Em Marte by Philip K. Dick

On a drought-scarred Martian colony, a troubled worker struggling with mental illness becomes entangled with a settler family and an autistic boy whose atypical perception of time reveals unsettling truths; as corporate land grabs, water scarcity, and communal prejudice escalate, shifting perceptions of reality and causality force characters to confront responsibility, exploitation, and the fragile boundary between sanity and delusion.
