Discovering she can hear and manipulate the frequencies where spirits communicate, Dora is thrust into a hidden war for the city's soul. Ancient gods, colonial saints, and favela spirits battle for dominance while a ruthless corporation weaponizes spiritual silence to erase communities. When her brother becomes possessed by warring entities, Dora must master her abilities and choose Rio's future. Can she create harmony between conflicting mythologies, or will the voices of the marginalized be permanently silenced? A supernatural thriller where gentrification becomes spiritual warfare and one woman's gift for listening could save—or destroy—everything.
