In a future where memories are sold, stolen, and traded like currency, an emotionally numb woman named Aera works as an Echo Collector—a rare profession responsible for locating and extracting the lingering emotional “echoes” of the dead from the places they loved. These echoes are used by the government to study human behavior and control populations.But when Aera collects an echo that talks back, she discovers it belongs to someone who isn’t dead—someone who was erased. The echo contains secrets that could unravel society’s illusion of freedom and rewrite the understanding of death, memory, and identity.Now hunted by those who built the memory-market world, Aera must decide if she’ll risk becoming a forgotten echo herself to expose the truth—or let silence reign forever.
