The world has been noticed.Nothing will ever feel the same again.The signal has been sent.No answer follows.As Earth continues to react, escalate, and adapt, the city remains-open, present, and silent. The decision has already been made, but its meaning has not yet arrived.Inside the city, its inhabitants confront the final consequence of restraint: when prediction collapses, delay becomes action. Silence becomes isolation. Contact becomes evaluation. Neither choice can be undone.Beyond Earth, something listens.Or perhaps it simply records.The Closed City: Legacy is the powerful conclusion to The Closed City Series-a high-concept science fiction thriller about responsibility, irreversibility, and what it means to be seen without being answered.There is no invasion.There is no rescue.Only the long view-and the weight of what humanity has become.Book 4 of The Closed City Series.
