<p>No alien civilizations. No signs of extraterrestrial life. Just endless void and the lingering question: <i>are we truly alone?</i></p>
<p>Dr. Elena Vasquez, a brilliant but disillusioned xenolinguist stationed on the remote deep-space listening post Kepler-9, has spent fifteen years monitoring the cosmic static. When an impossible signal emerges from the darkness—a repeating pattern that defies all known physics—she becomes the first human to confirm what many have feared and others have prayed for: <b>we are not alone.</b></p>
<p>But the signal is not a greeting. <b>It is a warning.</b></p>
<p>As Elena races to decode the message, she uncovers a conspiracy that stretches from the corridors of Earth's United Space Command to the furthest reaches of colonized space. Someone knew about the signal decades ago. Someone tried to bury it. And now, with the decoded message pointing to an imminent cosmic event that could reshape human civilization, Elena must decide who to trust—and whether humanity is ready for the truth.</p>
<p><i>The Last Signal</i> is a gripping science fiction thriller that explores the nature of communication, the weight of first contact, and the terrifying possibility that some messages are meant to be heard—but never answered.</p>
<p><b>Perfect for fans of:</b> <i>Contact</i> by Carl Sagan, <i>The Three-Body Problem</i> by Liu Cixin, and <i>Project Hail Mary</i> by Andy Weir.</p>
