A subway ride home becomes a journey into the greatest moment in human history.
Elena Reyes is exhausted, disappointed, and trapped in a life of corporate spreadsheets, far from the meaningful work she once dreamed of. Then a mysterious subway porter hands her an old brass token marked 4488, and everything changes.
One moment, Elena is riding the New York City subway. The next, she steps into the humid streets of Houston, Texas, in July 1969. Apollo 11 is about to launch. It's 1969, and everyone believes Elena is Dr. Elena Reyes, a missing NASA telemetry expert whose work may be critical to the moon mission. As Elena struggles to survive in a life that is not her own, she discovers a hidden anomaly in the Apollo data. It's a signal that appears only when a spacecraft approaches the moon.
At first, it looks like random noise. Then it begins to change. As the launch countdown ticks and three astronauts prepare to make history, Elena must uncover the truth behind the signal before Apollo 11 reaches Tranquility Base on the moon. Something is waiting out there on the moon. Humanity's first giant leap may lead to a discovery no one on Earth is ready to face.
