The first manned expedition beyond our solar system leads to a deadly encounter... Lieutenant Dane Clark, second-in-command of Trailblazer One, is flying with over 300 colonists on a historic voyage to Proxima Centauri b, humanity's first step toward establishing a new home among the stars. But their arrival reveals a chilling mystery—a strange signal is pulsing from the planet's surface, luring them in. When a crew descends to investigate, what they uncover is beyond comprehension—and beyond escape. Isolated over four light-years from Earth, the crew must decide whether to establish a colony on this alien world or turn around and run back to Earth.
