The Interstellar Initiative didn't have an easy start. Tensions between species complicated even the simplest tasks, not to mention the perils created by an unstable extra-dimensional entity named Wallace.Then, just as the alliance figures out how to work together effectively, Humanity's first interstellar sins come back to haunt them. What first appears to be an extra star in Earth's night sky is-something else-and it's ready to rain destruction on the planet if the Initiative doesn't figure out how to communicate or counter it.The best hope of saving humanity may once again rest in the hands of four cadets and the starship Endeavor.
