The SwarmAudiobook CD - 2016
Bestselling authors Orson Scott Card and Aaron Johnston return with an all-new prequel to "Ender's Game," The Second Formic War. The first invasion of Earth was beaten back by a coalition of corporate and international military forces. Scientists determined that the single ship that wreaked such damage was merely a scout ship. There is a mothership out beyond the Solar System's Kuiper Belt, and it's heading into the system, unstoppable by any weapons that Earth can muster.
