On a training run 48 light years from Earth, Selene and Charlie encounter an armed vessel packed with insect like aliens, all determined to kill them. Earth's destiny hangs in the balance. However, the world's timelines are tangled. Someone has changed Earth's history for the worse, leaving the planet vulnerable to invasion.
