Stargate Atlantis: Earth and Sky

AU from Enemy At The Gate. Returning to Pegasus was never going to be easy. With the Wraith still a threat in that galaxy, Homeworld Defense in disarray from the battle, and Atlantis in need of major repairs, is leaving even possible? Or is Earth once again it's home? And what of the aliens that call the city home? Will life and love find a way? Rating subject to change later on.
