Bernice Summerfield was seven years old when her father disappeared. They said he turned and ran from the Daleks in battle. They said he was a coward. They were wrong. For years Benny has searched for her father. Now a clue snatches her from her honeymoon, back to the TARDIS, and on to England in the year 1983. There she at last discovers Admiral Isaac Summerfield, leading a motley crew of aliens, psychics and fanboys. Their mission: to save extra-terrestrials stranded on Earth.
