"It's me, daddy. It's Bernice."

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.

But what is Benny's father doing five hundred years in his own past? And why has he been waiting for the Doctor to arrive? Can Benny really trust the man she's been looking for all her life?
