The Sixth Doctor and new companion Constance Clarke encounter the Doctor's old enemy the Rani - who has some problems of her own: Miasimia Goria was a quiet planet, an ancient world of bucolic tranquillity...until the Rani arrived with ideas of her own. She planned to create a race of new gods...gods that she could keep on her leash, but those plans went horribly wrong. Now, she languishes in the high security of Teccaurora Penitentiary, consigned there by her arch enemy and old student colleague, the Doctor. But the Rani, always resourceful, ever calculating, knows things about the Doctor's past that he would rather forget. She wants revenge, even if it takes a hundred years...and then she has other unfinished business. The ruins of Miasimia Goria await...This is the first of a new run of stories with Colin Baker as the Doctor, a role he's been playing for Big Finish since 1999.
