Michael Dobbs returns to the subject that made him a household name - the human drama and scandal in the corridors of power.
Ginny is the young wife of an Opposition MP and is entirely content with her life in the constituency home.
So when she overhears gossip of her husband's affair, it is a shattering blow.
For some women such revelations become part of the Westminster game, but Ginny is no ordinary woman.
She decides that there is only one way to stop being a perpetual victim of the system, and that is to become its master.
Ginny will not be satisfied until she is the wife of the Prime Minister.
