[4] Grace Blakely is a sixteen-year-old American who grew up between her native country and the fictional Mediterranean nation of Adria, located in the Balkan Peninsula, which she has roots in.

Grace remembers the face of a man with a large scar who was on the scene of Caroline's death, and believes he was responsible for the murder.

They immediately become friends and Grace sticks up for Rosie when Noah's twin sister, Lila, bullies her and demands that she leaves.

In a fit of anger, Rosie snatches Lila's scarf, but the wind blows it out of her hands and lands on the Iranian flagpole.

Grace realises that the scarf bears a striking resemblance to the Israeli flag and Noah immediately calls off the party, scared to cause an international incident.

Despite protests from her friends, later that night Grace breaks into the abandoned Iranian embassy to retrieve the scarf but overhears two men meeting in secret.

At the G20 summit, which is due to be held in Adria, she believes that someone is going to assassinate the Prime Minister, but learns instead that Dominic was actually a friend of her mother's.

Dominic tries to persuade Grace to run away, but Ms Chancellor shoots the Prime Minister in the chest, sending him into a coma.
