Be twice as good as men and four times as good as white men. Jia Khan has always lived like this.

A successful lawyer, her London life is a long way from the grubby Northern streets she knew as a child, where her father headed up the Pakistani community and ran the local organised crime syndicate. Often his Jirga rule—the old way—was violent and bloody, but it was always justice of a kind.

But now her father, Akbar Khan, has been murdered and Jia must return to take his place. In the past, the police relied on him to maintain the fragile order of the streets. But a power struggle has broken out amongst the various communities and now, nobody is safe.

Justice needs to be restored, and Jia is about to discover that justice always comes at a price.
