Be twice as good as men and four times as good as white men.

Jia Khan has always lived like this. Successful London lawyer Jia Khan is a long way from the grubby Northern streets she knew as a child, where her father, Akbar Khan, led 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. Now, with her father murdered, Jia must return to take his place. The police have always relied on the Khan to maintain the fragile order of the streets.

But a bloody power struggle has broken out among warring communities and nobody is safe. Justice needs to be restored, and Jia is about to discover that justice always comes at a cost.
