The cyber underworld of radicals and hackers collides with international power politics in the new novel from twice Man Booker Prize winner Peter Carey. Has a young Australian woman declared cyber war on the United States? (The Justice Department thinks so.) Or was her Angel Worm intended only to open the prison doors of those unfortunates detained by Australia's harsh immigration policies? Did America suffer collateral damage? Can she be extradited to a country with the death penalty? Is she innocent? Can she be saved?
