'Sam's boundless resourcefulness brings together an unusual resistance team of blacksmiths, retired academic, security guard and managing director of a former cutting-edge tech company. Despite winning many skirmishes, Sam's forces face defeat. Their only chance of survival is to drive their campaign into the aliens' covert stronghold. But the last time this was attempted it ended in disaster. Will they make it out alive this time?

'Covert Citadel is the second of a series of novels set in near future outback Australia, where pandemic contagion has wiped out 80% of the population and wrecked the economy.'
