- Mark/Mary Reed, an American woman who defies stereotypes by dressing as a man.
Mutiny ensues against the tyrannical Captain Skinner, who is thrown overboard to make way for democracy aboard The Night Rambler. The crew's new order provides radical social benefits, all based on real, documented practices of contemporary pirate ships: democratic decision-making, a social security net, health and disability insurance, and equal distribution of spoils taken from prize ships. It's not long before the London elites enlist a war-hungry captain to take down The Night Rambler and start a war of high society versus high-seas pirates. Adapted from the scholarship and research of historian Marcus Rediker, Under the Banner of King Death will inspire readers with its tale of those on the bottom fighting back and achieving, against all odds, a democratic and egalitarian social order, if only for a short time.
