La Jolla, Wildstorm 2005, cm.17x26, pp.96, paperback. High above the planet, aboard a fifty-mile-wide alien vessel, The Authority - seven awesomely powerful super-humans - act as global bouncers for the human race. If you threaten the life and liberty of Earth's inhabitants, they'll do whatever they need to do to set things straight! With the President out to discreetly dispose of them and a seemingly global depression epidemic on their hands, it's only a matter of time before The Authority are forced to react...This stand-alone story is by the brilliant new creative team of acclaimed novelist, screenwriter and journalist John Ridley and up-and-coming artist Ben Oliver.
