Cosmos is a 'monthly magazine, produced by Luna Media Pty Ltd, a specialist publishing house in Sydney, Australia.' The magazine's focus is on developments in science and it includes a regular contribution from science-fiction authors.
'Attorney Jill Shannon's clients include Blick Pharmaceuticals, which is pursuing research into life-extending drugs. Blick has reawakened the homicidal maniac Payback, whom they created twenty years earlier, to literally kill off the competition by targeting research scientists. Jill's boyfriend, Paul Gibson, one of the scientists, is forced to inject them with an intelligence booster. Suddenly they find themselves in the middle of a war--a war over what it means to be human (and more than human). Can any of them survive?'
