Is Hard Sun coming back?

Set in contemporary London, Hard Sun centers on detectives Robert Hicks and Elaine Renko, partners and enemies who seek to enforce the law and protect their loved ones in a world that every day slips closer to certain destruction. Hicks is a family man and a great, committed officer. He's also profoundly corrupt. Renko is a difficult and damaged, but utterly incorruptible officer. Thus, the two cops stand on different ends of the social and moral spectrum and also seriously distrust one other – and for good reason. But they must somehow learn to work together if they're going to survive until the end of the world.
