The complete omnibus of the ten-part novella serialisation AERA: The Return of the Ancient Gods, from the internationally bestselling author of The Dwarves. The gods are back, the world is in uproar - and only one man has the strength to seek the truth. I've never believed in any kind of god. But that's a problem when they start manifesting. It was a problem for everyone else too, especially those whose gods did not appear. We are divided, a fractured globe, because you'd start to question everything you'd believed, wouldn't you? Or would you fight? Because I don't think these really are the gods we've worshipped. Zeus, The Morrigan, Thor - they can go to hell. We're in the middle of an invasion, and I'm the only one who believes in that reality. My name is Malleus Bourreau. I'm an atheist and an investigator - and I will find the answers.
