This chilling and bizarre story is a mash-up of the world of Batman and classic cosmic-horror fiction. Returning from a decades-long voyage of discovery, Bruce Wayne returns to Gotham City, where his parents fell victim to the knife of a madman 20 years earlier. On his journey, Bruce has taken on an international trio of orphaned street kids – Batman fans will recognise as various iterations of Robin. During a deadly Arctic encounter, Bruce learns that a doomsday cult is planning Gotham’s destruction. Bruce must now return home and take on the mantle of Batman. But when this man of science discovers he faces not criminals and crazies but actual ancient magic, fiery demons and interdimensional Old Gods, can he retain his sanity?
