Ella Pickering is drowning in debt. Once a Unity skymage trained to make aerial supply runs in the great war with the Ranneas Empire, following a crash she now uses a wheelchair and works gruelling shifts making magical weapons in the Unity workshops, thinking of better days.One night Ella witnesses an experiment by engineer Jackan Grissom go awry. His device morphs into a crude rocket blasting skywards before falling into the war's spell-ravaged No Man's Land. But this inspires a dangerous dream: could such a device reach the moon - the forbidden home of the gods? Could they go and beg them to stop the war?They will need help, but as more folk get involved in their blasphemous plot, can they keep it under wraps? Can magic get them to the moon? Or will their heresy lead them to the gallows?
