Warrior-mage partners Toria Connor and Kane Nalamas have reached the pinnacle of their mercenary career, known far and wide and offered their pick of jobs. Mixing business with friendship, they accept a long-term contract across the ocean in Londinium, even though it means a six-month separation from their loved ones in Limani.
