The conflict between the summer-lovers and winter-lovers persists to this day, but it never occurred to anyone-or rather, to the inhabitants of this mortal world-that these seasons hold such weight and that kingdoms are governed within them. The only one aware of this was Harry Dresden, whose destiny led him to resolve what is undoubtedly the most powerful conflict on Earth. It seems that the kingdoms of summer and winter are on the verge of igniting a war, and if this happens, it will have two consequences: either infernal heat or deadly cold. But the certain outcome is the annihilation of humankind, or as it is called in the underworld, the mortal world! This time, Harry is doomed, and he awaits his death with equanimity.
