Lightning in the Frozen Sky
A year has passed since the Fourth Great Ninja War, and Kakashi's appointment as Hokage looms. But first he heads to the Land of Waves for a dangerous mission rescuing hostages from a top-secret airship. There he confronts a ninja whose heart is frozen by tragedy.
Having lost both his friend's eye and his greatest abilities, can Kakashi protect anyone from his cold-hearted foe? What is the true meaning of the Will of Fire gained in the distant heavens? Kakashi finds these answers and more as he enters a new ninja era.
