After Miigaadiwin

"After the Immortal invasion, they take over every nation on earth and set themselves up as rulers without any accountability! I'd call that a pretty successful invasion," Tom summed up.
Gizhaa was shaking his head involuntarily, but all he said was, "I've never heard this before."

Nearly a thousand years after Earth has recovered from a catastrophic war, the conquering Immortals rule the world, demanding annual tribute in exchange for prospering rains. But not everyone is happy with the system. When siblings Gizhaa and Inaa accompany their father on a historic diplomatic journey to the capital, they find themselves at the centre of a plot to restore an ancient government.
Someone doesn't want their journey to succeed, however, and they are soon entwined in political espionage. They must decide if they will help to overthrow the Immortals or trust their own gifts, which warn them of great danger ahead.
When it seems Inaa's heart is compromised, leading her into a reckless relationship, Gizhaa wonders if he will lose her. But how much will it cost him… and the world?
