Isabella and her friends are nervous about the New City. It's inland and it's dry--far from the flooded city they've left. Will their lives here be as luxurious and carefree as Xavier says? In fact, bleak, uncertain times have brought darkness and danger to New City. The city is divided in two: the citizens who have, and those who the ruling Major General says have come to steal from them--the refugees who have fled the rising waters, imprisoned in a camp on the edge of the city. The kids of Grimsdon once faced sea monsters and evil harbor lords, but now face new threats. From freakish weather events to the fierce misinformation that swirls around the city to the theft of their freedom, now they face the prison-like restrictions and control of the New City. Unlike the refugees, they're heralded as heroes. But what does the Major General really want from them?
