When the king of Atlantis dies, the citizens look to their former ruler Aquaman for leadership. But the undersea civilization that he and Dolphin return to is falling apart. The people are fleeing the capital city of Poseidonis as mysterious forces lift it ever closer to the surface. Aquaman must undo the damage or else the environmental impact of the rising city could be catastrophic—not only for Atlantis, but for the surface world as well! Plus, the much anticipated return of Mera, Aquaman’s long estranged wife. But what will she make of her husband’s new relationship with Dolphin? Peter David’s character defining run continues in these stories from Aquaman #9-20 and Annual #1! With art from Martin Egeland, J. Califiore and more, these tales also feature guest-appearances from Justice Leaguers Green Lantern, Superman and Wonder Woman!
