The young explorer Captain Naomi Turner returns back to the Kingdom of Avalor, where everything has changed and everyone had grown out the people they once were. Well, every one except the Chancellor of Avalor and cousin to Queen Elena, Esteban Flores, much to Naomi's chagrin.
However, when the two of them go in place of the pregnant Elena to respond to a distressing call in Norberg, they find that good Queen Abagail is dead, Chloe is missing, and an imposter and his slimy advisor having taken to the Throne. To top it off, this Phony King demands the capture and questioning of Naomi as a possibly conspiring Norbergian. To avoid this, Naomi must go from being a Norbergian to an Avaloran. They only solution: Marriage. To Esteban.
While this solution is effective, it's the last thing Naomi and Esteban ever wanted. But, they'll have to learn to rely on one another as they hope to find Chloe, face the demons of the past, new dangers that threaten the future, and Naomi learns that Royal Court is a much more dangerous game than Pretty dresses and airheaded Royals. Especially when a slow burning attraction begins to arise and complicate matters even more.
This story takes place not long after Elena becomes Queen of Avalor. Elena, Isa and their friends (including Sofia, Amber and James) travel to Freezenburg to form an alliance with Crowned Princess Hildegard (who became Crowned Princess when her sister Astrid gave up her claim to the throne). Along the way; the friends learn that the King and Queen of Enchancia never returned to their kingdom, and that they were lost at sea. Amber learns that she's now officially Queen of Enchancia and must return home for her immediate Coronation, as they received word that Amber is now officially Queen of Enchancia; they are visiting the Black and White island prison of Queen Ivy, which has grown and flourished since Sofia last visited. And they will discover that a threat looms in the future that will cause an Interdimensional Conflict and they must align themselves with a faction called the United Republics of Earth to fight against the threat. Will they succeed in uncovering and defeating this threat or will the whole EverRealm be thrust into an all-out war against the threat from Earth? Read on to find out.
