SYNOPSIS:

In the mermaid kingdom of Ouceanus, travel between dimensions is tightly controlled. Citizens must apply, justify their reason, and get official approval even the royal family must follow the rules. Princess Catharina, quiet and disciplined, has never had the freedom to explore beyond her world. Until one morning. She wakes up to a torn note pinned to her bed: A coordinate. A drawing of a strange lake. And two words: Find me. She rushes to the royal portal… but it’s gone. The stolen portal is now hidden inside Ame’s magical black-market shop. Ame and Amy stole it because it allows them to trade across dimensions without being monitored. When Catharina discovers the truth, she doesn’t expose them. Instead, she makes a secret deal: They keep the portal. She uses it whenever she wants. Nobody tells the kingdom. Now she must decode the full coordinate, she only has 3 numbers out of 6. With 999 combinations left, she begins jumping across dangerous dimensions, searching for someone she has never seen and does not recognize. Meanwhile, she is unaware of the secrets behind her own bloodline. Unaware that her “aunt” Rovana is an impostor. Unaware that her true aunt, Vivia, is alive but trapped. Unaware that half-blood mermaids like Ame, Vivia, and even the queen are illegal, dying without the rare flower that only grows in the dimension Vivia is locked in. And Catharina herself… is not the pure mermaid princess she believes. Every jump brings her closer to uncovering the truth about the message, the portal, the kingdom’s lies, and her own identity.
