Based on Deep Blue by Jennifer Donnelly journey with Serafina on the adventure to save the mer realms, but with some twists. What if Astrid was friends with Serafina from the start. What if a human meets Serafina(besides Mfeme and others). What if Mahdi wasn't Serafina's love. What if Isabella survived. Serafina, daughter of Regina(queen) Isabella is part of a prophecy. She and five others must defeat Abbadon and save the mer realms before it's too late. They must find talismans to defeat him, but it won't be easy because somebody else is looking for the talismans too. (I do not own characters except for Carlos and Rachel because I made them up. The others are from the book. Also pictures come from google and the website of waterfire saga)
