Waterfire Saga

Deep in the ocean, in a world not so different from our own, live the merpeople. Their communities are spread throughout the oceans, seas, and freshwaters all over the globe. When Serafina, a mermaid of the Mediterranean Sea, awakens on the morning of her betrothal, her biggest worry should be winning the love of handsome Prince Mahdi. And yet Sera finds herself haunted by strange dreams that foretell the return of an ancient evil. Her dark premonitions are confirmed when an assassin's arrow poisons Sera's mother.

Serafina, Neela, Ling, Ava, Becca, and Astrid, six mermaids from realms scattered throughout the seas and freshwaters, were summoned by the leader of the river witches to learn an incredible truth: The mermaids are direct descendants of the Six Who Ruled - powerful mages who once governed the lost empire of Atlantis. The ancient evil that destroyed Atlantis is stirring again, and only the mermaids can defeat it. To do so, they need to find magical talismans that belonged to the Six.

Once a lost and confused princess, Serafina is now a confident leader of the Black Fin Resistance (BFR). While she works on sabotaging her enemy and enlisting allies for battle, her friends face challenges of their own. Ling is in the hold of Rafe Mfeme's giant trawler, on her way to a prison camp. Becca meets up with Astrid and learns why the Ondalinian mermaid is always so angry: She is hiding a shameful secret.

Orfeo possesses one of the six talismans that the merls need in order to keep the monster locked up forever. But without the ability to songcast, how will Astrid be able to defeat the most powerful mage in history? Meanwhile, Serafina and her Black Fins train goblin troops for battle against her uncle Vallerio's death riders. Will Sera ever see her beloved home - and her beloved Mahdi - again, or will the Volneros take over the mer realms while Orfeo takes on the gods themselves? Nothing less than the fate of the underwater world is at stake in this breathtaking finale.
