Atana may be one step closer to discovering her past, but it didn't come without a cost. Though the mermaid and her companions-Ren, the last known firebird, and Cosmos, her witch guard-turned-friend-narrowly escaped the Witch Queen, time is running short. They may have foiled the Queen's plans to use Ren to revive their world's broken magic cycle, but Ren is still growing weaker by the minute Atana and Cosmos are determined to help their friend recover, but Ren's priorities are elsewhere. After discovering that the firebirds of old are responsible for destroying the flow of magic for all beings, she is determined to right her people's wrongs. When Atana resolves to join this quest, her past-lurking deep below the seas-threatens to destroy not only their friendship but also their very chance at restoring the balance of magic itself. After a lifetime of dreaming of finding a home below the water, is Atana willing to leave behind everything she's fought for on land?
