In Alura, sirens take part in the Dive; an ancient ritual that places them in one of three tribes; the Azora, the Voeks, or the Draven. Each tribe wields different powers and abilities, some stronger than others. A siren will know which one they join by the color of their hair, for it will change to either, white, gold, or black. For Amaris, the Dive has terrified her ever since she was a youngling. From watching fellow sirens take part and her friend Jessenia, Amaris only sees what the Dive takes away. To her, the Dive strips a siren of their personality and vibrance of life. No matter how much Amaris tries to avoid it she cannot. But unlike her fellow sirens, when Amaris breaks the surface, her hair isn’t the color of any of the three tribes. It’s a shimmering blue. If a siren isn’t placed in one of the three tribes, they no longer have a place in Alura. Amaris quickly finds herself Adrift—-the first siren sent to live amongst the humans in centuries. On the night she is forced to leave, she receives a message from her friend Jessenia, who is part of the Draven, a coven of sirens who have the gift of Seeing. Jessenia tells her that she must seek out the Four Mothers, powerful beings who are part of the Divine. Now, suddenly an outcast, Amaris is forced to start a search she has no clue where to start from. But when an unfortunate encounter leads her to Ford, a warlock and a sirens sworn enemy, Amaris has no choice but to turn to him as a guide. Especially when he reveals he has the information she needs. As Amaris and Ford travel together to gather answers, Amaris begins to question everything she thought to be true. And as they get closer to finding the Mothers, Amaris begins to wonder if she was sent Adrift for her own protection or for the protection of Alura.
