Book One

Fourteen-year-old Luce has had a tough life, but she reaches the depths of despair when she is assaulted and left on the cliffs outside of a grim, gray Alaskan fishing village. She expects to die when she tumbles into the icy waves below, but instead undergoes an astonishing transformation and becomes a mermaid. A tribe of mermaids finds Luce and welcomes her in—all of them, like her, lost girls who surrendered their humanity in the darkest moments of their lives. Luce is thrilled with her new life until she discovers the catch: the mermaids feel an uncontrollable desire to drown seafarers, using their enchanted voices to lure ships into the rocks. Luce possesses an extraordinary singing talent, which makes her important to the tribe—she may even have a shot at becoming their queen. However, her struggle to retain her humanity puts her at odds with her new friends. Will Luce be pressured into committing mass murder?

Book Two

After parting ways with her troubled mermaid tribe, Luce just wants to live peacefully on her own. But her tranquility doesn’t last long: she receives news that the tribe is on the verge of collapse and desperately needs her leadership. The tribe’s cruel queen wants Luce dead. Dorian, the boy Luce broke mermaid law to save, is determined to make her pay for her part in the murder of his family. And while the mermaids cling to the idea that humans never suspect their existence, there are suddenly ominous signs to the contrary.

But when Luce and Dorian meet, they start to wonder if love can overpower the hatred they know they should feel for each other. Can Luce fulfill her rightful role as queen of the mermaids without sacrificing her forbidden romance with Dorian?


Book Three

Mermaids have been sinking ships and drowning humans for centuries, and now the government is determined to put an end to the mermaid problem—by slaughtering all of them. Luce, a mermaid with exceptionally threatening abilities, becomes their number-one target, hunted as she flees down the coast toward San Francisco.

There she finds hundreds of mermaids living in exile under the docks of the bay. These are the Twice Lost: once-human girls lost first when a trauma turned them into mermaids, and lost a second time when they broke mermaid law and were rejected by their tribes. Luce is stunned when they elect her as their leader. But she won’t be their queen. She’ll be their general. And they will become the Twice Lost Army—because this is war.
