First in a critically acclaimed series by New York Times and USA Today bestselling author Alyssa Day . . .

Eleven thousand years ago, before Atlantis vanished beneath the waves, Poseidon chose seven warriors to protect humanity. One rule bound them all: never fall for a human.

Some rules were meant to be shattered.

Riley Dawson isn't your typical Virginia Beach social worker—she's an empath with a rare psychic gift that hasn't been seen since the time of the Atlanteans. The ocean calls to her with a fierce, aching pull . . . and something—someone—is calling back.

Conlan, High Prince of Atlantis, has risen from the depths on a desperate mission to recover Poseidon's stolen Trident. But when his mind unexpectedly links with Riley's, the connection is immediate, intense—and forbidden. Drawn to her strength, her beauty, and her soul-deep empathy, Conlan finds himself torn between duty and desire.

But in a world of ancient magic and ruthless enemies, can love between a mortal and a warrior of the deep survive the tides of war?

Destiny surfaces. Passion ignites. And Atlantis will never be the same.
