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.
