For thousands of years, Astraea has lived among humans, hiding the truth of what she is and trying to forget the kingdom she lost beneath the sea. Then the dreams begin. A voice calls to her from somewhere she cannot reach. A man she does not remember waits on the other side of a forgotten past. And as her sister’s wedding brings her back to the Aegean, the magic inside her starts to awaken. Deep beneath the ocean, Prince Kaerys is haunted by the same impossible connection. He has a future waiting for him, a woman he loves, and a kingdom depending on him—but every dream pulls him closer to a stranger who feels anything but unfamiliar. As buried memories rise and ancient secrets unravel, Astraea and Kaerys are drawn toward a truth someone went to great lengths to erase. Atlantis may have fallen. But the sea never forgot them.
