In a time before history, Storm and her people lived in the shadow of the menhir, a mystic portal through which humans could commune with the immortal beings of the Godworld. Promised in marriage to a man she has never met, she is honor-bound to secure an alliance that will bring peace and prosperity to her people while obtaining the gods' blessing. But her brief moment of happiness is cut short by tragedy, and the dark god Basra is forced to strike an unholy alliance of his own. Melding human and god, he infuses her with the power of the night in order to save her life, turning her into the world's first immortal.

As Storm sets out to discover the limits of her power and her new life's purpose, the shockwaves of Basra's actions threaten to tear apart the carefully ordered laws of the Godworld. Fettered by millennia of isolation, they will discover limitless possibility and untold power in a world all but ignored: the world of humanity.
