A shy girl must become a true heroine to save her city and win the heart of her Divine Guardsman.
Nothing in Tia's quiet, humble life has prepared her for the day a member of the Divine Guard of Poseidon appears at her door and throws down a challenge: will she compete for the honor of becoming a Dreamer in the great Temple of Poseidon? She agrees, little suspecting that an even greater challenge lies ahead, one that will test her to her limits and beyond.
