Bonded by power forged in lust

Kael is nothing more than a common slave until he stumbles across a goddess that has been locked away and stripped of her power by the all-powerful dragon that controls the continent he lives on. When Kael agrees to use his "weapon" to become her champion, he must break free of his own chains so he can restore her to her former glory. Will he succeed or be crushed under the might of the ruler and his enforcers throughout the continent?
