Kael Hammerson works at a research lab in Ireland. He knows that Ireland is a strange place for a herpetologist to work, but he's running from an abusive relationship and Ireland is the fartherest away he could get. It's been a year since he left his ex-partner and his heart is ready to heal. Hugh Price is interested in Kael, but he's not sure if being Kael's boss will hamper any budding relationship between them. One day, a strange sea creature is brought to Hugh's attention and he knows Kael's the only one who might be able to figure the origin of the specimen. Dragons have returned to the mortal world, but Gaia, the earth mother, needs Kael and Hugh's help to keep the creatures from making humans extinct.
