As the last remaining water goddess, Lorelei is forced to save her best friend from the all-powerful Guardian King by reuniting with the only woman who has ever been able to capture her heart. She finds herself falling the moment she sees the powerful charmer, Ash, whose ability to manifest Lorelei's every desire consumes her body and mind, strengthening Lor's abilities as one of the most powerful beings in the world. Ash doesn't expect the love of her life to return to her decades after their first relationship, but when Lorelei seeks her out again, she finds herself lost in the beautiful, fiercely independent woman who has lingered in her mind and her heart since they parted. Together, they must forge a dangerous physical and emotional bond that will strengthen them both for the effort to defeat the king, and to save humanity from his ruthless invasion.
