The Goddess Of by Randi Garner

No gods or curses will keep them from each other.

Naia, the daughter of the High Sea Goddess, is an embarrassment. She holds no title and no power but is the key to a curse placed centuries ago on her mother: Naia must form a union with a god from an opposing family.
When the day arrives for her arranged marriage, she turns to the High God of Death and Curses for help.
He assists Naia under one condition—she must accept a curse, blindly. Willing to do whatever it takes to escape her mother’s kingdom beneath the sea, Naia agrees and flees to the Mortal Land.
When she wakes up in Ronin Kahale’s childhood home, she’s greeted by the warm, welcoming twenty-eight-year-old mortal. Distrustful of Ronin and his selfless hospitality, she’s convinced there’s more to him than what he’s sharing.
However, he’s her one-way ticket into Hollow City, an ominous concrete jungle infested with witches. Somewhere among its streets lies Finnian, Naia’s younger brother and the only one capable of helping her hide from their cruel mother.
Naia desperately tries not to care for another mortal, but as her life intertwines with Ronin’s, she questions the lengths she will go to keep him safe from the gods who hunt her down—and the curse that looms over her.

With gods, though, everything comes with a price.
