Divine Rivals

Eighteen-year-old Iris dreams that one day her writing will make a difference. A war between gods is raging, and she’s landed a prestigious job at the Oath Gazette.

But at home, she’s barely holding it together. Her brother is missing on the frontline. Her mother is lost in a haze of addiction. And each night Iris pours her heart out in letters to her brother.

Letters that will never be answered. Or so she thinks…

Her letters have made their way into the hands of the last person Iris trusts: Roman Kitt, her cold, unforgiving rival at the paper. When he anonymously writes back, they forge a magical connection that will seal their fate forever.
