Divine Rivals. Book 1 (Letters of Enchantment)

When two young rival journalists find love through a magical connection, they must face the depths of hell, in a war among gods, to seal their fate forever.
After centuries of sleep, the gods are warring again. But eighteen-year-old Iris Winnow just wants to hold her family together. Her mother is suffering from addiction and her brother is missing from the front lines. Her best bet is to win the columnist promotion at the Oath Gazette.
To combat her worries, Iris writes letters to her brother and slips them beneath her wardrobe door, where they vanish—into the hands of Roman Kitt, her cold and handsome rival at the paper. When he anonymously writes Iris back, the two of them forge a connection that will follow Iris all the way to the front lines of battle: for her brother, the fate of mankind, and love.
Shadow and Bone meets Lore in Rebecca Ross's Divine Rivals, an epic enemies-to-lovers fantasy novel filled with hope and heartbreak, and the unparalleled power of love.
