Letters of Enchantment is Rebecca Ross’s newest duology, which began in April of 2023 with the release of Divine Rivals and concludes in December 2023 with the release of Ruthless Vows. The Letters of Enchantment series is a historical high fantasy set in a world with five sleeping gods intent on war.

Divine Rivals follows Iris Winnow and Roman Kitt. Initially nothing more than rivals at work, they soon become mystery pen pals via their rare, enchanted typewriters and later become war correspondents in west Cambria. Cambria is at war following the awakening of two enemy gods: the Skyward Enva and the Underling Dacre. Iris seeks her brother, Forest, who is one of the soldiers missing from the front. As Iris develops a romance with Roman—who eventually reveals himself as her mystery pen pal, Carver—and finds a found family among the citizens of Avalon Bluff, the war crawls further east. Forest locates Iris in Avalon Bluff shortly after her wedding to Roman, ultimately saving her from Dacre’s encroaching forces by fleeing to their old home in Oath. However, Forest forces Iris to desert an injured Roman with the enemy.

Ruthless Vows continues where Divine Rivals leaves off.
