A Monsoon Rising

Why these tropes fit

A politically arranged marriage between two sworn enemies from rival nations—the Shadowforged Legion's master and a Lightweaver empress—forces them into close quarters where rivalry steadily thaws into romance. As court conspirators plot to overthrow the new husband, the heroine plays a careful double game while a prophesied cataclysmic event can only be halted by the unique merging of their opposing powers, pulling the couple ever closer even as divided loyalties and a sinister father-in-law threaten everything.
