Divine Rivals delivers a compelling blend of mythology-inspired fantasy and contemporary romance that will particularly appeal to readers who enjoyed Hades and Persephone retellings. Rebecca Ross crafts a world where Iris Winnow, an aspiring journalist, finds herself caught between warring gods while exchanging anonymous letters with her workplace rival, Roman Kitt. The epistolary elements add genuine charm to their relationship development, creating authentic emotional stakes before the inevitable reveal.

Ross excels at building romantic tension through both the letter exchanges and the competitive newsroom dynamic, making the enemies-to-lovers progression feel earned rather than forced. The mythological framework provides solid worldbuilding without overwhelming the character-driven plot, and the war between gods creates genuine stakes beyond the romance.

However, the pacing stumbles in the middle act when the focus shifts heavily toward the divine conflict, temporarily losing the intimate character work that makes the opening so engaging. Some readers may find Iris's family trauma subplot feels underdeveloped compared to the romantic elements, and Roman's character development occasionally takes a backseat to plot advancement.

The writing style is accessible and engaging, though Ross sometimes relies on familiar YA fantasy tropes that may feel predictable to genre veterans. The book works best for readers seeking character-driven fantasy romance with mythological elements, particularly those who enjoy workplace rivals-to-lovers dynamics and epistolary storytelling. Adult fantasy readers looking for complex political intrigue or grimdark elements should look elsewhere, as should those who prefer romance-light fantasy adventures. Young adult and new adult readers who loved books like Lore Olympus or Percy Jackson but want more mature romantic content will find this hits the sweet spot. The cliffhanger ending clearly sets up a sequel, which may frustrate readers seeking standalone satisfaction but will delight those ready to invest in a series.
