Rivals, not deep enemies
Iris and Roman begin as professional rivals. The tension comes from competition, distance, and connection rather than villain-level hatred.

Read Divine Rivals and Ruthless Vows in order, then understand the Letters of Enchantment duology, its magical letters, and what comes next.
Start with: Divine Rivals
Divine Rivals is Rebecca Ross's lyrical fantasy romance about rival journalists, enchanted letters, war between gods, and a relationship that continues into a complete duology.
No. Divine Rivals is not a standalone; read it first, then Ruthless Vows. Book one sets up Iris and Roman, the letters, and the war; book two resolves the same storyline. The Letters of Enchantment duology is complete, so Ruthless Vows is essential rather than optional. Wild Reverence is a separate adult standalone in the same gods’ world, not Book 3.
Start with Divine Rivals and continue with Ruthless Vows. The two books form one continuous story, so book two is essential rather than optional.

Ruthless Vows
December 2023
Divine Rivals begins the story, and Ruthless Vows completes it. If you want a finished two-book commitment, this is a safe place to start. If you want a true standalone, look elsewhere.
Divine Rivals is a complete two-book fantasy romance built around magical correspondence, wartime pressure, and emotional intimacy.
Iris and Roman begin as professional rivals. The tension comes from competition, distance, and connection rather than villain-level hatred.
The enchanted letters are not just a romance device. They carry the relationship while the war and the gods reshape the world around it.
Ruthless Vows is the direct conclusion. Read it after Divine Rivals for the complete story, not as an optional companion.
Wild Reverence is an adult standalone set in the world of the gods first introduced in Divine Rivals. It is not Book 3 of Letters of Enchantment and is not required to finish Iris and Roman’s duology.
These Divine Rivals notes focus on first-read decisions: why the first book matters, why some readers mistake it for a standalone, and what kind of romantasy it is.
Read Divine Rivals first because it establishes Iris and Roman, the magical correspondence, and the wartime stakes. Ruthless Vows continues those same threads and provides the resolution.
No. Ruthless Vows is the direct sequel and should be read after Divine Rivals if you want the story to make sense and the emotional payoff to land.
It means you can start the series knowing the ending already exists, but you still need both books for the full story arc. The first book is the setup; the second book is the resolution.
The first book has a strong emotional arc, a clean title, and a clear central couple, which is why some readers assume it stands alone. It does not. Ruthless Vows continues the same relationship, the same magical correspondence, and the same wartime conflict.
It means the series already has a finished ending, so you do not need to wait for another sequel. It also means book one is only the setup, while book two provides the actual resolution.
Iris and Roman are professional rivals, so the dynamic is driven by competition, distance, and emotional tension rather than deep hostility or villain-level hatred.
Yes. It is fantasy romance with magical letters, gods, war, and a central romantic relationship. The fantasy is lighter than in some adult romantasy series, but the romance is a core part of the story.
Divine Rivals is low spice. It leans on longing, emotional intimacy, and relationship development rather than explicit heat.
