Letters of Enchantment Reading Order
Read Divine Rivals, then Ruthless Vows. These two books complete Iris Winnow and Roman Kitt's story.
This guide avoids plot spoilers. The linked recaps contain full spoilers for their respective books.
Main duology
| Order | Book | Recap |
|---|---|---|
| 1 | Divine Rivals | Full spoiler recap |
| 2 | Ruthless Vows | Full spoiler recap |
Ruthless Vows follows the first book directly. Start with Divine Rivals so the characters, letters, and war develop in the intended order.
Where Wild Reverence fits
Wild Reverence is a separate adult novel set earlier in the same world, focused on Matilda and Vincent. It is not a third installment of Iris and Roman's story.
For this reading path, finish the duology first and then add Wild Reverence if you want another story about this world's gods. The publisher describes it as a standalone, so it can also be read independently.
