There is something wildly satisfying about a romantasy that entertains you and quietly challenges you at the same time. A Vow in Vengeance by Jaclyn Rodriguez does exactly that.

At its core, this debut in the Immortal Desires series follows Rune Ryker, a young woman on a revenge mission. She infiltrates the Immortal Realms, specifically the Druid Kingdom, determined to tear it down from the inside after her family is taken. What she finds instead is far more complicated: a dangerous magical academy, a reluctant alliance with the powerful Prince Draven, political secrets, shifting loyalties, and a war simmering just beneath the surface.

And yes, there is enemies-to-lovers tension. Deliciously so.

But what stayed with me was not just the romance or the revenge. It was the theme of assimilation.

Compulsory Immigration and the Weight of Being Chosen

In this world, there is a kind of forced migration built into the system. People must present themselves to be chosen by other kingdoms. Imagine that. Your future tied to whether someone else selects you.

Rune makes a calculated choice to show herself, to be picked by the Druid Kingdom, not because she longs for it but because she needs access. She needs answers. She needs proximity to power. She needs to find her family.

That hit me.

As an immigrant, I did not choose to come to the United States. My parents did. And from that single decision unfolds an entire life shaped by assimilation, both unconscious and conscious. The subtle bending. The code-switching. The internal negotiations about who you are allowed to be.

Watching Rune step into a kingdom she plans to destroy, only to slowly recognize its complexity, felt honest. She begins to see the pros and cons. The humanity and the corruption. The benefits and the cost. It mirrors what so many of us experience when navigating systems we did not design but must survive within.

That layered tension elevated this book for me beyond entertainment.

A Tarot-Based Magic System? Yes, Please.

Let’s talk magic.

The tarot-based magic system is one of the most creative fantasy mechanics I have read in a while. As someone who owns multiple tarot decks and uses them for clarity and reflection, I appreciated the way Rodriguez wove arcana into power, hierarchy, and identity.

It did not feel gimmicky. It felt researched. Intentional. Symbolic.

There is something deeply satisfying about watching archetypes from tarot take shape within a magical academy setting. It adds educational depth without slowing the pacing. If you are a tarot reader, you will smile at the nuance. If you are new to tarot, you will probably end the book Googling Major and Minor Arcana.

That is good fantasy. It expands your curiosity.

Enemies to Lovers That Actually Makes Sense

Rune and Prince Draven are not just thrown together for drama. Their alliance is born out of necessity. Suspicion. Strategy.

And that is what makes the romantic tension work.

Draven is powerful, controlled, politically aware. Rune is strategic, guarded, fueled by vengeance. Their dynamic is not insta-love. It is layered. It is charged. It is built on survival first.

When enemies-to-lovers is done well, it forces both characters to confront their own biases. Their own assumptions. Their own inherited narratives.

This one delivers.

Complex Family Dynamics and Buried Secrets

You already know I am a sucker for complicated families. Give me generational secrets. Give me unspoken truths. Give me siblings and parents and fractured loyalties.

This book does not shy away from that.

The family dynamics feel real. Messy. Incomplete. Not everyone has the full picture. Not everyone is innocent. Not everyone is villainous either.

That gray space is where this story thrives.

The secrets ripple outward into the broader political conflict, making the brewing war feel personal rather than abstract. When war threatens, it is not just kingdoms at stake. It is people. It is history. It is bloodlines.

Entertainment With Substance

Is this book entertaining? Absolutely.

Magical academy setting. Revenge plot. Political intrigue. Slow-burn enemies-to-lovers romance. Tarot magic. Brewing war.

But what I loved most is that it made me think.

It made me reflect on assimilation. On belonging. On what it means to enter a foreign system with no clue what one is getting themselves into.

Rune begins with a single objective: bring it all down. What unfolds instead is growth. Complication. Moral recalibration.

And that is the kind of character arc I respect.
