Goodreads Synopsis: 

Deadly tarot, wicked schemes, dangerous alliances . . . can you survive the Forge?

Sexy, action-packed, and brimming with magic, A Vow in Vengeance is an unputdownable romantasy debut.

Rune Ryker has nothing left to lose. Everything’s been stolen by the Immortals—her family, her home, her freedom. But she’s done playing by their rules.

Each year, humans are forced to journey into the Immortal Realms, but twenty-year-old Rune orchestrates her own selection, determined to find her family and destroy anyone who stands in her way. Rune is used to doing whatever it takes to survive, and now she must endure the Forge, a cutthroat college for the Immortal druids’ elusive tarot magic. When Rune’s magic reveals itself to be the rarest and most powerful, she must live with its only other wielder—Prince Draven. As arrogant as he is ruthlessly ambitious, he’s the last person she can trust.

Rune’s abilities also draw the eyes of the most dangerous druids in the realms. Some want to use her. More want her dead. Draven offers to train her . . . for a price. As Rune becomes ensnared in Draven’s dangerous games, she learns there are secrets at the heart of the kingdom that some will kill to protect.

And Rune and Draven’s growing attraction may be the spark to ignite a brewing war.

Review: 

This book... was... so... good. I read most of this book in 2 sittings and it was only because I had to force myself to put it down to go to bed. I learned about this book during a virtual author panel and have been thinking about it non-stop since August. I received a review copy and had to force myself not to read it immediately... because I knew that it was going to give me a book hangover and it wasn't out until now (January 2026)

I am so happy that it lived up to my expectations and I am thrilled to have read it. 

The book follows Rune, a mortal who is part of the Selection, a ceremony by the magical realms to claim mortals for their use. She is taken by the Druids and now has been transformed into an immortal being. Part of this race is their magic, a tarot card based system where you are attuned to a power/ Arcane Major and not surprisingly, Rune gets a very good one. She comes with a lot of hatred and rage for the immortals and now especially for the Prince that is always around her. 

This book packs a punch, it is action and adventure, and romance and swooning and the magic system is my new favorite thing for a book. 

Characters - 

Rune is determined, super stubborn, and consistently aggressive. She has had to pave her own way making her independent and high-strung. As she progresses through this story, she learns that she is able to find joy and love in things that she was scared to before. She seems like a force and I can only imagine the rage that will progress through this series. I am so excited for it. 

Draven, the princeling, is a World magic user and he is both feared and revered, but he is lonely and withdrawn until meeting Rune. Their banter and flirting is delicious and the lead up to their feelings is intense and so swoon-worthy. 

The side characters Ember, Wynter, Morgan, Kesper, etc were also SO well formed. Each had a distinct personality and something to add to the story. While there were a lot of them, I never found it hard to tell them apart or understand their motives. So very impressive. 

The magic system - this was the first sell. Magic based on the Tarot. Each Druid is attuned to one and each has a very interesting power. Immortals use the power for a variety of things that the book does a really good job of teaching Rune about the system, so as the reader you get that education as well. Between her classes and the practical uses of the magic in the plot, the build up here was wonderfully done. The other races - Seraphs and Elves also have magic but they operate differently. 

The world - this was such an interesting world-build. We start in the mortal realms and then head into the Druid lands of the immortal realms. I really appreciated having a map, but the author also did a fantastic job piecing it all together throughout the story. 

Overall, if you are looking to dive into a new romantasy series... this IS IT.
