BOOK SUMMARY:
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.

SO THIS WAS GOOD?
Not gonna lie, this wasn’t really on my radar until my aunt messaged me and said I would like this one and she was right!! I just sat here glued to my headphones devouring the duet narration and all of the things this book held.
I reallllly liked the main characters. Flawed and grumbly with a good sense of self. The chemistry between Rune and Draven was fantastic. There was a solid level of slow burn where I actually go to enjoy them banter and get to know each other. And Draven is such a big softie?! I’m kind of obsessed with him honestly.
The plot wasn’t anything new but the writing worked so well that it wasn’t a deterrent. I liked the tarot card magic system and the general ideas behind the plot and themes. It felt like an easy read with well balanced world and character building.
I am a little worried with how book two will go because having an end game couple so solidified in book one doesn’t often work well for me in book two but I am crossing my fingers it doesn’t go that way and I can’t wait to pick it up!!
