Vow of the Undead: Bloodrune Saga, Book 1

by Elsa Frey

About this book

Exposed as a witch and bound for execution, Silver refuses to show fear.

Her defiance captures the attention of King Drakkar, a ruler feared for his ruthlessness and secrets. He spares her life on one condition: that she becomes his wife.

But belonging to the king is just as deadly, because the royal court of this vast and brutal Viking world is teeming with vampires.

To survive the court's blood-soaked games, she flees, only to fall into the hands of the Gods, who mark her for a far darker fate: become their chosen huntress and kill the undead. And then there's the king, who will do anything to retrieve his runaway witch… even wage war against gods.

Caught between divine manipulation and the king's consuming devotion, Silver must decide: Will she become the gods' weapon—or return to the man who claimed her freedom, her powers… and something far more dangerous: her heart?

Book one of The Bloodrune Saga: an epic and dark romantasy steeped in Norse myth, brutal court politics, and forbidden love.

This book has a toxic love triangle that ends on a steep cliffhanger, and there is no happily ever after until the trilogy concludes with book three!

Perfect for those who love morally gray rulers, power-laced tension, forced marriage, brutal court politics, and forbidden devotion. Fans of Carissa Broadbent, Scarlett St. Clair, and Danielle L. Jensen will feel at home with The Bloodrune Saga. Dark themes, slow-burn intensity—listen responsibly.

Reader Reviews

A really great read, a vague review, and a long wait walk into a bar…

May 15, 2026

This series has joined my list of favorite fantasy reads. Vampires, witches, Norse mythology, three of my favorite things. It’s really a fun (and heart wrenching) read. I saw the book mentioned on social media and I figured I’d give it a shot, especially since it’s on Kindle Unlimited. I’m really glad I did. The story was a fun, heartwarming, heart breaking, and crazy ride (in no particular order) and I’m glad I gave it a shot. I think I read the first two books within a week. The fact that the...

The book is great but some of my pages are coming out. I do not bend the spine of my books or anything like that so I’m no sure why )

Vow of the Undead

September 3, 2025

This book started off super strong but the by the halfway mark it started becoming very confusing. The beginning introduces us to the FMC Silver, who is a witch and hides her magic because it’s illegal. Norse mythology (or at least the Norse gods) is used heavily in the first half of the story which is super interesting but it mostly disappears from the second half. Silver gets selected for execution and ends up being saved by Drak, who is the King, and eventually is taken to his castle....

Not worth the read.

It gets two stars because it kept me reading, which was only because of the \"cheap thrills\" of heated interactions with the \"love\" interests. Without those moments, it would have been an easy one star. The premise doesn't make sense. They are in a fantasy realm, not Midgard, but yet the whole plot is founded on the existence of Norse gods and Norse mythology. She could have just created her own pantheon and mythology. The FMC first saw the king at a track race. I cannot make this up. Then...

Vampires, witches, and Vikings what more do you need

November 24, 2025

Vampires, Witches and Vikings need I say more. This book pulled on my heart strings and cliffhanger at the end left me needing book 2 asap. The plot and mythology was good. The character were fun and I adored the banter. I can't wait for book 2. )
