Arthurian Fae Quest…say less.
Format: Kindle
A fae centered Arthurian tale unlike any I’ve read so far. The author did a great job at descriptive world building, with scenes easily playing out in my minds eye. There was plenty of action, suspense, and even a touch of horror. An enemies to lovers, slow burn romance, a quest, with plot twist and turns aplenty. There was a love triangle, which I’m not usually a fan of but, it played out well in this story line. The FMC, Morgan Pendragon, was so blatantly naïve, yet I typically expect as much in a ‘book one’ of a series, especially one that features a fairly sheltered princess. I was happy to read that in spite of this, she still showed a strong sense of morals, fire, and spine. Now our MMC? Kairos Draven, aka Void’s Edge. Oh, how I’m a sucker for a smoking’ hot grumpy warrior alpha with a witty mouth, and a strong sense of “touch her and die” attitude, so you know who held all my cards. That ending? Just made me swoon all the harder. Now add a battlecat that rivals the size of a horse…and well Ms. Briar Boleyn you have well and truly stolen my heart. I’m excited to see where the story goes from here, and follow along to see more of the characters growth. I went into this story fairly blind, and I think I enjoyed it all the more because of it.
Once the story got going, it had me in an absolute chokehold and it was difficult to put down.

Not a bad start

Thank you Netgalley and Briar Boleyn for the ARC!
A camelot/king Arthur retelling with fae. I was hooked by the idea of this book immediately and was eager to jump into this world.
• slow burn
• enemies to lovers
• who did this to you
Morgan Pendragon watched her mother die by her father's hand when she was just eight years old, hiding under the bed. Morgan is believed to have the tainted blood of the fae in her veins and is cast aside so that her fathers illegitimate son, Arthur, can become the king. She's seen his cruel treatment of the fae firsthand, so when he sends her on a journey to find a fae weapon she seizes the opportunity to do more with her life. Along the way, she finds more than she could have imagined.
I don't know a whole lot about King Arthur and Camelot but I had a lot of fun with this story! The plot has some similar tropes to popular romantasy books (From blood and ash) but there's enough originality here that it doesn't feel like I'm reading a copy. I liked how the fae were different in appearance than what is typical in most fantasy books I've read. In this book they have blue hair, violet skin and a wide range of other characteristics. I thought that the world building was easy to follow and I could easily immerse myself into this world. After reading the blurb I kept wondering when she was going to go on the journey to find Excalibur and it doesn't happen until around the 45% mark.
The story is a bit slow at times but starts to pick up once they begin their journey to find Excalibur. The John Wick style Inn was a fun concept that I enjoyed reading about.
There are a lot of similarities to this and FBAA and I would have liked to have it be a little more different, but I'm hoping book two will have the story turn into something of its own. Overall I enjoyed reading this story and I'm looking forward to reading book two especially after that ending.

Right from the start, I was drawn in by the prologue!!!
Format: Paperback, Format: Paperback
Queen of Roses (Blood of a Fae #1) by Briar Boleyn
Genre General Fiction ( Adult), Romance, Sci-Fi & Fantasy, Dark Romance
“More primordial than the stars. My name was on his lips as he promised unspeakable darkness to any who came between us.”
Right from the start, I was drawn in by the prologue!!!
I’m a big fan of “touch her, and you die” vibes, but I mean, what’s also not to love about a unique Arthurian retelling with gender twists, a treacherous royal court, a dangerous quest, magical Fae & mystical monsters, entwined with a bit of spice!
Morgan, Princess of Pendrath and true heir to the throne has spent most of her life dimming her light to feel safe and to make others comfortable. She is treated as an outcast in the court and repressed by her family due to the blood of the Fae within her and forced to join the Temple of the Three as a priestess in training to one day replace Merlin.
Her brother, King Arthur, who reminds me of Joffrey from Game of Thrones, later tells her that he has other plans and offers her a choice of the Temple or to marry her off for political gain, unless… that is, she can journey through the great unknown and return with a long-lost fae weapon with enchanted powers known as Excalibur.
Her quest begins with a roguish crew that includes the mysterious, arrogant, and heart-tuggingly handsome Captain of the Royal Guard, Kairos Draven, whom she can’t decide if she wants to stab or indulge in pleasure with.
Along the way are plenty of surprises, mystical creatures, and betrayal, all while Morgan uncovers more of the truth about herself and who she can trust.
This book had intriguing storylines and lovable characters that kept me turning pages and wanting more. I can’t wait to see how it all unfolds and comes together in book 2, Court of Claws, which I just started reading!!
Read if you’re into-
Dark Fantasy/Romance
Slow–Burn

3.5 stars, A little boring to say the least.
Format: Kindle
Wow so I'm not sure where to begin on this one. This was a very different take on the legend of Arthur and Excalibur. This is told from the point of view of Morgan the sister of Arthur. Honestly the first 50% of this book is world building and character building which unfortunately was super boring for me. Morgan to me was a female MC that had a hard time in believing in herself. Sometimes taking too long to understand exactly what was going on around her. Draven was also a different male MC, like I couldn't put my finger on him and what he was all about. It was not until the last 10% of the book did we get some answers on the mystery that is Draven. The other 50% of the book centered around this big journey with everyone having a different motive. We see a spark of magic around this time that had me excited but then we never expanded upon that and what it could mean for the female MC. I feel like I want to read the second book just to see where this goes, but the spice was probably a 2 out of 5. Side characters are ok, Lancelet was fun but I almost felt like I wanted more.
