A Union in Thunder

Rate this book
In war-torn Proventium, noble daughters earn suitors with a dowry far greater than magic. Lacking offensive powers, Lavinia Bruis is determined to prove her healing magic is not a liability through an auspicious match. Though the match she longs for, her childhood love, Oran, is out of reach, she always expected to survive in a loveless marriage. What she never expected was to catch the interest of the king—a husband three wives have not survived.

Plagued by rebellion and the Wasting, a rot draining the land, King Alaric is desperate to find the kingdom's salvation. When he deems Lavinia the bride prophesied to end the turmoil, she is fated with an impossible task, one that, should she fail, will earn her a place on the executioner's block. Faced with the brutality of King Alaric's rule, Lavinia must confront her true her kingdom, her family, or her heart.

Fire wielder Oran Lennox's loyalty and heart had long been torn between his homeland, subjugated Tythmore, and his love, Lavinia. Refusing to endanger Lavinia with the rebel cause his father died for, Oran felt doomed to love her from afar until the fates of Lavinia and Tythmore become intertwined. Committing to the rebellion may be the only way to save both Lavinia and Tythmore from King Alaric's cruelty.

As the binds of the prophecy demand they decide between using their magic to fight for their warring homelands or the home they've found in each other, Oran and Lavinia must discover if their love is strong enough to fight fate.

OH MY GODDDD

finished this approx 20 seconds ago & trying to form a single complete thought is proving difficult

To know:
- Fantasy kingdom where power grants you influence at court
- She’s the daughter of a royal house. Has healing abilities
- Her father insists she’s married off this season
- The one man she wants, she can’t have (her brother’s best friend!!! TEAAAA!!!!!)
- Brother’s BFF: Tall. Hot. Fire magic. Down - all caps - BAD for her


rapid fire reactions:
- Oran. Hot. Literally.
- Him casually turning a guy to ash with little to no effort!!!!!
- when I see her brother it’s ON SIGHT
- no like can someone kill [redacted] immediately????
- I love her aunt & Ruby <3
- I was so stressed out during that scene at the end I was holding my breath thinking someone was gonna interrupt
- desperate for Oran to just straight murder everyone if I’m honest - SORRY IT’S TRUE
- I don’t hate Rhodes & I won’t apologize for that opinion!!!!

Had an absolute BLAST reading this & am left with my jaw hanging open and the need for book two in my hands immediately

Five stars. Fantasy romance readers will love this. Historical romance readers will love this. I LOVED THIS.

update: I will kill [redacted] with my bare hands - THAT WEASEL

Someone get me a beta blocker because my adrenaline is through the roof after the last 75 pages of this book. Romantasy meets regency and I’m hooked.

Review of advance copy received from Author

I do not usually read this genre; I usually reserve a 5 star for the greats like Morrison and Fitzgerald and Boyle. Here is the epiphany: I realize that a really great book doesn't need to be awarded and lauded by the throngs. It needs to grip you with the story and the characters as well as speak about a powerful truth. This novel does both.

Beyond the compelling story of Lavinia and Oran, the tale speaks of the truth of women through centuries- that they had to and have to reconcile the conflict of being simultaneously told we are irrelevant and essential at the same time, dismissed, yet controlled because of our importance. Lavina's love story is compelling, but her realization of the stress all women in her world suffer because of their lack of autonomy truly elevates this novel. Don't let the romance and heat of this story beguile you into dismissing the power of the underlying themes.

I love the complexity of the tale and the stark truth of its message. I cannot wait to see how this resolves itself in the sequel. The author better hurry up!

It's difficult to believe that this is the first novel from the creative mind of this talented young author. It's a clever new twist on medieval magic. Great story, great characters. Can't wait to read the sequel!
