“There are darknesses in life and there are lights. You are one of the lights...The light of all lights.” - Master of Salt & Bones.
REVIEW: This book follows Isa who lives with her aunt on an island. Isa begins a new job as a caretaker for the dark, and mysterious Blackthorne family. A family who is disliked and even feared by the rest of the inhabitants of the island. However, as she grows closer to the man who they call the devil, Lucian Blackthorne, Isa sees for herself what the truth of Blackthorne manor really is.
This book is a dark romance! Originally I was told it was fantasy, which I don’t agree with at all. It is more of an erotic, gothic feel with some mystery sprinkled in. The plot was very interesting and kept me intrigued. This book was also quite steamy, however, I felt those scenes were well done and didn’t take away from the rest of the book.
Overall, the content in this book is quite dark and the backstories of the characters involve potentially triggering matters. Be aware to look these up if you feel like you need to. Overall, this is the first book I have read by Keri Lake, and I am excited to read more.
SYNOPSIS: When I was a little girl, I dreamed a handsome knight would come and rescue me from my wretched mother. He'd ride up on his white steed and break the curse I've been fated to carry since the day I was born.
Funny how things changed over time. How the fairy tale twisted into something far more crooked, darker than I ever imagined.
In reality, my knight is scarred and broken, living alone in a castle of bones that overlooks the sea. He isn’t searching for me. He never was.
Lucian Blackthorne is as cursed as I am, and equally shunned by the locals, the fishers of men, who believe him to be the devil in the flesh. Perhaps he is, with the way his amber eyes draw me in, ignite me like an infernal blaze. And the sins he whispers in my ear are as wickedly intoxicating as the man himself.
Yet, his touch is heaven and his will is my weakness. He calls us forbidden, an unsalvageable tragedy, with no happy end. Maybe we are. But in this story, he’s the one who needs saving.

“we’re the composers, the conductor’s of our own fate, and we write the notes to a beautiful, dark melody that no one else can hear.”
this book was AMAZING ❤️🔥
i couldn’t put this book down for anything .
this book gives beauty & the beast / phantom of the opera vibes with a lot more going on . Lucian hires Isadora to help take care of his mom, not his nurse but a companion for her . Isadora has a painful past & she’s willing to do anything to get out of town to make some money , even if that means working for a guy with a thousand bad rumors about him . the way Lucian talks to Isadora is like he’s speaking poetry without even trying . the wording & quotes in this book were chiefs kiss . the spice in this book was gold 🔥 the plot of this book is super original & sooooo twisty . i think there were 5 different twists at the end & i had my jaw on the floor at all of them .
literally obsessed with this book . the writing was beautifully done 🫶🏼
this is my first book by Keri & i will now be ordering more from her immediately🖤
this book is definitely in my top reads of the year!
as always check your TW 🤍

4 star read - dark gothic romance
Format: Kindle
Master of Salt and Bones by Keri Lake
4 STAR READ
“You’re my curse. Staying away from you, is like trying to hold my breath when the tide is rising.”
This book reminds me a lot of Nightshade, also by Keri Lake, but without the fantasy element. It gives off the same gothic vibes, including flash backs, history of abuse, and sexual deviances. It also has some overlap with the older male character obsession that is seen in Nocticadia - though Lucien doesn’t hold a candle to Professor Bramwell.
SUMMARY
Lucien was abused, lied to, and manipulated his whole life, by everyone who should have protected and cared for him. A wealthy heir to a massive fortune, he is hard, dark, and delicious. The story unfolds across two timelines, jumping between Lucien’s past and present, and Isa’s POV. Lucien is viewed as the devil of Tempest Cove, covered in scars and rumors abound involving the death of his wife and son. Isa is the daughter of the town whore, who has struggle to fit in and cope with the tribulations of her life. Lucien hires Isa to be his mother’s companion, to keep her company and encourage her to get out of bed each day. As they continue to bump into each other and interact, their relationship develops beyond his dark obsession. Lucien is wary to get attached as his connection to a dangerous secret society puts everyone he cares about at risk, however there may be no way around Isa’s involvement.
WHAT I LIKED and DISLIKED
It was a great story full of tragedy and resilience. Both characters have deep back stories that unfold throughout the book, we get information at just the right time to make things make sense. It is really well told. It does feel a bit slow in the middle, I took a mid book break to read something else but came back to it and wondered why I stopped - the reason I gave 4 stars was because I had the need to take the break. Which tells me I lost interest during part of it.
Lucien has so many layers and each one is full of sadness and devastation. Isa’s story is tragic in its own way, however her youth has her dealing with them in a difference way - she is definitely more detached in her own way.
There is an age gap - Lucien is 33, Isa is 19 — I’m not usually a fan of this kind of age gap, but Isa isn’t childish or immature so it works. The book definitely gives Grumpy x sunshine vibes. The spice is well done and paced well throughout the book.
If you like spicy, gothic, dark romance and have enjoyed other books by Keri Lake this book will not disappoint.
There are references to rape, sexual abuse, physical abuse, and mental illness — I would check any triggers before reading

It’s been a few years since I last read a story by Lisette Marshall, and I was instantly reminded why I love her work. Lisette is a master of weaving together rich fantasy worlds, complex characters, and heart-stopping romance.
Lisette builds amazing worlds, develops intriguing characters, and crafts plots full of twists and turns. The final 30% had me wide awake in the middle of the night, anxious, thrilled, but also kicking my feet and grinning like a fool. Lisette truly knows how to build tension and then deliver an ending that causes a complete and utter crash out.
The dynamic between Thraga, a rune witch on the run, and Duralin, a necromancing fire mage with secrets of his own, was absolutely electric. Their banter? Unforgettable. The dialogue was brimming with wit, tension, and just the right amount of venom. Underneath all that verbal sparring, though, was a surprising tenderness. A quiet, aching vulnerability that made their connection feel raw and real, while being layered underneath a resistance full of tension and hidden yearning.
I especially admired the OCD and anxiety representation woven naturally into the story; it added authenticity and depth without ever feeling forced. The nature of OCD is repetitive, and the reality of anxiety is that it is always lurking beneath the surface. I found the representation to be so realistic and relatable.
The world-building was lush, the mystery was gripping, and the slow burn? One of the slowest and most satisfying I’ve ever had the pleasure of reading and experiencing. The story unfolds entirely through Thraga’s POV, but Lisette gifts us a glimpse into Duralin’s mind at the end, truly, a perfectly placed moment that leaves you thirsting for the next book.
The Death-Made Prince is everything I want in a fantasy romance: morally grey characters, delicious tension, sharp and cutting banter, and a world that feels alive with magic, secrets, and mystery. It’s easily one of my favorite reads of 2025, and I cannot wait to see what comes next.
This is absolutely one of my favorite reads of 2025. I highly recommend The Death-Made Prince by Lisette Marshall.
Happy Reading, Friends xx
