The Realm of Endless Night
“Love is a luxury, my lord, one I simply cannot afford. When survival is of the utmost priority, one cannot simply go haring off after dreams.”
The Isle of Eidolon, 1812
Much like a page from a novel, the rich foreign lord is smitten at first sight with the beautiful housemaid. Theodora Maccowen simply never thought it would happen to her. Yet, Lord Rhidian Ríoga wants her as a wife, and what a lord wants?
He gets.
Whisked away to her new husband's home in the frigid far north, Theodora discovers Síochara House is more palace than manor and far grander than her wildest imagination could have conjured. Yet a darkness lingers within its magnificent halls that the dwindling winter sunlight cannot seem to dispel. Secrets lurk in every corner, the truth twisting and changing as much as the rooms and corridors do.
Plagued by dreams of monsters and occurrences which defy all rationality, with each passing day, the reality of Theodora’s situation grows ever more dire. Even her husband, whom she thought to be her ally, conceals as much as his house and people do. With nowhere to turn, she is caught between the struggle to be the perfect lady wife and her growing terror of what ought to be home... and the beasts she is certain dwell within.
For fans of The Invitation, Crimson Peak, and Raise the Blood, The Realm of Endless The Secrets of Eidolon is a standalone dark and spicy gothic historical fantasy romance set in the Regency era and is part of the Otherkind Universe. This book is intended for mature audiences only. For more information regarding tropes and content, please visit the author's website.

I received a copy of this book from the author and am voluntarily leaving this review. All opinions are my own.
I LOVE being just as confused as the MC when reading a book, and oh boy did this book deliver. For nearly the whole book i was sitting there with Theodora like “yeah you are 100% correct girl, there is SOMETHING wrong here but i have no idea what.” This book had me on the edge of my seat and has the same vibes as every horror movie where they go “what are you talking about, ghosts aren't real” while the ghost is actively murdering everyone in the film. All this to say i loved this book so much. There is so much more i wish i could say but it all feels like spoiler. This book was amazing, and I loved it all, especially towards the end. I was not sure if Rhidian would win me over, but oh my god, he did. I would love to see more of these characters just out and about living their lives. I also loved so many of the side characters and would love to see them have their own stories because I need more from this world.

What happens when you mix "The Hacienda", "Raise the Blood", "The Invitation", and "Crimson Peak" in a blender and add in delicious gothic spooks and spice? You get "The Realm of Endless Night"! I feel like I have outdone myself with this one!

This book! I'm not even sure how to review it. Compare it to other books? Can't. It's unlike anything I've ever read. Talk about how it made me feel? Ummm rollercoaster! You love the MMC. You hate the MMC. You love the MMC even more! And the FMC... Her journey and character arc is incredible. How do you go from meek and submissive 'my body belongs to my husband' to powerful goddess 'bow before me?' If you're Gisele Briseia, you give us 700 pages of gorgeous gothic writing while you put the FMC through h*ll to get there!
Honestly, this is one of those epic incredible books that you just have to read for yourself. Check the trigger warnings for sure, prepare yourself for some dark and heartbreaking moments, and buckle up because it's an amazing ride! Seriously, just go read it!

December 9, 2025The Regency (if Jane Austen era, as I believe was suggested in the forward?) writing style ("said I" "replied I") of writing was not for me, but the vibes are definitely on point in terms of Gothic tone. I just don't think reversing word order is necessary nor effective here and was rather distracting. Austen didn't write in first person and it sounds weird to have that style+first person narration. It feels like a darker Rebecca, so the premise is very intriguing. I just can't read further with the weird (historic) syntax.

I don't know if I can ethically review this since I edited it, but Gisele wants a review quote for Insta, so... "Fun, sexy, spooky. Pretty much everything I want out of a Gothic."
