Thank you so much Second Sky for sending me this ARC!
The Serpent’s Throne is the last book in a Dark Fantasy Romance series and I absolutely loved Nadi and Raziel’s story, this series is phenomenal!
This is such a perfect conclusion to Nadi and Raziel’s story that I’ve come to love so much. I had really high expectations and it was even better than I expected with, as always, many secrets, scheming, plot twists, and amazing scenes with our main characters along the way. This book starts right where the previous one left off on that cliffhanger and I was immediately sucked back into this wonderful story, the author created a truly fascinating world and we got to see even more of it here which I loved. Nadi and Raziel were as incredible as ever, they have grown and changed so much in the course of these books, but I loved how they are still morally grey, kind of selfish, make questionable choices and are unapologetic about it, they might both be monsters, but I loved how they accepted those parts of themselves and each other. They are finally embracing their feelings for one another and it was amazing to see, Nadi and Raziel have come such a long way from the beginning of their story and I loved seeing them together here. They were more open and vulnerable with each other and their chemistry and spicy scenes were scorching hot, I loved these two so much and already miss them, I hope we will get to see them again in the future.
The Serpent’s Throne is a perfect conclusion to an incredible dark romantasy series, I loved these books so much and recommend them to everyone. This series is seriously underrated and, trust me, you don’t want to miss it. I’m already excited for what the author writes next.

I jumped into this immediately after being invited to read it. Thank you so much for the e-arc second sky pub!
Utterly obsessed.
She did it again. The pages are sprinkled with MAGIC dust, probably dark and unhinged magic, but magic in every word that pulled me in and it did not let go. I was eating it up. I loved how much time we got to spend with Raziel and Nadi working together. Revenge plot was WORKING for this sequel in a big way to drive the story. Raziel is still unhinged, maybe even more so, while Nadi balances on morally grey. They're both broken characters that have dealt with a lot of trauma so I really loved touching on more vulnerable moments. The spice spiced. The banter was perfect, as always, between Nadi and Raz. And some banter I really loved... Which led to ultimate heartbreak. This was such a rollercoaster of emotions. It tore me apart. Even with a little heartbreak it had a lot more heart. I loved loved loved it. This whole series is one of my all time favorites.
Assassin FMC is always a win for me. And I loved Nadi the entire way through. Morally grey to black MMC. Banter. Revenge plot. Twists. Trauma. Heartbreak. Love and spice. Seriously just all of it worked to make one phenomenal story.
I also loved the worldbuilding and seeing the wilds. It is a well paced story that's written beautifully to go along with the clever plot. I am all the way obsessed with Nadi and Raziel.

I was so excited for this book, the last two have been a rollercoaster so I knew this final book would be the same and it really was!
This story starts where book two ended with Nadi and Raziel entering the Wild. With both of them being outcasts from their kind they have no-one but each other but they'll need allies to try and take down Raziel's family.
This story was jam packed full of action, betrayals, murder attempts and of course war!

Amongst it all is Nadi and Raziel's relationship, I love how he's a monster but he's her monster 😍
This was a great ending to the series and keeps you on the edge of your seat pretty much all the way to the end!

Such a perfect ending to a perfect series.
What. A. Wild (see what I did there?). Ride!
This series has had me in a chokehold ever since The Serpent's Bride.
Nadi and Raziel are a pair that never should have been...two monsters who kept choosing each other...but wow you're rooting for those two!
This final installment of the Bloodlines series is jam packed full of heart-stopping moments, betrayal after betrayal, and breath-stealing revelations.
There is no down time in this book, we go from one crisis to another and everything is important!
I love when a book can keep me on my toes, and even keep me guessing about what our characters are going to do.
Nadi and Raziel are going to stay with me for quite some time, I loved this series so much!
Overall: highly recommend
Spice: open door

May 21, 2026The Serpent's Throne by Kathryn Ann Kingsley is book three in the Bloodlines Series. For best reading experience I recommend to read the books in order. The previous books are The Serpent's Bride and The Serpent's Sin.
The books are published by Bookouture.
Nadia and Raziel's story continues. On the run from their enemies, hunted and in permanent danger they still manage to have their lets call it private moments without losing focus on their endgoal. Fast paced, complex, unable to put down, this spicy dark romantasy is a wild ride that gives all the feels.

The Serpent's Throne is the final book in Kathryn Ann Kingsley's Bloodline trilogy, a dark vampire romance series.
It's a great finale, with some very satisfying romantic declarations between enemies-to-lovers Nadi and Raziel and some dramatic confrontations with their enemies. I raced through this final book and had a great time! The whole series commits to its dark themes, and it truly is enemies-to-lovers within a brutal world.
