I swore I’d kill Raziel Nostrom. Now he owns my heart…

After a shattering betrayal, Nadi and Raziel flee into the Wild—the endless labyrinth of caves that is home to the fae.

Nadi trained for years to infiltrate and kill a ruthless family of vampires. Now she faces an even deadlier challenge—returning to her own family with their most hated enemy by her side.

In a realm of flickering lights and terrifying monsters, the desire that binds her to Raziel only grows stronger. Enemies and allies wish to tear them apart, but she still craves his razor-sharp smile, his touch, his bite…

In the city above, Raziel’s siblings are building a new world, where vampires rule with no restraint and no mercy. Soon their power will be untouchable.

Nadi and Raziel only have each other. Two shattered and broken things, in a world that wants them dead. Two perfect assassins, sharpened to a killing edge and hungry for revenge.

Their love was forged in blood. And it will end in blood…

A thrilling and addictive dark vampire romance, the Bloodlines series is perfect for fans of Carissa Broadbent, Keri Lake, and Kaylie Smith.

“This was love, he realized. Not the pretty, sanitized version from songs and stories. This was love in its truest, most terrible form—the willingness to destroy yourself for someone else’s sake.”

The Serpent’s Throne not only kept up with the momentum of the previous books, but it somehow kicked everything into an even higher gear! The second I thought I knew how things were going to go, I was blindsided by more scheming! The betrayers were getting betrayed, and I swear every single person had at least two metaphorical (and sometimes literal) knives in their backs!

Nadi and Raziel have one of the most intense and complex love stories I’ve ever read, and I loved every second of it. Even after the enemies became lovers, they still had so much distrust and brutal history between them! They are both so morally grey (let’s be honest—almost black) that it makes for a delightfully dark dynamic. It’s angsty and delicious! The romance really keeps you on your toes in this series.

This was the perfect 5 star ending to a perfect 5 star series for me! I had the best time with all these books 🖤 If you’re into dark, urban fantasies with mafia vibes, I cannot recommend this series enough!

This was such an amazing ending to and an even more amazing dark romantasy trilogy. From the very first book I was absolutely hooked and honestly each book kept getting better that by the time I got to the end, I couldn’t believe it was over. This series is perfect for someone who needs a killer vampire romance that is full of twists and turns, cliffhangers, and romance that will have you begging for more.

Nadi and Raziel had one of the most intense, complicated and honestly, down right just fucked up at times, but I loved it so much. I think that’s why I loved their story so much. They both had been through so much and even though everything was falling apart around them, they always found their way back to one another. With so many lies, betrayal, and schemes, they were always in each other’s corner. I honestly love when both characters are morally gray, with to the point of being considered black. It makes their story so much more intense yet emotional, especially with that ending. Note to self if you read this series, you will experience heart palpitations so make sure you are near the closest hospital!

If you are into dark romances with a hot vampire villain, a fae assassin, revenge on everyone, twists and turns that will give you whiplash, and cliffhangers that will leave you on the edge of your seat, then look no further and add that a series to your TBR immediately.

*Thank you so much to Netgalley, Second Sky and Kathryn Ann Kingsley for the ARC!*

The Serpent's Throne was such a good ending to the Bloodlines series. I love how deliciously dark Nadi and Raziel are. I love how deranged they both are and that they match each other's freak. I loved seeing them in the Wilds with all the fae. Raziel had such a tough time, and it was so interesting to see. (I also cried during one scene.)

They are so in love with each other — at least I think so. Honestly, this entire series had me completely hooked. It's the perfect dark romantasy series; you seriously need to read it. And the third book didn't disappoint either.

If you are looking for a perfect dark romantasy with morally grey (or more like dark) character, read the The Serpent's Bride series.

The Serpent's Throne by Katherine Ann Kingsley

What. A. Finale.😱

I absolutely devoured The Serpent's Throne and couldn't put it down. Every chapter had me questioning whether Raziel was about to embrace complete chaos or show us the soft-for-her monster we've all fallen in love with.

I loved spending more time in the Wild and learning more about the fae politics. It expanded the world beautifully while constantly making me fear that Raziel might not survive what was coming.

The spice? As delicious as ever.

The final chapters were packed with twists I genuinely didn't see coming. Grandma really dropped some bombshells, and that's all I'm saying... but trust me, justice was served.

I'm so sad this series is over because I've loved every minute of this dark, addictive ride.

If you're looking for a dark romantasy with an obsessive morally grey MMC, fae, monsters, spice, dangerous romance, and a hero who absolutely should not be fixed, this series belongs on your TBR.

I can’t believe this trilogy is over, what a ride!

I loved Nadi and Raziel so much 🤭 They are both so ruthless and determined, they make the ultimate duo. I love how well they complement each other and the banter/tension was everything!

We once again continued straight from where the last book ended, so we got straight back into the action. I genuinely had so much stress reading this, it always seemed like it was just the two of them against the world and the odds were so against them, I couldn’t see how the two of them would win 😅 I am very satisfied with the ending though, some things I really didn’t see coming, but I think the plot really went in such a good direction, the ending was perfect.

If you love vampires and fae, and a bit of mafia vibes, then you need to read this trilogy!

Thank you to Second Sky and the author for providing me with an eArc in exchange for an honest review 😊

ARC Review!

What a conclusion!

Forget "I can fix him." Nadi is more of a "I'll make us both WORSE" type of girl, and I was HERE for it!

This was a fantastic conclusion to the trilogy--everything was appropriately wrapped up without feeling too perfect. We got the relationship development beyond the physical (who knew the Serpent could be VULNERABLE? GASP!), ...we got more of the physical relationship, a few near death experiences-- what more could you ask for?

This is DEFINITELY a bingable series--like, a "I read this in a weekend" type of read. It has everything that paranormal, dark romance, and mafia romance readers could possibly want. Except maybe another 2 books, because this was TOP TIER enemies to lovers. Because everyone knows the best enemies to lovers has them staying enemies LONG after the "lovers" part kicks in.

I had the BEST time reading this series and will definitely be reading more by Kingsley in the future!

Ooof, this trilogy truly exceeds my expectation. I didn't expect the highs to be really good and the lows to be really depressing. Gosh, and this ill-fated/star-crossed lovers trope? Buried me with it.

I don't know how else to praise this book other than it's a really damn good dark urban fantasy romance. It puts me in a very good mood. There was a little weakness with the conclusion act, but as a completed series, it's a BIG five stars read for me!

Highly recommended from yours truly.

This was a much needed ending to the trilogy, absolutely loved the aspect of discovering more of The Wild and the fae realm especially with Raziel. Unfortunately for me it lacked the depth and speed from the first two I was yearning for.

I was so shocked by a couple of the twists and had be quite literally sweating with fear and the development of the relationship had me swooning so much! I loved this softer side of Raziel away from his family.

Thank you so much Second Sky for the gifted copy, I truly loved this series so much!

After the cliffhanger in The Serpent’s Sin, I was genuinely excited to see how this trilogy would wrap up. Unfortunately, this finale didn’t quite land for me the way I hoped it would.

There were definitely parts I enjoyed. The time we spend in the Wild was a real highlight. It gave strong Avatar vibes with the glowing vines, the ceremonial tree, and this immersive, almost otherworldly atmosphere that was really well done. The secret deals, betrayals, and double-crossing kept me on my toes, even if at times it became a little tricky to keep track of everyone’s loyalties toward the end.

My biggest issue was the ending though. After so much build-up across the series, everything wrapped up so quickly that I barely had time to process what was happening before it was over. I kept waiting for more explanation, more detail, more something, but instead I was left with a lot of unanswered questions and a slightly confused stare at the final pages. It just didn’t fully make sense to me. See spoiler section for more details.

I also felt like the second half started to repeat itself quite a bit. The same thoughts and information kept coming back, and by the end I was really noticing it. That’s a personal pet peeve of mine and it definitely affected my reading experience.

The frustrating part is that I actually really liked the ideas at the core of this story. I just don’t think the execution of the finale worked for me the way it needed to.

If you’re here for vibes over logic, this might still really work for you. There’s plenty of action, strong atmosphere, and a relationship that pushes through everything.

Thank you to Second Sky for providing me with an eARC through Netgalley. All opinions are my own.




⚠️ SPOILERS BELOW ⚠️



I warned you.


My biggest sticking point: you’re telling me he drained her completely, there was basically no blood left, and then five seconds later she’s up decapitating the most powerful being in existence? I tried, I really did, but that just didn’t make sense to me. I kept thinking about it and wishing we got even a small explanation, because my logic brain fully refused to let that one go.

Very underwhelming. It was just like she wanted to wrap everything up quickly, and it had pacing issues for me.
Why did we spend so long in the Wild and then boom, 5 minutes and we are done with the story.

I can’t believe The Serpent’s Throne is the final book in the Bloodlines trilogy. What an incredible adventure this series has been! 🙌

Just like book two, this one picks up right where the previous one left off. Nadi, our favourite shapeshifting fae assassin, is back in the Wild with her own kind, and this time, she has the vampire serpent Raziel by her side. From the very beginning, you know you’re in for a wild ride. 👏

The fight for power and revenge continues, but this time there’s also something else possibly at stake… A future. Together?? 👀

These two are truly a match made in hell, and I mean that in the best possible way. 😜 They’re both unhinged, brutal, and ruthless, yet vulnerable in their own twisted ways. I absolutely adore these two characters.

Like the first two books, The Serpent’s Throne kept me on my toes and gave me plenty of “oooh” and “aaah” moments. The plot was definitely plotting you can say! There were a few moments where the pacing felt a bit slow for me, but overall I was so invested in the story and the characters that I happily kept turning the pages.

I was soooo desperate to find out how everything would end, and now that it’s over, I’m honestly a little sad for it to be over. 😢 But I do have to say, that I’m incredibly satisfied with the ending and so happy for my favourite murder-y couple. 🔥

Thank you so much to Second Sky and NetGalley for providing me with an eARC in exchange for an honest review.

If you’re looking for a dark fantasy series filled with vampires, fae, morally grey characters, enemies to lovers, mafia vibes, and an addictive revenge driven plot, then you need to pick up this series immediately! 🩸

“It’s impossible, it’s wrong, I’m a mad sadist and you’re a murderous fae, I killed your family … but I love you anyway. Completely. Desperately. However much I’m capable of, with this ruined soul of mine.” 🥹

An epic ending to a really great trilogy.

The Bloodlines trilogy has become a comfort series for me, and one I’m sure to re-read time & time again.

As with the previous two books, The Serpent’s Throne is fast-paced, morally black, and addictive, so naturally I ate it up. Each chapter brought so many twists I got whiplash, and the plot never failed to be exciting.

I didn’t think it was possible to love Raz more, yet here we are. Not really sure what that says about me, but let’s allow it 🤫. His love for Nadi in this final book brought out more character development for the pair, and added more depth than what we’ve previously seen. I’m not sure heartwarming love is the right word - perhaps depraved, and toxic to everyone around them? I was rooting for them so much; give me more of that!! I also really liked how there wasn’t a grand reveal that ‘secretly they are both soft and really lovely on the inside.’ It was refreshing to see they were both still bastards 🤣. Dark romance at its finest! 🖤

Aside from the romance, the big standout for me in this book was that we actually get to see more of the Wild and the fae. I found that super interesting, and it rounded the story perfectly.

If you want a dark romantasy trilogy that’s fast-paced, spicy, a good time read, and will keep you guessing what’s going to happen till the last page, get The Bloodlines on your TBR.

Thank you so much to Second Sky, Kathryn Ann Kingsley & NetGalley for the eARC 😘

Well, going in, we knew this was going to be the last book in the series, and obviously that is quite sad.

You get to know and love these characters. I mean, Nadi and Raziel have come so far since we met them in book one. It's been a while since I had read books one and two, and so when characters started popping up, I did kind of forget who some people were. Obviously, being the last book, you want to remember who everybody is. Everybody's got a part to play, and believe me, there were a lot of parts that needed playing; there was twist after twist after twist after twist. Just as one betrayal or one discovery had happened, and we were just getting through that, there was another one and another one, and Katherine Ann Kingsley definitely kept us on our toes.

Obviously, there's some scares along the way. Being the last book, you know, it won't be smooth running, and that was played upon. I quite liked the ending. It's wrapped. It's done, and it's sad that it's over.

You know, it's definitely a series I've really enjoyed. It's in a genre that I'm trying to read more about. So, if you're new to the fantasy, romantasy genre, then this is a good one to start with. You have Fae, you have vampires. I mean, I love everything with vampires in.

The story of a vampire and a fae at opposite ends, and how they fall in love. That's not a spoiler, by the way. Just gutted it's over, and I look forward to what Katherine Ann Kingsley gives us next.

A bittersweet end to an amazing trilogy. The Serpent's Throne's tone is very different than the first two as the series continues with Raz and Nadi trying to keep to their goals with how things ended in book 2. There's unseen alliances, plot twists, experiencing a love greater than a throne and revenge, and the power of a bond that breaks any prophecy.

A phenomenal ending to a great story. I am forever grateful and honored to have ARC read this entire series to leave these reviews in hopes many more will pick up Raz and Nadi's story that explores trauma, healing, inner conflicts, and how the reality of our lives tends to shift no matter how much we aim for one thing but need to adjust to our surroundings while including loved ones to grow, heal, and shape a life we're worthy of living.

Thank you to NetGalley for an ARC of this book!

I absolutely paced it through book 1 & 2 and was desperate to read the conclusion. While I really enjoyed this book, it did take me longer to get into than the previous two parts.

It was great to see the conclusion for Raziel & Nadi, and seeing them set out on their final mission to get revenge on his family was great.

This series was overall really enjoyable, and they’re great quick reads that get you really invested in Raz & Nadi’s stories.

This was a good ending to Nadi and Raziel’s story. I absolutely love Nadi and Raziel’s relationship even though it’s twisted and toxic to say the least. You can’t help but root for them and hope their murderous schemes work out. I truly enjoyed this series so much and though I’m sad it ended, I thought it ended well.

Thank you for letting me ARC this series! I can’t wait to read what you write next!

4.5 stars rounding up!

OMG I devoured this in one sitting immediately after finishing the second half of book 2 on my flight. I did not want to put this one down even for a second.

Although I still think book 2 was my favorite, book 3 was action packed, well paced, and had a fulfilling ending that I did not fully expect.

Be sure to check trigger warnings for this trilogy! The complete Bloodlines trilogy is available now!

2.5⭐

The Serpent's Throne es el libro final de la trilogía Bloodlines y yo lo he estado esperando muchísimo porque necesitaba que este libro cerrara con fuerza la serie. The Serpent's Bride (libro 1) fue everything I needed it to be, no fue perfecto but I ATE IT UP ¿Nadi y Raziel? TOP fucked up pair. The Serpent's Sin (libro 2) fue una situación… inicio bajísimo, con errores de edición y contradicciones que me fueron muy complicadas de pasar por alto, pero terminó tomando vuelo y el final me dejó DESEANDO MÁS. En mi mente, The Serpent's Throne era, en cierta medida, una suerte de redención para la trilogía y, aunque todo lo que quería que pasara pasó… No fue tan satisfactorio as I wanted it to be.

El pacing estuvo all over the place, las construcciones hacia los momentums de la historia iban lentos y pesados, mientras que la cúspide de tensión iba a la velocidad de la luz, al punto de que, como lectora, no encontraba momento para procesar mis emociones… no podía sentir tensión, intriga, miedo o alivio porque tan pronto como iniciaba a sentir algo pasábamos a la siguiente escena. Esto no se sentía action packed sino muy apresurado, especialmente al final. Son 298 páginas, no es un libro largo, por lo que considero que se pudo tomar más espacio para evitar este desfase.

En esta ocasión, ni Nadi ni Raziel, the master manipulators, controlaban la trama, lo cual, en cierta medida, era entendible teniendo en cuenta la situación en la que se encontraban. However, siento que esperaba ver más de sus mentes trabajando juntas para superar sus problemas… Cuando la realidad en el libro fue más un tema de suerte. Y puedo entender que Kingsley se encontraba en una posición muy complicada, sus personajes se habían metido deep in the hole… saber cómo sacarlos de ahí no se trataba de una tarea sencilla… pero creo que nadie se hubiera molestado si se tomaba un añito más para pensar en otra forma de encontrar resolución o en editar de forma más a conciencia lo que ya se tenía.

He leído varios comentarios sobre el cambio de actitud de nuestros personajes principales… que se han vuelto muy blandos, que actúan fuera de personaje, etc. Yo no siento eso en particular. Me parece que todo lo que están viviendo en definitiva ha influido en su personalidad, más no me parece que se trate de personajes irreconocibles a los del inicio. Aunque si leo un "I don't know" más de parte de Nadi creo que me voy a volver loca. En su defensa tho… yo tampoco sabría qué hacer en su lugar.

Puede que suene a que estoy siendo demasiado crítica, pero es que puedo ver una historia SO WORTH TELLING en estos libros. No tomen lo que digo como que esta trilogía no me ha gustado, no me arrepiento en lo más mínimo de haberla leído y dentro de todo disfruté mis momentos con estos personajes. Como dije, todo lo que quería que pasara pasó, no exactamente como lo hubiera previsto o me hubiera gustado, pero pasó, es más un tema de satisfacción final. Es triste que este libro no fuera el final que estaba esperando, creo que en esta historia en particular los stakes were really high, sin embargo, si lo veo todo como un conjunto de inicio a fin no puedo negar que la pasé bien.

Content Warning: violence, death

World Building: Nadi and Raziel are in the home of the fae, the Wild – which is an underground labyrinth. They make plans and need to escape, I like the symbolism of Raziel being deep underground in Fae territory and needing to climb all the way up to the surface to carry out his vengeance. In the Wild, we meet some of the Fae in power and learn about them and their motivations.

Characters: Nadi has chosen her side, and it’s Raziel so she does everything to take his family down. Raziel has gone beyond anger, he is the Serpent and will do anything to take down his family and rule. He has always been morally black, but I love how Nadi grounds him, just enough – I like how he knows what he is good at and had some sanity while he seemed like he was going insane. Kalo was interesting and we get to know more about him – at times I didn’t know what side he was really on but I did like his growth.

Romance: Nadi and Raziel are like Bonnie and Clyde and they will go down together with a world burning around them. I love how they were each other’s ride or die til the end! They have seen the best and worst of one another, and they are committed – I love that about them! Nadi sees all his red flags and things, I want that. 😅 Surprisingly this is the least spicy book among the three in the series, but I didn’t mind it because there was a lot of killing going on, no time for spice!

Story: This is a great ending to the trilogy! I like how Nadi and Raziel went about carrying out their plans and vengeance. They were in it 100% and I admired that about them even though Raziel is a little crazy. These two are made for each other, I love their crazy moments and heartfelt ones too. I enjoyed the journey Nadi and Raziel go through to finally achieve their goal. And the ending had a little twist I definitely wasn’t expecting.



Final Thoughts:

I was cheering Nadi and Raziel on because I wanted to see them get vengeance too. I liked learning about the Fae, the politics, the violence and the vengeance. I love the romance, I was all about them being crazy and crazy for each other. I really enjoyed this series and hope to read more from this author!

Tell me why these two are walking red flags... and yet I'd defend them with my whole chest.

This finale... pure CHAOS.

Every single time I thought I'd figured out the next move... someone got betrayed. Then the betrayer got betrayed. Then THAT person got stabbed in the back.

At one point I was convinced everyone needed name tags that just said: Potential Traitor.

And I loved every second of it.

Now let's talk about Raziel and Nadi.

These two are not your sweet little romantasy couple.

They are dangerous.

Messy.

Morally gray... honestly...morally black.

And that's exactly why they're so addictive.

Their love isn't soft.

It's earned.

It's painful.

It's full of history, distrust, impossible choices, and the kind of devotion that survives even when everything else falls apart.

Watching them choose each other over and over again (despite everything they'd done, everything they'd survived, and everything standing between them) completely wrecked me.

And somehow...I fell even harder for Raziel. (Which honestly shouldn't have been possible.)

The political scheming? Incredible.

The twists? wow.

The world somehow became even bigger in this final installment, and I loved getting to explore more of the Wilds and the fae.

But what stayed with me wasn't just the magic.

It was the people.

Their healing.

Their trauma.

Their impossible choices.

Their love.

Mood: Some series give you closure. This one stole my heart, shattered it into a thousand pieces... and somehow convinced me to thank it afterward.

If you've been sleeping on this series...Please wake up. Just make sure you don't have plans because once you start... You're not leaving this world until the very last page. And when you do? You'll miss them more than you expected.

Read this when you're craving morally gray lovers, political betrayal, enemies who never fully stop being enemies, devastating devotion, jaw-dropping twists, and the kind of finale that leaves you staring at the wall wondering how you're supposed to read another book.

Thank you to Second Sky for gifting me the eARC through Netgalley. All thoughts are my own.

Confession: I trusted absolutely no one... and somehow I was still betrayed.

Thank you from the bottom of my heart to the amazing author and the wonderful publisher, Second Sky, for allowing me this last time to read an ARC of this marvellous series on NetGalley!!

“We will kill each other or die at each other’s side”

“The fae assassin.
And the Serpent.
They would die.
Or they would rule the world.
Come what may”

“My bloody bride. My murderer. Whatever complicated, twisted, insane path having you in my life was going to lead down? I was going to follow it blindly … And I would do it without question”

Raziel and Nadi. Once again. For the last time. Together. Fighting for revenge. And for each other. Impossible. Forbidden. And yet, inevitable. I loved this last book in the bloodline series. I can’t believe it’s over. After all the trials and tribulations. After all the trauma and darkness. After everything both of them have been through. After all the love they have shared (in their own maybe cruel and unhinged way) … I can’t believe this is the last. But what a marvel it was !!! I loved every second of reading this book. So much so, that I try and take my sweet little time with it because I simply didn’t want it to be over too soon. But I couldn’t help but being devoured by it. The action, the fear, the political strategies to take revenge on those who had wronged them both. The spicy and the sweet moments between two broken souls making one whole !!! Their passion for one another was met with the intensity of their journey to power and vengeance. And Raziel … damn I fell even harder in love with him this time around !!! I might be in desperate need of a reread of the whole series !!! I can’t wait for more amazing stories by this same author !!!

“But I love you anyway. Completely. Desperately. However much I’m capable of, with this ruined soul of mine”

“There’s my Serpent Queen”

“Bound by blood. Bound by marriage. Bound by something that went deeper than either - the simple, terrifying, miraculous fact that they had chosen each other”

Review of advance copy received from NetGalley
June 6, 2026
Some series end and leave you satisfied. This one ended and left me absolutely wrecked in the best way possible.
The Serpent's Throne is the conclusion to the Bloodlines series and let me be clear, it delivered everything and then some. High expectations? Shattered. I went in ready and still was not prepared.
Nadi and Raziel. Together one last time. Fighting for revenge, fighting for power and somewhere in the middle of all that beautiful chaos, fighting for each other. These two are deliciously dark, completely unhinged and perfectly matched. They are morally grey at best and unapologetically monstrous at their core, and that is exactly why you cannot stop reading. They do not pretend to be good. They simply choose each other, again and again, in the most broken and breathtaking way possible.
Watching them grow across this series has been something special. By this final book they are more open, more vulnerable and more electric than ever. Their chemistry is scorching. Their love story is the kind that is impossible and forbidden and yet feels completely inevitable. I cried. I gasped. I fell even harder for Raziel than I thought possible and I did not think that was something I was capable of doing at this point.
The world building continues to expand beautifully here. Seeing more of the Wilds and the fae added such richness to an already fascinating world. The political scheming, the plot twists, the secrets layered throughout kept me completely locked in. I tried to slow down and savor it. The book did not let me.
This series is seriously underrated and if you have been sleeping on it, wake up. If you love dark romantasy with morally complex characters who make questionable choices and zero apologies, this is your series. Start from the beginning and clear your schedule because you will not be putting these books down.
What a marvel. What a ride. I already miss them

The story is a satisfying conclusion to the series, with some weak points. The pacing was off , but otherwise I loved the vibes of this mixture of Fae, Vampires and Mafia. I also enjoyed the twists and the relationship development.

Bloodlines #3 (now complete)

Thank you to Netgalley and Second Sky for an e-ARC of this book in exchange for an honest review!
-
Kathryn Ann Kingsley is a master at morally grey, sometimes morally black characters, and making you so invested in them and their growth. This whole trilogy was a ton of fun. They’re all short (300 or so pages per book), and they are quick with no downtime! Each book roles right into the next one. This book is the FINAL installment in the Bloodlines series.

Nadi and Raziel continue their alliance to try to bring down Raziel’s family. The Nostroms are clever and ruthless, and a lot of careful coordination is needed to make sure both Nadi and Raziel can leave the situation alive. Their feelings continue to grow for one another, and yet, they are both still a little unsure of the other - is the other person a friend, or are they waiting for their opportunity to betray the other? Honestly, the slowburn build of that trust was one of my favorite things about this book. The fact that we are in the final installment and Nadi nor Raziel are 100% sure about the other is delicious, but also realistic. While we are on book 3, the story has moved quickly and our main characters have not had a ton of time to develop their bond to one another. Their relationship is complex and not straightforward, making it easy to become invested.

This story took me on some interesting twists and turns that I did not see coming! Raziel and Nadi are well aware that they not make it out of this situation alive, but Kathryn Ann Kingsley really had me on my toes at multiple points in this book!

This whole series is a solid, fun read. It has a great blend of spice, complicated relationships, and a fast-moving plot. I had a blast with this entire series, and especially book 3!

Thank you to NetGalley, Kathryn Ann Kingsley, and Second Sky Books for the opportunity to ARC read this one. I was very excited!

⭐ 4.5 stars (rounded up)

What can I say? Second Sky Books are keeping me fed right now!

What a ride this was and what a way to end the trilogy.

Raziel… he’s an absolute dick, but I love him anyway. Kathryn Ann Kingsley has a real talent for writing villains who stay villains and I really enjoyed seeing that falling in love didn’t magically change who he was.

And Nadi? A complete badass queen. She’s resilient, determined and more than capable of holding her own, which made their dynamic all the more compelling. She didn’t need him, but she wanted him anyway.

The enemies-to-lovers romance was everything I wanted. While they’re clearly in love (at least in my opinion), trust doesn’t come easily and I loved that their relationship wasn’t suddenly fixed the moment they shared their feelings. Watching them develop even the smallest amount of trust felt much more satisfying than an instant happily-ever-after.

I really wanted to give this the full five stars, I genuinely did. Unfortunately, the events surrounding the first spice scene left me feeling really uneasy, and I couldn’t quite move past that. On top of that, I was left with unanswered questions during the final confrontation. I tried to suspend my disbelief about what Nadi was able to accomplish in her weakened state, but it just couldn’t do it.

That said, those issues weren’t enough to overshadow everything else. The twists kept me hooked, the pacing made it incredibly difficult to put down (I devoured this in 1 evening!) and I was completely invested in these amazing, messy, morally questionable characters.

Overall, I had a fantastic time with this trilogy, and it’s one I’ll definitely revisit in the future.

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.

Thank you to NetGalley, Second Sky, the amazing Noelle Holten and Kathryn Ann Kingsley for the ARC in exchange for an honest review.

Well. Kathryn Ann Kingsley really said “what if two deeply traumatised murderers fell in love and tried to burn the world down together?” and honestly? I ate up every second of it.

The Serpent’s Throne was such a satisfying conclusion to the Bloodline trilogy. Dark, violent, obsessive, romantic, unhinged — this series has always thrived in the morally grey chaos and this final instalment leaned fully into it. Raziel and Nadi are genuinely one of the most toxic-but-perfect-for-each-other couples I’ve read in a long time. Every interaction between them feels dangerous, emotional, and completely consuming. I was on the edge of my seat for most of this book. I just never knew which way the characters were heading next.

Raziel especially absolutely wrecked me in this one. Watching the line between Raziel Nostrom and the Serpent blur completely while still seeing how deeply, desperately he loved Nadi? Obsessed. Their relationship somehow became softer while still remaining feral and blood-soaked.

Some of my favourite lines:
“Two killers, wanting nothing more than to set it all aside, but knowing they never could.”

“We’re impossible.” “So we’ll be impossible. Together.”

“This was love in its truest, most terrible form—the willingness to destroy yourself for someone else’s sake.”

I loved the political manipulation, the lore reveals, the brutality, and the way this series never tried to sanitise who these characters are. They are monsters. They know it. And somehow that made the emotional moments hit even harder.

The ONLY reason this wasn’t a full 5 stars for me is simply because I’m not ready to let Raziel and Nadi go 😭

The Serpent and his little murderer own a piece of my soul now.
