Since the first book A Cursed Son stole my heart with Astra's snarky banter and relatable inner monologue, I guess I can only describe my relationship with book two as madly and passionately in love.

Thank you Day Leitao and Netgalley for the eARC!

This book was filled to the brim with steamy spice, fiery romance and even some just-for-fun romps all while the story continues to surprise me with twists and turns, all while wondering "who is actually the villain(s) of this trilogy?" I loved every minute of it. We got to know beloved and hated side characters way more in-depth alongside learning more about the politics and ploys of the courts and major players. This series is full of heroines claiming their power to save themselves and those they love. Again, I LOVE IT. Astra is such a great FMC and I smile at how other characters talk about her. If you are looking for a great new romantasy series that is full of interesting characters, steamy romance and spice with a good serving of action, Remnants of the Fallen Kingdom will deliver! I am so excited for the final book A Devious Brother coming October 2025!

It was a strong sequel in the Remnants of the Fallen Kingdom series. Day Leitao wrote this strongly and enjoyed how they created a character development and how it was used its plots element. I enjoyed how good the enemy to lover romance was and how it blended in the fantasy element. I'm excited for the next part of this series, and from the characters and Day Leitao.

A Traitor Sister picks up directly from A Cursed Son, continuing the journey of Astra and Marlak in a world where fae politics, magic, and loyalties clash. This sequel broadens the scope with multiple POVs, deeper world-building, and a darker, more intricate plot—though some of that complexity also muddied the emotional clarity.

The multiple perspectives elevated the story by offering insight into various characters, and Astra’s growth -especially as she uncovers the truth about her training and begins to embrace her true identity- remains a highlight. However, I felt that the romantic chemistry didn’t match the intensity of the first book.

The political and fantastical stakes, including the ominous moving Crystal Castle and the threat of a false king, were compelling but didn’t always feel fully realized. One powerhouse scene, a confrontation between Astra and her sister in the castle, stood out for its emotional punch, even if overall pacing felt rushed at times.

Ultimately, while A Traitor Sister continues the saga satisfyingly, it doesn’t quite reach the heights I hoped for after A Cursed Son. Still, I’m invested in the series and optimistic about the next book redeeming the momentum. The concept remains strong and I’d recommend this series to romantasy and fae intrigue fans, it just leaves room for more depth in future installments.

I received an advance review copy for free, and I am leaving this review voluntarily.

4.5 stars

A Traitor Sister builds on the foundation of the first book, expanding its world with intricate plots, rich character arcs, and immersive world-building. While Astra and Marlak remain central figures, the story expands to a dynamic cast whose interwoven narratives add depth and intrigue. Themes of magic, power, and deception unfold against a backdrop of political intrigue and mystery.

As the focus shifts toward secondary characters, fresh emotional complexity emerges. Azur’s gruff exterior hides surprising depth, making him an unexpected favorite, while Renel’s motivations reveal complexities beyond simple villainy. Astra’s journey to master her magic and uncover her lineage is compelling, though some may miss the earlier intimacy between her and Marlak. Unpredictable twists drive the plot toward a heart-stopping climax, keeping readers on edge, while expanded perspectives enrich the narrative, weaving an intricate story where every thread connects in unexpected ways.

The world-building remains impressive, with vivid landscapes, an evolving magic system, and intricate court politics heightening the tension. Long-hidden secrets unravel, fragile alliances shift, and betrayals emerge, culminating in a twist-filled ending that lingers beyond the final page. Careful character development balances bursts of action, accelerating into a whirlwind of revelations at the end, with intrigue, emotional relationships, and dynamic storytelling keeping the pace consistently engaging.

Overall, A Traitor Sister is a captivating sequel, blending intricate magical lore, sharp political intrigue, and multi-layered character development. Expanding beyond the central romance, it introduces a rich ensemble whose perspectives add emotional weight and unexpected turns. With layered storytelling, high-stakes conflicts, and immersive world-building, it delivers a thrilling journey that leaves readers eagerly anticipating the final book.

This review is long overdue. I finished this weeks ago. Oops!

Book two adds more POVs and more spice! However, the storyline seemed to drag and I found it hard to push through til the end. I definitely liked book one better.

After devouring the first book in the Remnants of the Fallen Kingdom series in no time at all, I wanted to continue reading as soon as I finished and was so excited to see how the story would continue. But this book definitely surpasses the first book by far. It pulled me right back into the story and world and didn't let me go until the end, which is why I couldn't put this book in the series down. The book is even more compelling and the world even more immersive, so I couldn't stop turning the pages. Also, the writing style, which is vivid and detailed, written in a suspenseful way, keeps you hooked. You also get to know and understand the characters better and are able to form an emotional bond with them. The twists and turns in the story are fantastically written. A series I highly recommend! I can't wait to read the next book!

Ohhh I liked that even more than the first one!!

Whilst I liked the first book it was very Astra and Marlak focused, but hinted at all these amazing other characters and I was so happy to get so many more PoVs this book and parallel stories.

👑💜👑💜

Premise:
Continuing on from book one, Astra has been kidnapped by Renel, the acting king of the Crystal court and Marlak’s brother. Whilst Marlak is trapped in his prison.

Meanwhile after Ziven and Tarlia are almost killed in an assassination attempt, they team up with Marlak’s allies to break into the Crystal court and rescue Astra.

But different alliances start to form! Tarlia finds herself plotting. And Marlak finally see a way to save his lost sister.

👑💜👑💜

So this book kind of has 3 parallel storylines, and hands down my favourite was our new foursome squad. Mostly because I just adore Tarlia and her attitude and absolute lust for life (and other things). Plus I fall for all the same men as her 😂 I loved her new developing relationship as well and the spice was hot 🔥

The Marlak and Ziven storyline was also a fun one! I loved their quest and their bonding. Ziven remains a loveable idiot at times and I wanted to shake him at the beginning with the Tarlia situation. I hope he sorts himself out in the next book and ends up with a fun storyline.

Astra’s journey was also good, but I preferred the other two! Although her storyline had some good twists! Oh wow that ending! I thought the book was heading for a happy ending and then we got all those cliffhangers! I’m excited for book 3 with all the reveals 😱😱

All in all, a fun addition to this series and will definitely read the next one.

I was up all night devouring this book. I loved the first book to this series so was excited for the chance to read the ARC. You get more POV’s that helped build the story up and of course the main characters Astra and Marlark. Book does leave you on a cliffhanger but that’s what a good series does… leave you wanting more. Thank you so much for the arc NetGalley!

just like with the first book, this one was amazing as well! truly everything i wanted and maybe even more

Thank you for giving me the opportunity to read this ARC of ‘A Traitor Sister’.

I loved the first one & absolutely couldn’t wait to read the second. It was just as good & didn’t disappoint!

This book is tailor-made for readers who revel in a captivating fusion of high-stakes fantasy and passionate romance. It is especially suited for those who are drawn to tales of heroines who unearth their hidden power amidst a whirlwind of magical chaos and intricate, multifaceted relationships. The story will immerse readers in a world where the stakes are high, the magic is potent, and the romantic entanglements are as complex as they are passionate. Readers who enjoy stories of self-discovery, resilience, and the power of love in the face of adversity will find this book particularly appealing.

This was a fantastic second book, what a rollercoaster. It completely swept me up away into the world. I loved getting more POVs and the writing style was excellent. Awesome world building and magic system, I would highly recommend this to all romantasy readers.

Thank you so much to Netgalley and the Publishers for this ARC opportunity, I had a wonderful time reading this A Traitor Sister.

This was a really interesting expansion of this universe!
The last book ended on a huge cliffhanger, and this one doesn't slow down. The story flowed without really stalling, and the ending left me ready for the next book (but I won't spoil it!). At first, I was confused when I saw that we got a pov from almost every main character (That wasn't the case in the first book) but I found it really added to the story and enhanced the worldbuilding. I sung these characters' praises in my first review, and I still love them. Astra was especially close to my heart throughout the story-- watching her grow away from her indoctrination and into her own person made me so happy. I loved that we got to learn more about the fae and the fae courts, many things that didn't make sense to me in the first book are easier to understand now. Overall, I'd recommend this one to fantasy lovers.

A Traitor Sister elevates the series with heightened stakes, deeper magic, and astonishing revelations. Astra battles to master her power and save Marlak, while the Crystal Castle hurtles toward destruction. New perspectives introduce fresh intrigue, broadening the world and its complex alliances. I loved how the relationships developed; friendships, betrayals, and unexpected romances kept me engaged. The pacing is relentless, and every twist left me breathless. The emotional depth of the characters’ struggles made this book impossible to set down. Day Leitao expertly balances action, court politics, and romance, creating an unforgettable read. I’m eagerly looking forward to the next installment!

A Traitor Sister by Day Leitao is a wild rollercoaster of action, emotion, and romance that kept me hooked from start to finish. I loved getting more insights into Astra and Marlak, as well as exploring new characters and their motives. The mix of magic, danger, and unexpected alliances makes this sequel a thrilling ride. Can’t wait for book 3!

A Traitor Sister was such an enjoyable read—a total whirlwind! The world-building had me wanting to take notes just to keep up. I loved the vivid imagery of each land and the unique challenges the characters faced there. The magic system continues to impress me, and the relationship dynamics constantly kept me guessing. Just when I thought I had everything figured out, another twist was thrown my way. I’m still not entirely sure who’s friend or foe!

There was so much to love about this book, but I did feel a bit all over the place with the multiple POVs. While each perspective was interesting and added depth to the story, I sometimes found myself eager to get back to the POV I had just been immersed in.

Somehow, this book felt both long enough and too short at the same time—I’m just not ready to leave this world and these characters! 🥰

Thank you NetGalley, Victory Editing, and Day Leitao for this ARC!

Rating: ⭐️⭐️⭐️⭐️✨
Spice: 🌶️🌶️

Wow. Usually, the second book in a series has a huge lull to it but I REALLY enjoyed this one! We get POVs of our well established FMC, Astra, and MMC, Marlak, but we get multiple new POVs of side characters. One thing that makes a good fantasy book great is well developed side characters and their respective relationships, and Day totally delivered on that part!

The ending of book 2 was pretty jarring so I am fully invested and ready for book 3!!

Thank you so much to Day Leteiao, NetGalley, and Victory Editing for the eARC!

A great sequel! Loved all the PoVS and romantic branches we’d got in this one. Also more details of the inner workings of court that we didn’t get in the first. Super fun read!

I didn’t ~ love ~ the first book in this series but I loved this one! The POV Marlak added absolutely changed the game for me. There’s nothing wrong with Astra or her POV, but the first book felt very stagnant to me, so this new consistent POV was a game changer for me.

I also felt like this book was a lot more exciting than the first. To me, the first was a lot of sitting around and waiting for something to happen, but this one changed the game. We’re in the swing of things right from the first chapter, setting the pace for the majority of the book.

Back to the POVs for one second. I loved how the POV break wasn’t always at the start of a new chapter. For some chapters, it made a huge difference to me that we switched from Astra to Marlak right in the middle of it. What I didn’t love though was how many times this happened with so many different characters. I liked our new characters, but I wasn’t the world’s biggest fan of all their POVs. There was a lot to keep track of sometimes and I got a bit lost.

I’m excited to see what else happens in this world.

Thank you very much to NetGalley, Victory Editing, and Day Lietao for an ARC of this book. All opinions are my own and in no way influenced my review.

Rating: 4.5/5

The novel's blend of magic, romance, and political intrigue kept me eagerly turning pages. The slow-burn enemies-to-lovers dynamic between Astra and Marlak is particularly well-executed, adding depth to their relationship. The author's writing style is engaging, making it hard to put the book down. Thank you to Netgalley and the publisher for this ARC.
