The Sisters Who Mourn

To mourn is to burn. And they’re ready to set the world on fire.

After a devastating loss, Cyra, Rheanna, and Aella must pick up the pieces of their broken kingdom and face the coming darkness.

The kingdom of Linnosa teeters on the edge of war with the Cleansers no longer lurking in the shadows. The rebellion rises, their power fed by fear, betrayal, and something darker stirring beneath the surface.

As old loyalties falter and new ones form, the sisters must place their trust in unlikely allies, even those who once walked beside the enemy. Love is tested. Blood is spilled. And when Cyra’s daughter Hollin becomes a pawn in the war for magic itself, the cost of the crown becomes terrifyingly clear.

With monsters clawing their way out of the deep and the Oracle’s true intentions unravelling, the sisters find themselves caught in a web of secrets, prophecy, and impossible choices.

“What you face is a nightmare. But nightmares can be endured with the right poultice and a few good friends.” ”And perhaps, if we’re lucky, a stronger queen than most kingdoms deserve.”

More tragedy befalls the sisters, Cyra, Rheanna, Aella and Petra, as the prophecy that has told their fate starts to unfold. Cyra is the Queen but she and her sisters must work together to keep the kingdom safe from destruction. They are tasked with discovering their enemies protecting Hollin from the extremist group, strengthening their magic, forming anchors and allies, and healing from new and old wounds alike. To heal though, they must mourn their losses and walk through time to discover the meaning behind the foretold prophecy. Can Aella put aside her desire for vengeance? Does Rheanna learn her value? Can sisterhood transcend time and trauma? Can love blossom amid what stands ahead of them?

The Sisters Who Mourn is a medium paced story told from the sister’s POV. The world is easy to consume and just as compelling as the first book. As the plot thickens and the sisters start to pick up pieces of their shattered hearts you see the value of sisterhood. Now in this book it’s sisterhood but to me it holds true for any found family/relationship you hold dear to your heart. When Petra helps them from her spot in time, I got literal chills! I really enjoyed this story. In the authors words, although the world can be cruel and no goddess is without flaw…fire can kindle joy, water can heal, air can free, and earth can grow. Each gift demands choice.

A huge that you to Kayla Cosentio and Rattle the Stars PR for the opportunity to read and review this story. If you love fantasy romance, sisterhood, strong FMC’s, elemental magic, found family, dark prophecy, betrayal, and political motives give this series a try. “A sister waits in the shadows, Blood demands Blood.” Is the sister’s story over? or has it just begun? I sure hope we get more!!!

Kayla Cosentino has done really well with the second installment of The Sisters Who Were Promised Series. The stakes are higher in this book but she still takes the time to build on the relationships between the sisters, and show how each sister mourns the loss of Petra.

Each of the sisters have to learn to fully trust one another in The Sisters Who Mourn even as the dangers keep on mounting up around them. The bonds of sisterhood are certainly tested while they learn who they can and cannot trust. This is one of the things I really enjoyed reading in this book.

There are some new relationships for the sisters as well and I think each one is perfect for them. Atlas is a steady hand for Cyra and accepts Hollin as his own almost straight away. Their family unit is beautiful. Ripley is perfect for Rheanna. He gives her the strength to stand on her own two feet and realise that she also has a role to play. Kaelith is intriguing. I can’t tell if her and Aella will end up together, I hope they do though.

I would recommend this series to others and I’m looking forward to the next book in the series, which I’m hoping will come out very soon.

The Sisters Who Mourn was such a strong continuation of the series and delivered everything I hoped for after finishing book one.

Following Cyra, Rheanna, and Aella once again, the story raises the stakes in every possible way. The prophecy that has loomed over the sisters since the beginning starts unfolding in increasingly devastating ways, and the emotional impact of those events can be felt throughout the entire book.

One thing I really enjoyed was how the sisters continue to grow individually while also learning how to work together. Cyra may now wear the crown as queen, but protecting the kingdom isn’t something she can do alone. Watching the sisters strengthen their magic, build alliances, form anchors, and learn who they can truly trust added so much depth to the story.

The emotional side of this book felt different from the first one but just as powerful. There is more tragedy, more loss, and more responsibility weighing on the sisters’ shoulders. They aren’t only fighting external threats—they’re also trying to heal from old wounds while navigating new ones.

I especially enjoyed how the mystery surrounding the prophecy continued to unfold. As the sisters search for answers, uncover enemies, and work to protect Hollin from those who wish to use her for their own purposes, the story becomes increasingly difficult to put down.

The worldbuilding continues to expand naturally, and I appreciated that despite the larger scope of the story, it never became confusing. The multiple POVs remained easy to follow, allowing each sister’s journey to shine while still moving the overall plot forward.

What stood out most to me was the theme of grief and healing. To move forward, the sisters must first mourn what they’ve lost, and that emotional journey gave the story real weight beyond the fantasy elements.

If you enjoyed The Sisters Who Were Promised, I highly recommend continuing with this one. The stakes are higher, the emotions run deeper, and the prophecy becomes even more compelling as the sisters fight to protect both their family and their kingdom.

The Sisters Who Mourn picks up in the immediate aftermath of Petra’s death, and honestly, her absence hangs over every single page of this book.

What I loved most here wasn’t necessarily the twists or the expanding lore (though there are some genuinely compelling reveals), but the way the story lets grief reshape each sister differently. Cyra, Rheanna, and Aella are all mourning the same person, but they carry that loss in completely different ways — guilt, longing, anger, responsibility — and Petra’s presence somehow still feels palpable even when she’s gone.

That emotional core is what kept me locked in.

This series continues to shine brightest in its relationships. Not just romantically, but in the way it explores chosen family, loyalty, and the people who step forward to love each other in the aftermath of devastation. Watching Atlas fully embrace Hollin as his daughter absolutely wrecked me, and I loved seeing the sisters’ inner circle slowly expand beyond blood into something larger, messier, and deeply earned.

I also really enjoyed the progression of Aella’s arc in this book. After everything with her former lover, watching her slowly begin to open herself to connection again — even reluctantly — was one of the most compelling parts of the story for me. And yes, the tension with Kaelith was fantastic.

Thematically, this installment feels more transitional than book one, but I don’t necessarily mean that negatively. It feels like a story about aftermath. About survival. About carrying grief long enough to become someone new on the other side of it. And by the second half, I was fully emotionally invested in where these characters were headed.

Also, the ending? The implications of the final reveal and that last prophecy absolutely ensured I’ll be reading book three.

Overall, this was an emotionally effective continuation that deepened my attachment to these characters and expanded the world in interesting ways. If you loved the sisterhood, the aching devotion, and the emotionally messy relationships in book one, there’s a lot here to love.

This a beautifully haunting fantasy that blends political intrigue, elemental magic, and deeply emotional family bonds into a story that feels both epic and intimate. Kayla Cosentino crafts a kingdom drenched in grief and prophecy, where every choice carries the weight of generations, and every sister must decide what she is willing to sacrifice for the people she loves.

What stood out most to me was the emotional core of the novel. While there are monster attacks, royal betrayals, ancient curses, and dangerous magic woven throughout the story, the heart of the book is truly the relationship between the Voelbel sisters. Cyra, Rheanna, and Aella each carry their grief differently, and watching them slowly transform from fractured survivors into powerful rulers was one of the strongest aspects of the narrative. Their bond feels raw, complicated, and incredibly authentic.

The world-building is equally immersive. Linnosa feels alive with history, fear, and superstition, especially as the lingering curse and Selmana’s dark magic continue to shape the kingdom long after her initial act of vengeance. The elemental magic system adds another rich layer to the story, particularly as the sisters begin embracing their connection to fire, water, air, and earth. The mystical rituals and fae elements create an atmosphere that feels enchanting while still carrying an undercurrent of danger.

The Sisters Who Mourn by Kayla Cosentino was just as good, if not better, than the first book for me. This series keeps the momentum going so well, and the twists had me questioning everyone and everything the entire time. The plot was absolutely plotting 👀

One of my favorite parts of this series continues to be the relationships. I love seeing the bond between the sisters grow stronger while still getting to see their individual personalities, flaws, and wants shine through. The familial dynamics mixed with the romantic relationships make these characters feel incredibly real.

I also really appreciated the subtle exploration of grief throughout the story. Watching the sisters try to hold themselves and the kingdom together after such a devastating loss added a lot of emotional depth to the book.

I will say I slightly preferred the first book overall. I guessed some of the direction this one would take based on the ending of book one, and I felt like one major dramatic event wrapped up a little quicker than I would’ve liked. Even with that, I was completely hooked from start to finish and now desperately need book three.

Thank you to RTSPR and Kayla Cosentino for the ARC opportunity.💞✨

The Sisters Who Mourn by Kayla Cosentino is a strong second installment that builds beautifully on everything established in book one. Instead of losing momentum, this story deepens the emotional stakes and expands the world in a way that made it even harder to put down.
This book follows Cyra, Rheanna, and Aella as they try to hold together what remains of their kingdom while facing grief, betrayal, and growing danger. With monsters in the water, political tension rising, and Hollin at risk of becoming a pawn in a larger conflict, the story carries a constant sense of urgency without losing its emotional core.
One of the things I appreciated most was how much heart this book has. At its center, this is a story about family, loss, resilience, and the strength found in both the bonds we are born into and the ones we choose for ourselves. The characters each feel distinct, with their own voices, flaws, and desires, which made their relationships feel especially layered and compelling.
The writing leans more into plot and emotion, while still carrying a whimsical, immersive quality that keeps the story engaging. There were several twists that kept me questioning everyone, and the tension stayed high from beginning to end. I was especially invested in Cyra’s journey and found myself fully rooting for these characters as they fought for their future.
Overall, this was an engaging and emotionally grounded sequel that left me very eager for the next book in the series.

This second book in a planned series from author @kaylaconsentino stepped up the action and romance. I really liked the dynamic between Atlas and Cyra a lot. And the relationship between Atlas and Hollin is adorable. I also really liked the pairing of Ripley and Rheanna. I’m hopeful that there will be some more in-depth time spent with these couples to explore their connections in the next book. The antagonist group, The Cleaners, kind of remind me a little bit of the Guardians in Spark of the Everflame. I think I would have preferred the book to have each chapter from the first person perspective of a single character. I think that would have helped give the reader more connection to each of the sisters. The plot points sometimes seem to lack motivation and then are tied up quickly. I’d like to see more development in the next book for each beat of the plot. Overall, this is a solid second book in the series and I’m hopeful that the third book will expand the world and give us more of each sister with their partners.

The Sisters Who Mourn somehow took everything I loved about the first book and made it even more emotional, the stakes feel higher, the grief feels heavier, and the bond between the sisters feels even stronger as they fight to protect what’s left of their kingdom while everything around them starts falling apart, and I loved how each character still felt so distinct and layered with their own fears, strengths, and heartbreaks, the worldbuilding was immersive without ever dragging and the tension never really lets up between the monsters, betrayal, political chaos, and all the personal battles happening underneath it all, but what really got me was the heart of the story because beneath all the danger it’s still about family, resilience, and choosing each other no matter what, and that ending?? Kayla really had me sitting there staring at the wall because how do you end a book like that AGAIN, I’m way too emotionally attached to these characters now and I need the next one immediately.

I just devoured the second installment of this series in one day and I cannot get enough of these sisters.

We feel Petra in every room of this castle, she is with the sisters even though they were not reunited for very long. I even longed for her innocence throughout these pages! Kayla has such a way of gripping you by the throat and throwing you in the trenches of her world. I was enthralled by her writing and so invested in the character development of each sister. Their grief shaped them in different ways and they each found their way to work through it and found their strengths individually and within each other.

The feeling of sisterhood is so strong within this book and I loved every bit of it. The sisters are always with each other no matter what. Prophecy be damned. They slowly let others who proved their loyalty and love within their circle.

The ending? You got me again... I need book three now, please!!

There’s something quietly powerful about this story. It leans into grief, connection, and the weight of what’s left unsaid in a way that feels both emotional and grounded.

What stood out to me most was the atmosphere. There’s a heaviness to it—not overwhelming, but present enough that you feel it in every interaction and moment between the characters.

The relationships carry the story, especially the way emotions are expressed through actions rather than just words. It made everything feel more real and personal as it unfolded.

For me, this is a solid 4 ⭐ because while I really enjoyed the emotional depth, I found myself wanting just a little more in certain moments to fully push it to that next level.

What worked for me:
• strong emotional themes throughout
• character relationships feel authentic and meaningful
• the atmosphere adds depth to the story
• a story that lingers after you finish

Quiet. Emotional. Thoughtful.

Read this if you like:
• character-driven stories
• emotional, reflective reads
• themes of grief and connection
• slower, meaningful storytelling

Wow! The second boom is even better than the first one! So entertaining, full of magic, monsters, and the sister’s individual personalities and power were more explored.

Do I have a favorite sister? Not sure. I like each of them in different ways. The sisterhood fighting their emotions of grief and destiny, not only the enemies. Their bond is unique, raw and powerful. love that all the elements can be explored and we have a royal fae in this plot. And talking about plot.. what was that ending?!

Would love to see what is going to happen on the third book. What Kayla will come up with now!

Read this if you like character-driven stories, emotional and reflective reads, as well as themes such as grief and connections. This one is a meaningful slow storytelling.

Thank you Kayla Cosentino e Rattle The Starts PR for an arc copy of this book!

I this was an anticipated read for me. I read 𝗧𝗵𝗲 𝗦𝗶𝘀𝘁𝗲𝗿𝘀 𝗪𝗲𝗿𝗲 𝗣𝗿𝗼𝗺𝗶𝘀𝗲𝗱 (𝑏𝑜𝑜𝑘 𝟷) last year and was left in shambles. There was a strong emotional start to start and an even bigger one at the end. I’m still not over it. 😭

Going into 𝗧𝗵𝗲 𝗦𝗶𝘀𝘁𝗲𝗿𝘀 𝗪𝗵𝗼 𝗠𝗼𝘂𝗿𝗻 I was hopeful, that things wouldn’t continue to destroy me. HA I was wrong. I re-entered a world filled with grief and frustration. The political dynamics were very much still an issue, and a large obstacle. I loved that the sisters continued to keep their bond despite their situations. The way grief was explored while also sticking to the continuing plot seemed seamless. I think I appreciated that most. The sisters were confined to the grief and were able to continue on to grow.

Overall I loved this book as much as the first. It was filled with plot twists, sisterhood, political intrigue, and magic. ✨

Thank you so much Kayla Cosentino & RTSPR for the arc 🫶🏼

⭐️⭐️⭐️⭐️

The Sisters Who Were Promised was such an emotional fantasy read filled with sisterhood, betrayal, prophecy, and elemental magic. I loved watching the bond between the sisters slowly grow after years apart, and each sister felt distinct with her own personality and struggles. The mix of political intrigue, monsters, secrets, and family tension kept me hooked the entire time.

The emotional moments really stood out to me, especially seeing how grief and destiny shaped each of the sisters differently. The magic system was also really fun and added so much depth to the story. While some parts felt a little rushed toward the end, I was still completely invested and now need the next book immediately.

If you love:
✨ sisterhood
✨ elemental magic
✨ prophecies
✨ political intrigue
✨ emotional fantasy
✨ betrayal & secrets

…then this is definitely worth picking up!

**I was given this as an ARC, thank you Kayla for the opportunity.**

Okay, wow. Hello. Second book slump? Who is she, because it’s not this! The writing and layout got a bit better (and that’s not shade to the first), the characters are fleshed out, and the plot was PLOTTING.

Three sisters grieve the loss of one while trying to keep the kingdom afloat. It’s not easy, it’s not fun, and it’s definitely not cute. But this book takes you through a very subtle showing of the layers of grief, and I found that really interesting.

They’re finding love when they didn’t think they would, they’re working together, and AH I need the third please. I can’t wait to see how this story ends!

This book is the follow up to The Sisters Who Were Promised. Book one left us with heartache but also a sense of looming resilience and prophecies still yet to be realized.

This book takes us deeper into the world of grief and shows us exactly how grief can change us. It also shows the lengths to which grief can push us to.

Book one started our emotional journey, but book two definitely took us to the dark depths of it. How do you do what's right for the kingdom when your heart is shattered into a million pieces? That was the question the sisters had to deal with. With a war looming on the horizon, they have to figure out how to navigate what their heart feels and what their mind tells them they must do.

This was a solid four out of five star read for me.

Thank you to the author and Rattle the Stars PR for the ARC in exchange for an honest review.

I really enjoyed returning to this world in The Sisters Who Mourn. One of my favorite parts of the book was how deeply it explored each sister’s individual grief and how differently they each handled loss and everything happening around them. Their emotional journeys felt distinct and added a lot of depth to the story.

The sister dynamic continues to be one of the strongest aspects of this series, and I stayed invested in every POV throughout the book.

I did feel like the ending involving the oracle wrapped up a little too quickly for me, but overall, I really enjoyed this installment and that cliffhanger ending absolutely has me needing the next book immediately.

Book two somehow raised the stakes even higher, and I was obsessed from beginning to end.

The Sisters Who Mourn expanded the world, deepened the emotional tension between the sisters, and delivered even more betrayal, danger, and heartbreaking moments. The character growth in this installment was incredible, especially watching the sisters struggle with loyalty, power, and the weight of prophecy.

The pacing kept me constantly engaged, and the darker tone made everything feel even more intense. Every chapter felt like standing in the middle of a storm waiting for the next disaster to hit.

And that ending? RUDE. I need the next book immediately because this series has fully claimed my soul.

⭐⭐⭐.5 The Sisters Who Mourn: After the events of The Sisters Who Were Promised , the sisters must carry on. They are each dealing with the aftermath of the coronation in their own way. The pain of loss and betrayal is affecting each sister in ways they do not understand. Death and betrayal continue to pursue them at every turn. But, even with everything that has happened, there is still hope. New and very interesting characters are introduced in this book, and new adventures take place within the kingdom and the castle! The sisters continue to train and learn their magic after years of not using it. New love interests are found and even within the loss and grief, the sisters come out swinging! The ending had a surprise I wasn't expecting at all! Looking forward to the next book!

To mourn is to burn. And they’re ready to set the world on fire.”

The Plot: Dealing with the heavy price of prophecy, betrayal, and loss, the sisterhood is fractured. They must navigate their grief while the kingdom of Linnosa faces even deeper magical threats.

My Thoughts: This sequel completely raises the stakes. It’s darker, heavier, and far more emotional. The story dives deep into the aftermath of trauma and loss, and the emotional weight hits hard. When Cyra’s daughter becomes a pawn in the war against the Cleansers, the tension becomes unbearable in the best way. I loved how this book balanced action with such raw emotional depth. The family dynamics become even messier, more painful, and somehow even more beautiful.

A solid continuation of the TSWWP series. Kayla did an exceptional job changing the tone of the novel following Petra's death throughout each of the sisters' own journeys. I was so prepared for heartbreak during this novel and was still stunned in how it came around and was still not prepared enough for the emotional damage of dear characters. While this book definitely had it's fair share of heavy emotional burden and challenges, it still held a beautiful moment for periods of love, growth, and the power of family/sisterhood. I'm so glad each of the sisters was able to find a companion to rely on wholeheartedly, especially during their journey to the other side. I am excited to see where the story progresses and see this incredible family make Linnosa a better place for all.

The Sisters Who Mourn 🗡️

In the second book to The Sisters Who Were Promised, had me thirsty for more! The sisters must pick up the pieces of the broken kingdom and face what comes ahead. With new allies, love interests and spilled blood the path to the oracles true intentions becomes an obstacle everyone has been waiting for.

The Sisters who Mourn is available on Kindle unlimited and Amazon.

This book was emotional, high stakes, and action packed. The love between the sisters and the side characters is even more evident in this book the first. The found family trope was done so well in this book. I was so happy that Rheanna and Ripley’s relationship grew during this book and that she is starting to find a place where she belongs. The different ways each sister dealt with their grief was also done incredibly well. Everyone grieves differently and you could see that in each sister. All in all super solid second book!

I first wanted to say thanks to rattlethestarspr and Kayla for giving the chance to read this one early. 🫶📚

I’m literally obsessed with this series so far. The characters are 5/5 stars. The banter is so on point. I’m so in love with all the love interests. Also love the found family aspect, it makes you love the sense of loyalty.

I will forgive you for the ending but I did had a breakdown 😭

Most definitely will continue to read this series.

If you liked Throne of glass , you should check this one out!🥰📚

The second book in the series picks up right where the first left off. I liked that the bond between the sisters continued to grow stronger, as well as seeing more of their own personalities. I did enjoy the first book slightly more than this one.
The story was good but I just felt like something was missing the entire time.
I was pretty sure I knew how the second book would unfold based on how the first one ends. The “dramatic event” was resolved a bit too quick for my liking.

Thank you RTSPR and Kayla Cosentino for this arc opportunity. All thoughts are my own.

One thing I really loved about book 2 is how we see each sister kind of come into their own identity as they grow together in while navigating the aftermath of book 1.

One thing Kayla does really well is explore the relationships between characters, not just romantic, but deepening the connection between each sister. I very much like how this story has some romance, but it's not the main point of the plot.

I really hope we continue to see more of Holly's history regarding who her father is in book 3! Unless we'll never know, in which case I might throw a fit.

This is 100% the book that I’m going to be discussing with my therapist because this took me on one emotionally devastating ass ride and then forced me to experience all seven stages of grief. Life and the reality of the situation that these sisters find themselves in gets increasingly heavy in this installment of the series. There’s so much to unpack in this book and I don’t think the first book put into perspective how intense this story was going to get (in the best way possible.)

The Sisters Who Mourn picks up right after the first book, The Sisters Who Were Promised.

The sisters are trying to move forward after the betrayal and loss from the events of the first book. I enjoyed the sweet family interactions and the romantic relationships.

That being said I struggled to connect with characters this time around. Also the story was slow moving, I didn't feel like there was an urgency to deal with the Cleansers.

Overall I did enjoy the book, it just felt like something was missing.
