The phoenixes are dying. The kingdom that worshipped them has fallen. When rebel spy Aliwen steals a sentient grimoire, she uncovers a truth the witches buried. The curse that destroyed the phoenixes was never meant to be broken.

But hidden within it is a single flaw.

Her.

On the run with the rebel leader who believes she holds the key to reclaim their kingdom — and hunted by an enemy Rider whose fire would destroy her with a single touch. Aliwen has the twelve nights of Yule to unravel the spell that reshaped kingdoms.

Or burn with it.

Hello and welcome!

I’m Isla Lockwood and I write dark, immersive romantasy inspired by folklore, mythology, ancient magic and the wild beauty of the winter.

My stories feature cursed phoenix riders, sentient books and the wonder of midwinter - where myths still walk among mortals. I draw inspiration from the traditions of Yule, winter folklore, Celtic and Germanic mythology. And I'm obsessed with the idea that long ago stories were told around fireside on the darkest nights of the year.

Growing up in a family who loved books, antiques and storytelling, I’ve always been drawn to myths, legends and the objects that carry stories through generations. Before becoming a novelist, I worked in publishing for a little bit before moving into events. But books have always been my whole personality either reading or writing them.

When the Sky Burns is my debut indie published romantasy novel, and the first book in the Skyworld series. It took nearly three years to get to this point and it is my love letter to the atmospheric, romantic and just-the-right-amount-of-dangerous books that I adore to read. And this is just the beginning - things will get darker and more dangerous as we go on!

I live in a medieval cottage in a tiny village in Suffolk with my family, where you’ll usually find me trying to convince my two overly energetic labradoodles that the shadows in the garden are not, in fact, invading armies.

If you want to join the Skyworld and learn more about it's characters (and the hot phoenix riders!) visit my website and for bonus content and upcoming info on my books and events join the newsletter.

Hold on tight - this is going to be quite a ride!

"I was forged in destruction, and I'll rise like a roaring fire."

Cursed phoenix riders, ancient magic, morally grey characters, and a winter atmosphere dripping with danger. This was such an intriguing premise, and so refreshing to read. One of my favorite things about this book was the way the author incorporated folklore into the very foundation of her storytelling. The folklore surrounding the twelve nights of Yule added such a unique spin to the story. I loved how the winter traditions, ancient curses, and supernatural elements created an atmosphere that was enchanting yet mysterious. The author did an amazing job at capturing the folklore but still allowing the story to stand on its own as well.

Aliwen, our FMC, was definitely my favorite character in this story. She isn't a character who has everything figured out and that makes the journey even more interesting. Her circumstances as a slave, rebel, and spy force her to question what she knows, whom she can trust, and what she is willing to sacrifice. Aliwen is a powerful and resilient badass and I love the fact that even though she is a pawn in someone else's story she is also the person capable of rewriting the ending.

Then the author comes in and hits us with that ending.....I am heart broke for how long I might have to wait to figure out what happens next because Isla I have questions!!!

I received an advance reader copy of this book to read in exchange for an honest review as part of the book tour hosted by Random Things Tours.

When the Sky Burns is the first book in a new christmas romantasy series with phoenixes!
We follow the POV of Aliwen who has been hiding in plain sight under a cloaking spell that changed her appearance to get access to the library of magical books that are locked away from general access.
Her and her two cousins have been part of a Resistance movement to take back the kingdom their traitorous uncle stole from them and ruined with his rule. When Aliwen is confronted at the library by a man with a familiar voice who is after taking a codex to benefit the cursed phoenixes and their riders, her journey takes an unexpected turn and I was left open mouthed at the ending of this book by a twist I did not see coming!
Aliwen is an intriguing character with much resilience and steel to her spine and I cannot wait to find out more and see what else she reveals of herself in the next book.
If you love dragon riders and fantasy books you need to read this and fall in love with phoenixes next just like I've done!

Thank you for the ARC!

Cursed phoenix riders, ancient magic, morally grey characters, and a sentient book? Yeah, this was absolutely going to get my attention.

One of my favorite things about *When the Sky Burns* was the atmosphere. Isla Lockwood really leans into the dark, wintry setting, and I loved how the twelve nights of Yule created this constant sense of impending disaster. The mythology surrounding the phoenixes, their riders, and the ancient curse was easily one of the strongest parts of the story.

Aliwen was such an interesting FMC. She's angry, determined, and driven by revenge, but she's also navigating a world where practically everyone seems to have their own agenda for her. I particularly enjoyed the complicated dynamics between Aliwen, Aster, Kit, and Torran. There are so many questionable loyalties, buried secrets, and morally grey decisions that you're constantly wondering who can actually be trusted.

I also appreciated that the fantasy plot wasn't sacrificed for the romance. The slow burn is genuinely slow, and while I enjoyed the romantic tension, I would have liked a little more development in some of those relationships. The pacing also felt uneven in places, particularly when the story was juggling its worldbuilding, political intrigue, and character dynamics.

But the phoenix lore? The sentient grimoire? The underlying themes of power, control, and reclaiming your own agency? Those were the elements that really worked for me.

Overall, a solid four stars! This is a great pick for readers who love their romantasy atmospheric, their characters morally questionable, and their magic tied to something much bigger than a love story. I'm definitely curious to see where Lockwood takes this world next!

Review of advance copy received from Author
October 14, 2026
Thank you Author Isla Lockwood for allowing me the enjoyment of reading and reviewing this ARC.

And also for making me second and triple guess every character in this book at every turn. 25% in I'm over here trying to figure out who this FMC is, who her next love interest is, who's on who's side, where's the good guys (are there any?), should I be mourning for these deaths?, and who in the heck is gonna torture who next.

I AM NOT MAD ABOUT IT. 😆 It's an all out war game between royalty & their kingdoms, and they don't play nice.

This Yule fantasy will make a great winter read. I love the way the book is set up. You have 12 sections with 2 to 4 chapters in each that could be read the 12 nights leading up to Christmas!! That's if you can stand to close the book and wait a night... good luck!! Because once that 50% mark hits, its on and our FMC is gonna change the world.

I need more!!!!!

ARC REVIEW

This was a fun read with some genuinely interesting worldbuilding, but I never fully connected with the story the way I wanted to. 👀

The book starts off fast, and I’ll admit I was a little lost in the beginning trying to keep up with all the rune magic, lore, and unfolding conflict. The magic system is unique, though, and I especially loved the concept of sentient books! The phoenix riders and the history surrounding them also intrigued me, and I enjoyed learning more about the world as the story progressed.

The 12 nights of Yule, the curse, and the different magical elements kept me curious, even when the overall plot felt a little slow. There were moments where things dragged, and I found my attention wandering. I also guessed the end twist fairly early, which took away some of the impact for me.

As for the romance… I wanted to love it more than I did. 🥹 There was tension, and a few moments definitely had me intrigued, but I never fully bought into the relationship. I wanted more development and a little more oomph.

Overall, this was an interesting fantasy with unique magical concepts, intriguing lore, and some fun moments. It just didn’t completely pull me in, and the predictability left me feeling a little underwhelmed by the end.

I’m glad I gave it a read, but I’m not sure I’ll be continuing the series!

My Review✨
From the beginning, this book was PACKED with adventure and action. No slow build up for the first half, no overly intricate world building that required referencing lists and maps repeatedly or getting confused about locations/families/feuds/etc. Don’t get me wrong - there absolutely was world and lore building as both are VERY relevant to the plot as a whole. And also don’t get me wrong - the world and lore building WAS detailed. But all of the aforementioned were done in a way that flowed effortlessly along WITH the plot and this, in my opinion, made this book INCREDIBLY easy to read and keep up with.

As far as the characters and the plot itself go? 10/10, no notes, literally chef’s kiss. There will be characters you love to hate, characters you hate to love but can’t help loving anyway, and an INCREDIBLY strong, feisty, determined, take no shit from nobody (even when she’s in some VERY precarious/dangerous situations) spitfire of an FMC that you will LOVE. And if you don’t, pure entitled to your opinion…but your opinion is WRONG (jk of course, I FULLY respect everyone’s right to have their own opinions even if they differ from mine).

There IS some spice in the book for those who are spice friendly but the scenes do not overshadow the plot and whilst detailed AND hot 🥵, they are very minimal. But trust when I say that the plot is so enrapturing you honestly probably won’t even notice (I certainly didn’t).

This is, hands down, going to be one of those books that I am going to recommend to anyone and everyone I humanly can because it’s just THAT good and that hard to forget.

ARC Review for When the Sky Burns by Isla Lockwood:

'Whatever this Rider knew, it wasn’t my true identity. Every man I’d met in the Barren Lands since my capture at thirteen sought to break my will, but instead they’d forged me into a weapon.'

Ariwen and her cousins have risked everything to become free. Split up, Ariwen sets out to find the others, to regain an army to support Thorn's reclaiming of their kingdom from the men who had taken it, and to gain vengeance on those who deserve it. Along the way, secrets are revealed, loves rekindled and fires set to bring the world to its knees.

'The books in those rooms had both opened my mind and made me feel even more imprisoned. What I had learned had changed me, and as I taught others, including my cousins, it had changed them too.'

This is phenomenally accurate. Books have a way of soothing the soul, firing the senses and bringing together diverse groups of people. This tome is no different. I especially loved the relationships that the actual books in the story have. They help out, they vibrate with enthusiasm, the warn of danger. They are their own characters, have their own personalities, and hold the same importance in their world as books hold in ours today.

The characters and world building are top tier. They elicit responses through how vividly they are rendered in your mind as you read. It is so well done that you can see the steam, smell the ash and taste the snow. Each character, each land, breathes life into one another. They dance in your mind further enlightening as the pages turn.

“By the end of this, I’ll be your reckoning,” I vowed.

Everything in this story is so relevant to the world we live in today. The abuse, assault and rape of women by men who consider them lesser is ever present. But so is the rage that fills us, and the unrelenting fight to free ourselves.

I want to thank the author for allowing me to be an early part of this book's journey and for trusting my opinions of it. Isla, you have created worlds and characters that I truly can relate to, and see it's relevance now and for years to come. I'm here for every second of it.

4.5 ⭐️! What a great book! Thank you to the author for the opportunity to ARC read this book.

Secrets, forbidden love, phoenixes, and a woman caught between the people she loves and secrets she’s spent years running from. When the Sky Burns was such an emotional read!

Aliwen is a feisty and strong FMC, her life turned upside down by the fall of her kingdom and the years she’s spent fighting to reclaim what was lost. Once part of the royal family, she’s now a rebel with a talent for restoring magic to books and a past full of secrets. When her search for answers leads her back to Aster, the man she loved who she thought was in prison, things get complicated very quickly.

And Aster… you guys, ASTER! His history, the longing, the tension, the protectiveness! Three years apart, feelings that never went away, and too many secrets between them. These two had me in a chokehold. The things they can’t say, the truths they’re hiding, and the way they still are drawn to each other and protect each other? Give me more!!

This book has political intrigue, phoenix lore, cool magic systems, tension, and the countdown of the twelve nights of Yule, creating a moody and magical vibe that had me completely hooked. There was something very moody and romantic about the setting and the lore in this book that I absolutely loved. The forced proximity in this book was delicious! I could reference a scene, but I’m not gonna do that. You’ll know it when you get there!

This book has everything I love about romantasy: a complicated second-chance romance, secrets upon secrets, a fiercely protective love interest, political scheming, magical lore, and an FMC who has to decide what she’s willing to sacrifice for the people she loves.

This book has:

Morally Grey Characters
Cursed Phoenix Riders
Second-Chance Romance
Slow Burn
Forced Proximity
One Horse
Captive x Captor

I’m so ready for more from this world, and to see what’s next for Aliwen, Aster, & Torran. Oh and more Kit! He’s like the sassy sidekick that I hope to get more of in book 2!

i was really intrigued by the premise of When the Sky Burns. there was so much here that sounded right up my street, and i genuinely think the core idea is really interesting.

unfortunately, the execution didn’t quite live up to the premise for me. this is very heavy on the world building, particularly early on, and there were points where i found myself confused about both the magic system and the politics of the world. there’s a lot of information to take in, but i didn’t always feel like i had enough grounding to properly understand how everything fit together.

my biggest issue was the repetitiveness. i think this really needed another editorial pass because the repetition became genuinely distracting. certain phrases crop up over and over again “and there it was” being one that particularly stood out - alongside repeated actions, there was a particular chapter where Aster tightened his arms around Aliwen’s waist seemingly every single paragraph. there are also SO many ellipses, especially in the dialogue, that after a while they made conversations quite fatiguing to read. once i noticed these things, i unfortunately couldn’t stop noticing them.

that said, there were definitely things i enjoyed. the action sequences were fun, and i really liked the mythology surrounding the phoenixes and the curse - that was probably the strongest part of the story for me. i can tell that Isla has put a lot of thought and love into this world. i also enjoyed Aliwen’s relationship with Aster, although i finished the book still not entirely sure whether he’s being positioned as the main love interest for the series or whether something else is coming 👀

overall, this was one where i loved the concept more than the execution. there’s enough here that i’m curious about where the story is going, though, and i enjoyed it enough that i will pick up the next book in the series. i’m hoping that with the world now established, the sequel can focus more on developing the characters, relationships and story and hopefully a smoother editing process that crops out the silly little things that hamper the experience.

I was gifted a copy of this book by the author in exchange for an honest review.

When the Sky Burns is a fast-paced, addictive story that’s perfect for the -ber months! The writing is immersive and easy to follow, and the worldbuilding is exceptional. It never feels like an info dump because the author does a fantastic job of introducing us to the universe naturally.

The characters are morally gray, and the twists and turns will keep you guessing their next moves. If you enjoy fantasy with high stakes, a compelling romance, and a layered world built around a unique magic system, this book is for you!

What an interesting story! Nonstop from the start, with intriguing folklore and magic, characters I don't know if I should trust or root for or love or hate, and a slow burn romance that was delicious. This was an intense read as I couldn't slow myself down because I had to know where it was going as Aliwen worked so hard to free herself. I enjoyed this story so much and will absolutely be reading what happens next with bated breath!

I thought dragons had a permanent residence in my fantasy loving heart but Isla Lockwood came along with this book and said: “Move over, we have giant magical birds now.” And honestly? Fine. I surrender. Give me them all!

From the very beginning, there is something happening. This is not a book where I have to patiently wait 40% of the story for everyone to stop standing around explaining the world to me. The action, danger, magic and mystery are sprinkled throughout in a way that kept me turning pages because I genuinely wanted to know what disaster was waiting around the next corner and there are quite a few.

Aliwen was absolutely my kind of FMC. She is angry, determined, stubborn and carrying enough rage to power an entire city. LOVE IT! She has every reason to want revenge and watching her navigate everything thrown at her without becoming a helpless damsel was SO satisfying and refreshing. She doesn’t just sit around waiting for someone else to fix her problems. Girl has plans. Questionable plans sometimes? Absolutely. But plans.

And then there is Aster. 👀

I spent a good chunk of this book trying to figure him out and honestly, I enjoyed every second of it. There is a layer of mystery around him that made me want to keep digging, especially as more of his connection with Aliwen came into focus. Their relationship gave me that delicious combination of tension, history, hurt and please just TALK TO EACH OTHER frustration that I live for. The romance also worked for me because it didn’t completely swallow the fantasy plot. There is yearning, chemistry, kissing and a little spice but I never felt like the story was using romance as an excuse to forget everything else happening. I was here for the magic, the revenge, the phoenixes, the danger and the emotional damage. The romance was simply another way to make me emotionally unstable.

Kit and Torren also deserve a mention because I had approximately many different feelings about them. Some characters you love immediately. Some you want to shake. Some you are suspicious of while simultaneously thinking, hmmm… tell me more. These two definitely kept things interesting.

The Yule setting was another favorite for me. There is something about winter, old magic, curses, witches, ancient lore and a countdown toward something potentially catastrophic that just scratches the fantasy itch in my brain. Add phoenix riders and a curse involving dying phoenixes and their bonded riders and suddenly I have forgotten every responsibility I have ever had.

🫠 The Emotional Damage Department… Aliwen and Aster definitely put my emotions through the washing machine. There is so much history, loss, anger and unfinished business between the characters that I was constantly waiting for another little piece of the puzzle to fall into place. I liked that I wasn’t handed every answer immediately. It gave the story enough mystery without making me feel completely lost.

And that ending?

Ma’am.

EXCUSE ME?!

I would like to formally request the next book immediately. Preferably yesterday. Thank you.

🌶️ Spice Check: There is some spice, but this is definitely not a romance where the spice takes over the plot. The romance is much more about tension, yearning, emotional connection and the complicated history between Aliwen and Aster.

Final Thoughts: This was such a fun fantasy romance read for me. It’s adventurous without becoming overwhelming, magical without drowning me in complicated lore and emotional enough to make me stare at my Kindle like it personally betrayed me.

Release Date: October 15, 2026

Huge thank you to Jess Beyond The Pages and Isla Lockwood for giving me the opportunity to read this eARC ahead of release. I had such a fun time getting lost in this world and I am absolutely going to be watching for what comes next.

“I was forged in destruction, and I'll rise like a roaring fire.”

When the Sky Burns by Isla Lockwood is absolute perfection. There’s so much going on in this Yule folklore romantasy, you can’t help but be completely enthralled in the story.

“They forgot that the most powerful rebellion is committed in silent acts —ones that go unnoticed until it's far too late.”

Aliwen has lots of secrets - she’s a rebel, she’s a spy, she’s a reader of magic books. And she’s lost royalty from a conquered kingdom. When she dishes out justice of her own, she’s on the run. Aster was leading the rebellion, but now he seems to be entrenched with the Celts - so now where do his loyalties lie?

“It was somewhere in the mines that I realised I had forgotten what I was fighting for. But I never forgot you."

Whew, we’re dropped right in the middle of the action. It’s fast-paced, so I was constantly guessing what was about to happen. Aliwen has so many layers, I was constantly surprised. Aster has so many layers to him, I was always guessing what he was up to. But ughhhh the yearn, even without his POV, his desire for Aliwen is palpable.

"I need you to know that in another life it would've always been you. It is always for you.”

I absolutely loved the folklore, the winter magic, the phoenix mysteries, and then we have sentient books as well? I will also add that I spent way too much time trying to figure out who the ”good guys” were. Ha, I don’t know that there are any. But only shades of grey.

“We are, after all, what we endure... what we survive.”

If you are looking for your next fantasy read with winter folklore vibes, political intrigue, lost princesses, a unique magical system, and the slowest burn romance, pick this up!

“Whatever happens, from this point on, you Do. Not. Flinch.”

Thank you to the author for providing this book for review consideration - All opinions are my own.

📚 When the Sky Burns – Isla Lockwood 🔥🎄

A Christmas romantasy with phoenixes, ancient curses, dangerous magic and a countdown through the twelve nights of Yule? Yes, please!

I really enjoyed this one, and that ending has left me with a serious book hangover!

Aliwen isn't your typical fantasy heroine. She's a bookbinder and restorer who finds herself caught up in something far bigger than she could ever have imagined. What I particularly liked about her was her determination to save her cousins, even when the odds were stacked against her.

The characters throughout have you love to hate, hate to love - whichs ones, you'll have to read to decide!

The story brings together dying phoenixes, a mysterious sentient grimoire, rebellion, secrets and a curse that threatens far more than anyone realises. There's plenty of danger and intrigue, with a slow-burn romance woven into the wider story rather than taking over the plot.

I also enjoyed the twelve nights of Yule setting. It gives the story that wintery, magical atmosphere while adding a real sense of urgency as time begins to run out.

But can we talk about that ending?! 😱

There were hints scattered throughout the story, and looking back, I can see how cleverly they were placed. Yet somehow, I still didn't see that huge twist coming! I absolutely love it when an author manages to surprise me like that.

And now I'm left desperately needing book two because I have QUESTIONS! 😂

If you enjoy strong heroines, ancient magic, dangerous loyalties, slow-burn romance and plot twists that catch you completely off guard, this is one to add to your TBR.

First I want to thank Isla Lockwood and Jess Beyond the Pages for the eARC.

Are you tired of all the fantasy books that are starting to feel the exact same?? If the answer to that question is yes then I highly recommend picking up this book!! It had me completely hooked from the very first chapter.
This is such a fast-paced action packed fantasy. You still get your world building and all of the lore but without the slow lull.

In this you have our FMC Aliwen who is a badass independent woman full of feminine rage. She has been unfortunately captured but she is still determined to escape and to right all the wrongs that have been done against her brother and the Annatalia people. Then you also have our cast of morally gray phoenix riders Kit and Torran that I can’t wait to get more of. I think there is so much more to the two of them than what we have gotten so far. I am hoping we get more answers about what really happened with them and her brother Lex. Then you get our MMC Aster who is absolutely swoon-worthy. They had a relationship when they were both younger up until he disappeared. We find out that Aster has gone his whole life trying to protect Aliwen in any way he can even if she doesn’t know it.

I also have to say one of my favorite parts that I did not expect was the sentient books which added to the complete uniqueness of this book. I loved that she broke up the Yule nights chapters and went over what each Yule night was again before starting the chapters that take place during that night. I seriously could not put this book down. Also after that ending I have quite a few questions and can not wait for book two!!!

I know we all love a dragon fantasy, but When the Sky Burns proves that phoenixes are just as fierce, magical, and badass 🐦‍🔥

I loved the worldbuilding in this one! An ancient curse is believed to be behind the dying phoenixes, their bonded riders going mad, and war on the horizon. Everything gets more chaotic as we follow the 12 nights of Yule, the most dangerous time of year. And there are sentient books! 📚 This was such a cool addition to the story and I love that they actually served an important purpose.

𝙃𝙚 𝙝𝙖𝙙 𝙤𝙣𝙡𝙮 𝙚𝙫𝙚𝙧 𝙗𝙧𝙤𝙪𝙜𝙝𝙩 𝙚𝙭𝙦𝙪𝙞𝙨𝙞𝙩𝙚 𝙥𝙡𝙚𝙖𝙨𝙪𝙧𝙚, 𝙘𝙤𝙪𝙥𝙡𝙚𝙙 𝙬𝙞𝙩𝙝 𝙝𝙚𝙖𝙧𝙩𝙗𝙧𝙚𝙖𝙠𝙞𝙣𝙜 𝙡𝙤𝙨𝙨. 𝘽𝙪𝙩 𝙄 𝙝𝙖𝙙 𝙖𝙡𝙬𝙖𝙮𝙨 𝙞𝙜𝙣𝙤𝙧𝙚𝙙 𝙖𝙡𝙡 𝙨𝙚𝙣𝙨𝙚 𝙬𝙝𝙚𝙣 𝙞𝙩 𝙘𝙖𝙢𝙚 𝙩𝙤 𝙝𝙞𝙢.

As for the characters, our rebel FMC, Aliwen, was my favourite - full of feminine rage and always plotting revenge. Kit had me smiling every time he was on page. Torran might be a villain but the kind I want more of… and maybe even see a redemption arc in future? 👀 And Aster had me swooning, especially as I got to understand him more.

Ahh this book was so much fun and I need the second one immediately!! First off thank you to the author for my gifted ARC copy in exchange for an honest review.

I seriously had no idea what to expect going into this one. This is a winter romantasy that takes place over the 12 days of Yule. There are Phoenixes bonded to riders, morally grey characters, political intrigue and rebellion, folklore and magic, second chance romance with lots of yearning and history.

Typically my favorite part of a romantasy is the romance buttt in this one the plot is actually what had me so addicted. It was fast paced and I was never sure where it was going. The ending was perfection and that epilogue from a certain characters POV 👀 I need more of him!!! There were definitely times where the world building and magic system confused me a lot and I found myself getting stuck, not sure if this was me and my brain or the writing. But honestly the story was so intriguing that didn’t matter I still didn’t want to put the book down!!

Definitely recommend putting this on your winter TBR you want a unique romantasy read!!

Thank you to the author and JBTP for the complementary advanced reader copy. All thoughts and opinions are my own.

I was so excited for this one! The magical elements were unique, the phoenixes were so cool, and the curse had me captivated, but unfortunately I just couldn't fully connect as the story progressed.

At times, the pacing felt kind of all over the place. Rapid and overwhelming to start, then slow and trudging in others. I kept having to pull my attention back to the book, which almost never happens to me, and made it hard for me to connect to the romance between the leads. There also was a lot of repetition, and as someone who has a brain that latches onto patterns, seeing the same phrase, movement, or punctuation (in this case, excessive use of ellipses to create pause) over and over again started to wear on me.

I truly think a lot of people will fall in love with this one, but for me, it was just a middle-of-the-road book. Either way, people who enjoy a slow burn fantasy that's light on romance should love this one.

When The Sky Burns is the first book in the Skyworld series, and it is such an original romantasy in my eyes, as I’ve never a) read anything with phoenix being the main mystical creature and b) set around Yule!

It took me a few chapters to get my head around the different worlds and characters etc, but once I did, I was immersed in the world. I loved the wintery feel to the setting.

The ending blew my mind and has got me waiting for the next book already! I loved following Aliwen’s relationship and history with Aster, although my only criticism would be I would’ve loved a few more 🌶️ scenes 🤣

I’d definitely recommend this book to romantasy lovers, especially those who love phoenixes, strong female main characters and magical (and somewhat sentient) books🧡

Thank you to @randomthingstours @islalockwoodauthor for my copy and the amazing PR package!! 💙

Romantasy is full of books about dragons, shifters, and werewolves, so 'When The Sky Burns' is a refreshing change of pace. This story had the premise of riders but with phoenixes.
I also enjoyed the sentient books. Our FMC starts off working in library repairing books. Somehow, the books respond to her. I love this idea!
However, in the beginning, the world building fumbles a little bit as there's a lot of information but little background. There's 3 worlds, the story of Yule, magic, phoenixes, etc. It's around the 40- 50% mark that things start making sense.
Thank you for choosing me to be an ARC reader.

I am sat for this series! Hidden identities, badass women, phoenix riders, curses, Celtic Yule based lore, second chance romance - it has it all and is beautifully written. If you are a fan of Fourth Wing, The Crowns of Nyaxia series by Carissa Broadbent or The Wolf King by Lauren Palphreyman this is for you.

Aliwen is a great FMC. A slave, rebel and spy, she is determined to get her revenge and take back her kingdom from the kings and Phoenix riders that betrayed her family. She's pushing down a lot of pain and trauma to become the force her people need to regain their freedom. On top of that, she discovers she is the only person who can break the curse on the Phoenixes and their riders and restore the balance of magic and power in the kingdoms. Captured by the riders who betrayed her brother and the man she thought was dead, she has 12 nights to break the curse and save her family.

You are dropped right into the action on page one and the pace doesn't let up. The writing is beautiful and the lore and world building were so interesting. This is not the festive Yule we know, but a dark, dangerous time where the cursed magic of the phoenixes makes them and people unstable and dangerous.

There is a lot of political intrigue and everyone is hiding something. Wren and her cousins, Thorn and Ember, are all working as rebels to take back their kingdom, but they all have plans and secrets they are keeping from each other. Then the Phoenix riders are broken into different factions and plotting against each other. No one knows who to trust and it is going to make for a great series.

This is a plot driven book and the romance is secondary. I'm also wondering if there may be a love triangle brewing for book 2. I think we may have Wolf King situation where one of our secondary characters takes a bigger role. And if so I'm here for it!

This is a planned 6 book series made of of 3 duets. Absolutely put this on your TBR.

This book was such an amazing read! I really enjoyed how she worked in the nights of yore with everything else she packed into this amazing story. This book is action packed and will have you hooked from the beginning! This book does have some spice but it was very tastefully done and does not take away from the main story. I can't wait to see where she takes our FMC next!

Just started reading, 35 pages in, and it feels like we’re starting in the middle of a story. Also, we have been in this one persons head this whole time and I don’t know her name or what she looks like. I hope this is not one of these self insert books. I expect the author to build out characters and tell us what they look and sound like and if I want the character to be brunette because I am brunette then that’s just how I’ll picture her.. but I still want the author to build out the character description. Also the character just said “ as Thorn always said…” who the hell is Thorn. We have had no mention of this person and the character quotes them and gives no explanation or background. This book needs edits. I can’t keep going.

From the very beginning, this book was packed with action and adventure. It was fast paced and very easy to understand what was happening. I feel like with some romantasy’s it’s easy to loose yourself with the geographical aspect of things but this was straight forward and I didn’t need to look back at the map.
In my opinion the world and lore building was rich and detailed, combine this with this addicting plot then you have an easy 5 star read.

This book has abit of everything I love to read in a romantasy. It has hidden identities, political intrigue, curses, lore, interesting magic systems and tension. The complete package!

We have all heard of dragons in this genre but let me tell you Phoenixes have just entered the chat! I thought this was very unique. It was also so interesting to see how Isla weaved together the magic system with the twelve nights of Yule.

Our FMC Aliwen, is strong, fiesty and has had her life turned upside down by the fall of her kingdom. Hidden away she has been bidding her time and is fighting to save her brother and reclaim her kingdom alongside her cousins from the kings and phoenix riders that betrayed her family. She is now a rebel with a talent of restoring magic to broken books. One day she decides to steal a very important book for someone to ensure safe passage for her and her cousins out of the city except not all goes to exactly how she has planned. She finds herself in danger as the phoenixes and their riders close in.

As Yule approaches she discover that she is the only one able to break the curse on the phoenixes and their riders but she only has 12 nights to do it.

The further the story progresses the phoenixes and their riders become more unstable and dangerous creating a suspenseful count down. She finds herself questioning people she once trusted as secrets are revealed - everything she once knew weren’t always as they seemed.

Now let’s talk about the characters and the romance…

There is some spice in it for those who look for spice in your books but the scenes do not overshadow the plot and whilst they are very hot it is minimal but I found this very refreshing. I prefer the first book to get a strong plot and then watch a relationship blossom from there. Second chance tropes aren’t usually my favourite but I think Isla here has completely changed that for me. I really enjoyed reading Aliwen reconnecting with Aster. Three years apart and feelings that never went away - there feelings for each other still very obvious. It took me ages to figure Aster’s character out but once I did he had me swooning.
Although I must say even though Torrin was the villain in this - something had me always pulling in his direction. I do hope to see more of him in the next book.

If you’re looking for a mid-winter Romantasy then this book is for you and is out everywhere now!

Review of Advanced Copy Recieved by Author thank you for the opportunity
Ok so much going on this was a dark, fiery midwinter escape. If you’re looking for a dark, atmospheric romantasy to curl up with during the cold winter months, Isla Lockwood’s debut, When the Sky Burns, is exactly the kind of high stakes, magic filled journey you need. This isn't your typical happily ever after fairy tale. It’s a dark, midwinter fantasy set in a world where the veil between three realms the Skyworld, the Earthworld, and the Otherworld thins during the Twelve Nights of Yule. The atmosphere is thick with tension, ancient magic, and the constant threat of "Yule Madness." It’s chilly, it’s dangerous, and it’s filled with cursed phoenix riders who are as volatile as they are deadly. We have out FMC Aliwen who goes by the alias "Feather", a former Annatalian royal living in hiding as a library apprentice in the grim, crumbling Craven City. She’s not just dusting books she’s a spy for the rebellion. Her life is a balancing act of survival, secret missions, and trying to protect her younger cousins, Ember and Thorn, from the men who conquered their land.
The story kicks off with a bang when Aliwen’s plan to steal a codex goes sideways, forcing her into a dangerous game of cat and mouse with the very people she’s trying to overthrow. And when Isla warned that everyone is morally grey....well you’ll find yourself questioning who to trust, especially when it comes to the enigmatic Aster, Aliwen’s childhood friend and rebel leader, and the complex dangerous Riders she encounters.The concept of the "Skyworld" and the bond between Riders and their phoenixes is fascinating and new. I also loves the idea that the library itself is alive rumbling in warning or thanks was really a cool, unique touch. Between the forbidden romance, the political intrigue, and the constant threat of being discovered, the pacing is relentless. Aliwen is a fantastic protagonist she’s a survivor, a spy, and a killer who has been forged by trauma but refuses to break.There are plenty of intense, brooding, and dangerous phoenix riders to keep the romantic tension simmering too. When the Sky Burns is a gripping start to the Skyworld series. It’s dark, it’s spicy, and it’s packed with impossible choices. Just be prepared the author also warns that this book ends on a cliffhanger, and based on the intensity of the story, you’re going to be desperate for book two. If you love stories about rebellion, ancient curses, and heroines who are as sharp as the daggers they carry, this is a must read. Just make sure you keep your fires stoked you wouldn't want to go and get "Lost" while reading it!

When the Sky Burns is one of the most engaging, exciting, fast-paced but well-rounded and UNIQUE romantasies I've read this year!

It starts off SO quick and just does not slow down. The entire book is fast-paced and adventurous - no waiting for something cool or exciting to happen here. Magic (and danger) are in the air from page 1, and Aliwen (Wren, Feather, etc. IYKYK) was such a likeable character. She's tough, determined, quick witted and honestly kinda real for her impulses and quickness to anger - I guess I resonated with that a bit LOL. She is fighting for her kingdom, her family, and her life and if it was me in her situation I probably would have crushed under the pressure of it all so pop off girl.

The world-building and character development in this book was phenomenal. There are so many unique aspects to the world, the curse, the creatures and the varying regions and landscapes. The author beautifully describes the scenery, details like the crunching snow beneath hooves while the world is silent and dangers hunt from above had me IN THIS, and descriptions of differences between how Wren THOUGHT places were meant to appear and what they really looked like helped bring everything full circle. The Yule setting, dark winter, evil curse, witches, phoenix riders, old magic and anthropomorphic books gave this story such a moody, gothic fantasy and enchanting vibe!

I truly loved Wren from the start, she felt like such a relatable character through her hardships, the fiery re-ignition of romance, and her questions and hesitations through her journey from the countless betrayals she'd faced through the years. Aster on the other hand took me a bit to appreciate & understand, but for good reason. He is so perfectly mysterious and hard to read, weathered from war and rebellion and just trying to survive. The romance between them was perfect. It doesn't take over the plot, but there's yearning and a push/pull that just kept me guessing and wanting peace for them both. The spice was minimal but well placed/timed, and I really enjoyed their overall banter and rediscovery of one another.

This was an absolute 5 star read, and I literally cannot wait for book 2 because THAT ENDING OMG!! Gahhh I NEED IT. It's going to be hard to move on from this, but I will be eagerly & impatiently awaiting the next installment hehe. I had the absolute pleasure of getting to read an ARC before this was released to the world, thank you to the author & Jess Beyond the Pages for providing a complimentary copy for review and having me on the team, I can't wait for what is to come!

What better way to get into the spirit of Christmas is there, than tucking yourself up with a Yule season themed fantasy book?

A Yule season themed fantasy book with Phoenixs and bonded riders of course 🤗

This is honestly the perfect Yule gift for the book lover in your life.

'The world no longer waits. On the fourth night, what has awakened takes form. Hiding ends as the fates unfold their true course. There is no more darkness to hide in. What was concealed in shadow, steps forward. Where doubt once lived, courage breaks forth.
This is the night of recognition. Not of what you wish to be, but of what you have always been waiting to become. Beware the night you are seen—for you do not become someone new—you are named for who you already are.'

Inspired from Northern European, mainly Insular Celtic and Germainic traditions. When the sky burns blends myth, folklore and seasonal beliefs and rituals into a wonderful, easy to follow world full of magic and magical creatures. It follows Aliwen, a princess of the overthrown Annatalian lands, who is an under cover rebel searching for a book to help break the curse that has taken over the Skyworld creatures and their riders. Every year when the veil is at its thinnest, the Skyworld magic leaks over the lands where Yulemots set about an uncontrollable craze to Phoenixs and their riders. Each year is getting worse and the only way to end the brutality caused during the 12 nights of Yule is to end the curse the witches cast many years ago.

Or is it? 🫢

While in search of books that are said to have been destroyed, Aliwen finds a sentient grimoire hell bent on guiding her to her true fate. She soon learns that fighting against her own path to save her cousins could ruin everything and that Ember and Thorne have their own fates to pursue. When she finally embraces her calling, she discovers untold truths that change everything she thought she knew.

A well paced adventure from the very beginning. While I had predicted the ending pretty easily, the book has me invested already, and i am waiting in great anticipation for the next installment to this series. 🥰 I was sent a physical copy to ARC read, but I loved it so much, there is now a stunning special edition sat proudly next it. I can't wait to see what happens next.

***Thank you to Isla Lockwood for the ARC, i am so very greatful to have been selected for one of your beautiful PR packages.
The above review is my honest opinion and has not been influenced in any way.

"I need you to know in another life it would've always been you. It is always for you."

UGH! MY HEART!!!

As a romance-focused fantasy girlie, I can confidently say that When the Sky Burns was AMAZING! This book gave me everything I love about romantasy: a fast-paced storyline, intriguing characters, undeniable chemistry, and a slow-burn romance that had me completely invested. I honestly didn't want to put it down!

One of the things I appreciated most was the pacing. While the romance was a slow burn, the actual story was anything but slow. There was always something happening that kept me turning the pages, and I loved how the relationships developed alongside all the action and uncertainty.

And then there's ASTER! Oh, Aster. I absolutely loved the many layers of his character. Was he the good guy? The bad guy? Somewhere in between? I spent so much time questioning his true loyalties and trying to figure out where he stood. What made him even more intriguing was how strongly his presence was felt, even when we weren't hearing things directly from his perspective. His voice was definitely heard, and I was hanging on to every little clue!

But let's talk about Aliwen because WHAT A FEMALE CHARACTER! You know I love a strong FMC, and Aliwen certainly delivered. I loved her strength, her determination, and the way she navigated everything thrown at her. However, some of her decisions had me gripping my blanket and holding on for dear life! There were moments when I wanted to cheer her on and others when I wanted to scream, "GIRL, WHAT ARE YOU DOING?!" And honestly, I loved every second of that emotional rollercoaster.

The combination of the fast-paced fantasy world and the slow-building romantic tension was absolutely perfect for me. I was constantly questioning motives, falling harder for the characters, and wondering what could possibly happen next. This book gave me all the emotions I want from a great romantasy, and that opening quote? CHEF'S KISS!

If you love fantasy with romance at its heart, complicated characters, questionable loyalties, a strong female lead, and enough twists to keep you guessing, then When the Sky Burns absolutely deserves a spot on your reading list!

A special thank you to the author for allowing me to be an ARC reader. I am already itching to dive into the next book because this was ONE ROLLERCOASTER RIDE I AM NOT READY TO GET OFF!!!
