NIKOLAI PETROV HATES LIES.

Finding out he’s supposed to be the next Vampire King of Raspien was not something Nikolai Petrov ever expected. Torn from his family and his home, Nikolai is thrust into an unfamiliar world with unfamiliar people.

But it does not feel like the court of vipers he was warned about. Nikolai is surprised by the warmth of his new family and Lord Councilman Caius Varga, immersed in his new school and his new friends, and somewhere along the line, he stops counting down the days until his return home.

His willingness to stay and take up his promised role only grows when he meets the enchanting Lord in Waiting of Amenti, Viktor Kamel. Swept up in romance, friendship and the prospect of learning under the Petrov Academy’s best healers, Nikolai finds himself more deeply entangled than ever in his role as a prince of Raspien.

But things aren’t always what they seem. Nikolai’s warmth, kindness and honesty cannot protect him from lies told in decades past; in the end, the truth always comes knocking and the shadows of the past have teeth as deadly as the ugliest of secrets.

Impostor is the second book of the Children of Lorcan series, following Nikolai Petrov as he first navigates Raspien and his life as crown prince.

Impostor has an entirely different vibe than Usurper, stemming from a different POV and main character. Where Dmitry was fully focused on himself, keeping a distance to people, Nikolai's the opposite. With every interaction, you start caring about the people Nik cares about, cry and love with him - he opens his heart fully both to the people around him, and to us as the readers.
We also get to see a lot of character we already met in Usurper, like Yevgeni, Caius, or young Yuri, as well as children of people we met. Seeing them in a whole different light and through Nik's warmth gives us a different perspective of how unreliable Dmitry as a narrator truly is.

With the reader knowing more about Nikolai than he does himself, there's always the tension of when the big reveal is going to happen. Through all the soft and sweet moments with his new-found friends, partner, and mentors, there's always the little nagging voice. Still, there are a lot of very sweet moments throughout the whole book.

My favorite relationship wasn't even between Nik and Viktor, but the mentor-mentee trust between Nik and Caius. We get to know Caius in a whole different way, and he shot up to become my favorite character in the whole series.

Of course it wouldn't be a Jess Rose book without heartbreak, and yes, that definitely happens. I was mad for days, one specific scene haunting me - which shows how perfectly well it was written.

Overall, we see different sides of characters we already thought to know: both positively and negatively. Impostor clearly shows why Usurper was written the way it was, and I'm scared of what's to come, but also excited to read the next installation.

I received this book as an Advance Reader Copy but I'm freely leaving this review. All opinions are my own.

I got this as an ARC from my friend, and I’m so fucking proud, cause this book is AMAZING.
I read it in under a day and a half, and for the last at least 1.5 hours of that, I was crying the whole time. I was all sad and mad and happy, and all the things.
All the feelings.

Nikolai, the MMC, is such a little ray of sunshine.
I just love him. And his beautiful boyfriend.
If they were older I would wonder if maybe you can have two book-boyfriends when they’re boyfriends in said book. I think yes.
And I now officially hate his dad!
«[…]guilty of indecent behavior.”, my ass!


I loved this book.
This book is so full of friendship, and love, and hate and forgiveness and joy.
No spice and all the tension.
You should read it.
I think you will love it too.

I finished Impostor last night and decided to give myself one night of sleep before sitting down to write this review. Was that one night enough to work through my feelings and inner turmoil? Nowhere near enough, but I owe it to Impostor to try.

If there were one word to describe both Impostor and its predecessor, Usurper, it would be emotions. Emotions of the deepest, rawest kind. Emotions that turn your heart into a puddle on the floor with their sheer intensity and depth.

I struggle to find the right words for this experience. Not reading, experience. Otherworldly and encompassing. Immersive and enthralling. Hurtful to the bone. Painstakingly beautiful.

What makes this experience so special are the characters. They are so vivid, multi-layered, and real. They each carry their own burdens.

Nikolai, finding himself a prince in a country he knows almost nothing about, surrounded by politics and power plays. His pure heart is what grounds him in these new circumstances. His pure heart and his pure soul. Just thinking about him brings tears to my eyes, because he is the light and the sun.

Caius, showing us a different side of himself, one we didn't have the chance to witness in Usurper. My heart ached for him on so many occasions, and his circumstances gutted me each time I thought of him. He has gone from a slightly unlikable character in Usurper to one I would defend until my last breath.

Viktor, another ray of sunshine. He made my heart sing, and his love and devotion are something we should all strive to achieve. There are no right words to express just how much I adore him, and how grateful I am for his presence not just in Nikolai's, but in our lives as well.

Impostor is a tale. A tale of accepting who you are and what truly matters. A tale of a family forged not by blood but by choice and love. A tale of family ties, of pain, of betrayal. A tale of finding sanctuary in people. A tale of self-doubt, self-worth, and inner struggles. Above all, it is a tale of love. Love between partners, friends, and family. Love that can be all-encompassing, love that can heal, and love that can hurt. A tale for a lifetime.

So, gift yourself the story of Nikolai, Viktor, Caius, and others. Meet new characters and see old ones in a new light. Live, love, and hurt with them. But above all, just live.

Thank you, Jess, once again, for having me on your team. It's an honor I don't take for granted.

Exceptionally good. The second book in this series focuses on the second generation. We see the power of love, friendship, forgiveness but also the ugliness of hatred, hardship and revenge. The descriptions are on point highlighting the clear differences that exist between locations in the Lorcan universe. Can't wait for book 3.

The second book in a wider series and I ate it up!

True, because life is hectic, it took me about 2 weeks to read this ARC. But this has nothing to do with the book itself, the story or the writing.

I really enjoyed reading Usurper and was very curious as to what would happen next. And I wasn’t expecting this! A huge time jump, and a complete 180 in MC character wise…

If you enjoy character driven storytelling and are able to go with the flow, this is book you should definitely pick up. Impostor tells a comforting story with huge cinnamon roll vibes and wholesome feels. But since it’s Jess… don’t get too comfortable.

When reading the first half of the book I remember being so proud of how much the writing has improved. It really feels like the author has grown and grown more confident in their writing. Well done!

There is bound to be a character for you in this story and I certainly fell in love with a couple of them.

Beware that when you’re a more plot motivated reader, this series isn’t. So be careful when reading; as mentioned before this series isn’t heavily character-driven, more based on the atmosphere characters bring and the dialogue and their interactions. The story is not just entertaining but socially relevant and engaging.

Vampires might still not be my thing, but after having read Usurper and getting to know the world of Lorcan, this has been a lot easier for me to enjoy and be swept up in the emotions. The times my hand flew to my mouth.. 🙈 I can’t even…

Congratulations on another great story. I wonder what part 3 will be about because I’m clueless!

📕Oh, these characters have my heart
📗character driven/ differing views on events from first book in series
📘all the emotions at the highest intensity
📙Secrets, reveals, twists, turns. Very well-written

Imposter by J.M Rose is the second book in their Children of Lorcan series. The series debuted in March of this  year and continues with the release of this spellbinding followup. This series is an epic chronicle of the conflict between dynasties, the love and loss of generations, and the bonds of both blood and found family.

In this book J.M. Rose switched the narrator to the younger generation of the characters who ran the show in book one. Dmitry Petrov’s son, Niklolai has been called back to the kingdom responsible for the pain and trauma in his father’s life. The thing is, his father has sent him back with limited  knowledge and he may not know everything he needs to know to survive. Nikolai has returned to be the heir to the throne, the heir to King Yevgeni who was responsible for so much of Dmitry’s pain. 

The change in narrator for this series is a very clever and creative way to reveal different perspectives on things that have happened in the previous book in the series.  This feels authentic because there are so many times in life when our interpretation of an event can be completely different than someone else’s.

The focus of this book is Nikolai’s reintegration to Raspien and his royal lineage. Nikolai joins the vampire academy…years behind his peers… and undertakes training in everything from diplomacy to his true calling - healing. As he struggles with being clumsy, feeling as though he doesn’t belong and missing his family - he begins to gather friends and mentors. 

Who is Nikolai really? Which of his qualities and instincts come from his blood and which comes from his found family? There are many questions facing Nikolai as he begins to carve out a place for himself in Raspien. Nikolai is dealing with the fallout from his father’s youth, and from past transgressions of which he has no knowledge. He’s in danger from many sides… and despite the fact that I felt I knew what might happen, the author surprised me yet again.

The characters in this series are all memorable. Every time I read a new one, I’m convinced they will be my favourite. This series is rich with realistic characters. Every single soul who is introduced comes with a backstory, meaning, influence on the unfolding plot. In particular, I loved the supporting cast of friends in this tale. Each of the people that become Nikolai’s friend bring with them a vehicle for revealing more about the story, more about the Prince and more about the threats he faces. Every character matters.

“If he wanted to stab you, I would follow him so I could cover up his tracks. Because I’ll have you know there is nobody living or dead who will protect him the way I will.” - Ilya

J.M. Rose has great skill when it comes to writing characters who generate emotional connections. The author introduces their characters gently, letting them tell their own stories and reveal their own weaknesses and flaws. I never double that Rose has these characters in hand, but they are always allowed to breathe and grow. It’s impossible for me to pick up a book by this author and remain disconnected.  I often find with such a sweeping sage that the sheer number of characters can be overwhelming. I never find this with the books of J.M. Rose. 

Jess has a way of crafting characters that burrow their ways into my soul. The ones I loathe, I will come to love and the ones I love will be taken down in a sneaky unveiling. I'm always apprehensive and terrified and enamoured at the same time. Oh Jess - you are and will always be one of my favourite authors.

The plot of this book is complex enough to be fascinating and still remarkably easy to follow considering the vast sandbox of the world that Rose is creating. The pacing is pitch perfect allowing the reader to follow along on the character’s journeys. This creates such a wonderful connection for me to the people I’m reading about. I come away from these books feeling as though the characters are people that I know - not a creation on a page.

There are numerous themes in this series even though there are more books to come. Found family plays a huge role in the Children of Lorcan Series. Most of the characters whether they are main or supporting face challenges with their familial relationships. Friends are often the people that are the most reliable, the ones who show up when the rest of the world has stepped away.

"He watched him from the crack in the open doorway, a silent onlooker; the viewer of a work of art, destined to perceive, always to see, never to be seen."

This book has changed the way that I think about writing. I always close the cover on books by J.M. Rose and find myself lingering in the emotion. These books are beautiful and it’s a gift to read them. I cried several times while reading Nikolai’s story and I don’t regret a single tear. What a joy it is to reach a book that I can connect with so deeply.

I was given an eARC of this book in exchange for an honest review. I have already pre-ordered a copy!

I was given a copy of 'Imposter' ahead of time as an ARC reader (thank you!), however my opinions are honest.

I will preface this review by mentioning that I started 'Imposter' on a Wednesday, accidentally read half of the book in one sitting and then had to actively put it away until the weekend. Y'know, just in case it went the 'Usurper' route, I couldn't afford another 3am weekday mental break.

'Imposter' is a character-driven book which lures you in with its vivid descriptions of our MC's inner world, and slowly lulls you into a cocoon of hope as you live through all of sweet Nik's first experiences as he is thrown to the wolves in the cut-throat world of Raspien, which seems to have welcomed him with open arms, if not an open heart.

He is faced with a myriad of responsibilities which he must quickly learn to bear, all of which he was woefully unprepared to shoulder at all. Throughout this harsh reality he strives to put his best foot forward with every step - even if the ground is more slippery than he expected. He forms genuine friendships, and finds joy in the privilege of his new education, a passion he'd otherwise not been able to know, and balances out various difficult truths with hope that he if he must be King then he can create a better future for Raspien. One where nobody has to live in fear of who they are, or of what they must become.

He is quick to be kind and honest above all else, except his heart's desire is a very dangerous threat to his reign, and his life. We get to watch him grow to know himself, as his confidence and sense of self blossoms enough for Nik to be able to choose what risks he is willing to take. (And gods almighty it is truly the sweetest pay-off to witness, I hold so much love in my heart for these boys.)

Of course eventually my heart was indeed ripped right out of my chest and force-fed back down my throat (J.M. Rose is simply one of those authors, and I will keep coming back for seconds).
We are faced with old lies and deep scars, irreparable familial ties, and for me personally a great deal of empathetical torment as I slowly grew to hate a character I once very much loved. Nothing is what it seems, and there appears to be enough damage that can be done to a heart to completely carve out all that was once good.

Despite being far better prepared for the near-certain doom that I was sure to face, once I finished reading I still had to take a week to let the rage die down enough for my brain to form thoughts into coherent sentences, hence this tardy review. Props to the author for knowing just how to shatter me.

On a less serious note, this group of friends is one of the most fun and interesting dynamics I've come across. They each have distinct and intense personalities, and I would hug 'em to death if I could. Rose excels at creating characters that feel so real you could DM them on Insta. I spent this past week with them living in my head, talking to myself and wondering about their lives. I shall be holding room for them for as long as the author keeps writing.

4.5 Stars

(half a star off for the trope of confusion due to miscommunication or misunderstanding in moments I felt it unnecessary. Mercifully not a major plot driver/diversion at all, but a personal pet peeve nonetheless).

IMPOSTER has been an awaited read for me ever since JM Rose told me about Nikolai and Viktor well over a year ago. I enjoyed USURPER greatly, the first book in the Children of Lorcan series, but this second book wiped the floor with USURPER.

My reviews are ever honest, despite my relationship with the author, so I will admit that the first quarter of the book was a little slow to build, but by no means boring or filler-ish. We were introduced to important characters, Nikolai's life in the palace and at the Academy, and his relationships are explored in ways that both set up the rest of the book but also prepare for the rest of the series. IMPOSTER, like USURPER, is a more medium paced book, but definitely a quicker read then the first book, and picked up in pace and plot after the romance central to the story was established. I DEVOURED this book, especially the second half.

Nikolai and Viktor's romance is as beautiful as the prose, and their initial skirting around each other had me screaming and yearning to bang their heads together. Their forages into a relationship and the trials that come with it and the greater context of their lives as noble vampires was explored in such a complex, meaningful, heart wrenching way. Their journey to their happy ending was worked for, and so deserved.

As always, Rose pays close attention to characters, their characters always complex and realistic, full of life and jumping off the page. One of the things I enjoy so much about Rose's writing is how much care they put into the side characters, ensuring they stand on their own, giving us glimpses into their lives, and showing how the narrative and politics not only shapes the main character, but also those around him.

And dear God, this new perspective on Yevgeni and Caius was impeccable, important, and so heartbreaking. Nikolai's narration really showed how biased and skewed Dmitry's was in USURPER, giving us a better incite into the relationship between Dmitry and Yevgeni. The political ending BROKE me just as much as the romantic ending for Nikolai and Viktor was beyond satisfying and so heartwarming. I was kicking my feet and screaming in between crying over Caius. JM Rose, you deserve to be forced to wear socks nonstop for that.

JM Rose has secured themselves not only as a favourite author of mine separate from their firm place in my heart, but also as an auto-buy author for me. I will read anything and everything they write. Please give me the next book and the entire rest of the series right now.

When I tell you noone breaks your heart as beautifully and tear-worthy as J.M. Rose, would you believe me?

What began with Usurper continues in Impostor.
Wonderful characters you adore, love and root for. The best Mentors and father figures who you wish to adopt. And the best kind of friendship, the deepest love and a tragedy so hurtful you can only find in the best friends, charming love interests and family.

Iconic Albert will always be my adopted father but in Impostor I met Darius, who I already predicted to be a new favorite mentor of mine, and a surprise:
Viktor's father, Lord Ramun, stole my heart with his gentle and wise presence.

I also was so heartbroken for Caius 😔
I was not ready for him in Usurper but now in Impostor... Caius, you need to be protected at all costs! You are a gem and you deserve so much better.
But the heart wants what it wants.

Finally, Nikolai. What a sunshine you are! And you turned out to be so much stronger than anyone initially thought. You went through hell, you got your Black Cat and you two forged such a strong beautiful bond.
At last, Yevgeni. You have turned into such a cruel bastard. And yet... you are tragic.

My favorite small moment?
The cameo of my chosen father figure in one of the later chapters. He isn't mentioned by name but noone would miss that it's Albert 🤭❤️

Needless to say, I loved Impostor! I need more!
But J.M. Rose promised there is more and spin-offs 🔥
The Children Of Lorcan is an epic dark fantasy which definitely found a place in my top favorite book series.

It is with absolute heartache 💔 that I'm writing ✍️ this review..... @Jess - Throughout the reading of Impostor, we have been in touch, and just a couple of hours ago, I told you that I will always love you 😍 but that I also hate you 😉 ..... I do not say this lightly, but obviously jokingly 😅..... OK, I'll stop now.

Here's my review points (I promise to leave spoilers):

1. The character build-ups are always exceptionally flawless 💖 and the geographical descriptions of the places in Denya's world 🌎 are to die for.

2. The love-hate-revenge dynamics are astounding, and the cycle breaking is honestly to die for between generations 😳

3. I don't especially like some of the chapters at the end of the book 📔 but I do understand the reason behind them.

For those ARC readers currently reading 😋, I would not recommend you skip to the end to see what happens. 🙏 Please read the book 📖 savouring it until the end at a slow pace, as Book 3 is a bit far away 😢 for us to enjoy just yet!!! 😉

Imposter tells the story of Nickolai Petrov, son of Dmitry from book 1, as he is thrust into the world of vampires and politics by being sent to the kingdom his father grew up in to be named as crown prince under Dina’s younger brother who has been king for many years now. He discovers friendships, love, harsh truths, pain, and much more on his journey.

J.M. Rose has done it again. I had very high expectations coming into Imposter from how much Usurper was genuinely brain altering to read and how much I absolutely adored the story. This was not even a little bit disappointing. It lived up to the expectations and exceeded them. I love the characters in this and their unique flaws and personalities, I adore Nick’s characterization, and I love being able to dive back into the world that sucked me into Usurper. What a read!

Where do I even start!? Okay first if you don’t like series don’t read this as this is book two. That being said this book had me all over the place with my feels😭. It was all worth it in the end 😉 I had mixed feelings about a certain character and fell in love with him as it all unfolded. I would honestly recommend you read Usurper book one. It all ties together. This is a multi-generational series and I can’t wait to read the next book!


I received this book as an ARC but my opinions are my own. As always I invite you to form your own!

*it is advised you read Usurper first as it has important back story that is relevant here.


I really don't know where to start.

There is SOOO much to talk about, and so many things I absolutely LOVED. My emotions got taken out on a roller-coaster that never ended.

Nikolai is an absolute sweetheart, he is sunshine personified (abiet a clumsy sunshine). But he is inheritantly good, so frustratingly good where others would choose revenge he does not.

Viktor is a bit broody, the strong silent type. But he is GONE for Nikolai they are literal soul mates. I love all the love Viktor has for Nikolai and vise versa.

The characters we meet in Imposter are so well written. Nikolai's group of friends are hillarious, the friend banter between them is laugh out loud hillarious (Oleg I'm looking at you).

The way in which Imposter explores so many different relationships is incredible. We get to see more of Caius and Yevengi and their interesting dynamic.

We meet returning characters from Usurper and see some in a whole new light.

This deserves more than 5 stars and honestly I just loved it.

I love that this series is a slower pace, and that they're chunky. You settle in, knowing full well you are going to explore these characters in depth, that you're going to get to know them and love them in spite of their flaws and be emotionally traumatised in the process!

I adored Nik. I love that his heart is so open to making the world a better place, that he understands that to do it, cycles have to be broken - no matter the personal cost. Those traits could be easily considered a weakness, but Rose very cleverly highlights the honourable and potent power in making those hard choices to be kind when doing the right thing.

My heart was in my throat for so many moments, and it was, as expected with a book written by Rose... an emotional journey. So so many feelings. I genuinely was so sad that it ended. I cannot wait to see what happens in book 3.
