Aside from one authorial quirk I don't remember from the other books (constantly referring to Petra's companion as "the friends" -- just felt awkward), I thought this was an exciting, dramatic, and even moving conclusion to the Kronos Chronicles. Sometimes it felt a little too fast-paced, being crammed as it was with several storylines which didn't always get as much development as they should, but the payoff to all those stories coming together was still wonderful. Petra and Astrophil especially were in top form.
*Longer review later -- you guys know I'll get to it eventually. I'm really behind at all of life right now.*
The Jewel of Kalderash is the end of the trilogy and can't be described without spoiling everything. In short, it's a magnificent, heartrending end to the trilogy. The world building is amazing. Astophil is a very smart and witty spider! Neel is a sneaky thief with interesting humour and Tomik is magic with his talent for glass bombs. The author tweaked the history a little but surprisingly revolved it around many interesting and real events/objects. The Mercator globes are real. English politics explained is real. That magical clock in Prague is also real. Also I didn't know coconut hair (coir) is very important in making rope! This was such a wonderful read!
If you're into fantasy genre, you'd love meeting the tin spider Astrophil. If you're into adventures, you'd love following Petra around the world in order to save her father. If you're into pirates and ships, you'd love the Maraki and Neel's crew looking after the Celestial globes. If you're into sword fights and murder mysteries you would love John Dee and the story surrounding him. If you love interesting inventions you would love Master Kronos and Tomik Stakan. If you love kingdoms, politics and things falling apart in order to come together you would enjoy this trilogy :)
P.S if you're looking for Nikolai, you'd find some of him in Neel
I loved this last book in the trilogy so much! The plot really surprised me, and I loved the new characters and old. In this book, Petra is still on a quest to save her father from the evil Prince of Bohemia, and naturally Tomik and Neel are along for the ride. My favorite character is still Astrophil, the tin spider with a big brain and an even bigger heart. Once again, John Dee makes an appearance, and of course intrigue and spying and political machinations follow in his wake.
The stakes are definitely higher in this book, with assassinations going on all over the place and various thrones of various countries up for grabs. Petra has some tough choices to make, not only in her personal friendships, but also in deciding how much she is really willing to sacrifice to achieve peace for her country and the people she loves.
I loved that the romance is very minimal in all these books, but it IS there and adds a little spice to the story. All the characters are so diverse and interesting, each with a different personality and voice. They are all dashing and brave and wild! I got really attached to some of them, and then the emotions started coming out, and I was gasping and clutching the book every time MY characters were in danger or doing something stupid. I love a book that pulls you in like that!
I had no idea where some of these plot twists were going, and I was completely surprised by all the wild places Petra ends up in. I love this entire series! Wonderful adventures with sweet characters and snappy dialogue!
I loved this book. I loved the series. I love the characters. I love the action and the magic! I'm begging Marie Rutkoski to eventually write more. I recommend this series; this author; to any one of any age that loves adventure, magic, budding love, good vs evil.... etc... Such enjoyable reads!
Though there are certainly people who would argue otherwise, I have always considered the Kronos Chronicles to be a MG or middle-grade series. (MG being on one end of the Young Adult spectrum.) Not that the series was lacking in sophistication nor depth of character, but because the books were outstanding, and yet still appropriate for younger readers.
In fact, in my opinion Marie Rutkoski is one of THE best MG authors. She can tell a whomping good story; make it engaging for teens as well as adults, and that is indeed a rare talent. And so I gave "The Cabinet of Wonders" 5-Stars. And "The Celestial Globe" 4-Stars.
But something happened with "Jewel of Kalderash". I didn't have a problem with the ending being a bit rushed, but I did have a problem with the fact that I never re-connected with Petra. Her plight and concern about her father wasn't interesting any more, and instead all my attention was on Neel and his predicament. And I found myself wishing there were more chapters about him, and the Roma on the island.
Still, the word-smithing was still excellent, and this Jewel is worth reading so that you can see all the loose ends brought together, but I am definitely glad the series is at an end.
Highly recommend this series. It's brilliantly done and the fact that younger readers won't have to wait for the next volume in the series to come out may sustain the excitement better than a year long hiatus.
Although I found this this trilogy to be better than most modern books of its kind, I was disappointed by how it all ended. Things wrapped up too quickly, and it felt very rushed. If you skipped a page or two toward the end, you would miss virtually everything. There was little sense of the magnitude of the grand battle that is the culmination of the story.
There is an underlying confusion that is unsettling. The primary setting is Europe (Bohemia - now part of the Czech Republic) in the middle years of the 16th century (when Ferdinand I was Habsburg Emperor and Elizabeth I was queen of England). However, despite setting the book in this specific period, there is no attempt to convey a sense of the time. All the dialogue and character behavior is of our present day.
There were a lot of characters introduced over the course of the trilogy, and I didn't feel like we got to know many of them well enough. It was also a little difficult to keep track of them from one book to the next. I suppose if I read them all back-to-back it wouldn't have been as bad, but these are 300+ pages each.
I realize these books are targeted for young readers, but I found it kind of hard to swallow the idea that virtually everyone running the world is a teenager. There are some grown-ups, but most of them are ineffectual and have to be rescued (or conquered) by the kids.
One word about this book - supercalifragilistic. Read it. Read the trilogy.
This book started slow as a transition to a bigger world, but it is my favorite among the three and it ended well. Some old characters will be returning and a new characters will be either on Petra's side or against her. Petra's character really developed in this book and the choices she made is good and not annoying like most female characters in YA novels and who is always clinging to her love interest, but the romance is not heavy here, more on focused on friendship since this book is more targeted on children.
Now I really can't wait for the ending of Kestrel's and Arin's story in The Winner's Kiss
At first I was like NO they're being separated and you got to see more of Tomik and there was a moment there I liked him but then he started getting feelings and Neel.

The Academy is burned to the ground by the rebels. Neel tries to find out who poisoned him. Dee appears at the Roma court asking to be an ambassador. Petra talks to Sadie Neel's 'sister'. Tomik hopes to get an apprenticeship to Fiala. Neel figures out who is the assassin. He publicly gets the assassin to appear and try to kill him before just imprisoning the assassin.

Opinions: I think this book let me down. Just a bit. I mean...I still loved the plot, but there were nagging problems. The action was great. Really. This action was more than the action in both of the first two books combined. It was fast. It was gory without being creepy. I loved the action. Petra has gained abilities with that sword of hers. She can fight well. And, of course, there is a battle scene. I am a big fan of those types of scenes when the battle commences. The action is poured into that scene. Completely. Sword. Cannons. Ah. I just love those things. The action in this book was thrilling. I was kept wanting more. Neel turning into a king but still being the Neel everyone loves. I liked that. He didn't let royalty status change him. Neel was still Neel. Reckless. Impulsive. Stupid. But he did make some smart moves. Not the 'I'm letting an outsider destroy our globes' part. That was plain stupid. He made everyone hate him. At least give them a reason to like you. They don't like you in general. You practically ruined the Maraki. They have a reason to fight you. I hope he did expect assassins. Really. There were many reasons for Neel to be assassinated. But he didn't change. Most people take royalty for granted. Neel didn't. He didn't even want to be king. I admire that he did become king for Petra's sake. It shows he really cares. Tomik. He really stands up for himself in this book. He turns into someone the other characters need. The Gray Man gas in a Marvel thing. The sailing Fiala's submarine. He is needed. He seemed to be in the background for book one. He was barely mentioned. And in book two? Not much of a helper. He is someone who people need now. I think he deserves that. He deserves to be recognized for his accomplishments. I think, while Petra seems like the main character, Tomik is very important. He has magic. People seem to forget that. Petra seems to ignore poor Tomik and focus on the thief she befriended not her oldest friend. (Which is not a good move for Petra.) I didn't like Petra and Neel's relationship. Where is it from? Why doesn't the 'old friend' win? I mean...I adore Neel as much as the next reader, but I don't see the relationship. They barely know each other anyways. Where is the chemistry? I felt like there was nothing there. Yeah. You had a mental link. What now? It seems like just physical attraction here. Sure. They robbed the Cabinet of Wonders together. What next? In book two, they didn't do much together. They were apart practically the entire time. So why is there a relationship? I rooted for that in the beginning, but I think Petra is being an impulsive teenager without thinking. She really needs to examine her relationship choices. The ending. Oh man. That was rushed. Really rushed. I felt like it also didn't give enough. The ending is...boring. You're left with too many questions. What happens next? Who is king? Neel? Does Petra end up as queen? And the way things were resolved. Oh my goodness. Too quick. Rodolfo just conveniently lands on a sword? How... No. That's not possible. Why is there no showdown? No fighting? No revenge? And the Bohemian army just...gives up? No. That's not how things work. There has to be other generals, not just the one. The ending made me feel like nothing happened. It made me feel dissatisfied. I felt like this book didn't give enough story time to just one character. I like multiple narrators, but I want more Petra or Neel or Tomik. I got a description of what happened but not exclusively in one person's point of view. I wanted to see things through just one person's eyes this time. Maybe with some point of views from other people. Maybe it will be focused on Neel. Since he's king. Or Tomik! I would love that. I prefer Tomik now, even though I preferred Neel in the first two books. Tomik really seems to grow. Petra. Man. She just turns me off. She is more sour and reckless in this book. I really had high hopes for her. And she just failed all of them. Is this how teenagers are these days? How...disappointing. Petra at the end. Oh man. She really annoyed me at the end. She was back to being whiny. It was as if losing her magic lost everything she was amazing at. I mean...she's reckless throughout the series, but the Choice just tore me apart. Wasn't there a better way? I don't know...maybe just saying yes to marrying him and convincing him? Or poisoning his drink if you said yes to marriage? Come on, Petra. You can do better. I know you can. I swear...she's more whiny in this book's ending than I can handle. And mopey. Really mopey. I can understand that losing your magic might devastate you, but you have to keep going on. After all, that indirectly caused your father to come back to you. Be happier, Petra. Be happy in general.
Witty and funny, but also profound and reminiscent as well. I reread the trilogy because I had the first book from years ago and wanted to read something on my shelf. 8 years older and I still fell in love with the characters, rooting and relating with them in their struggles. It felt like sitting on a porch in the evening glow as someone dear to you pours out their life story with deep wounds and wondrous joys alike. You let the sadness sit in the silence with the two of you and let the tears fall past your smile. Your heart wishes their path had been easier, more peaceful, and leagues less painful, but they tell you even going back that they would face the odds 100x again for the ones who survived with them and to cherish the time with the ones who didn't.
Maybe I'm just grieving my own losses right now, maybe I'm healing my inner child, and maybe I'm cherishing the world as an adult at last. Who knows? Perhaps Astrophil. Thank you Marie Rutkoski for this series.
A solid finish to a marvelous trilogy. A really excellent read. The writing is elegant, exquisite even, yet flows very naturally and unencumbered. I was surprised by how much I enjoyed these books and the masterful story they tell. The characters are robust and fully dimensioned. The literary world is richly developed and convincingly integrated into real world history. I'm sorry now, in retrospect, that I did not read these aloud to my children but to myself (my most recent bike reading books). I'll have to add them to the list of things to read to them in the future. Finishing has given me that sense of loss and sorrow that books occasionally offer when I've grown to love the characters and I yearn to keep sharing their lives and their stories. I'm certainly going to miss Petra, Neel, Tomik, and Astrophil. Well done, Marie Rutkoski. Well done.
Again, a high three but not quite a 4. Petra started out just as annoying as in the previous book, but she definitely matured and became more interesting. Tomik had so much promise but was never given the attention I think he deserved - he could have been such a dynamic character. John Dee remained interesting and became much more sympathetic - he went from being a mysterious outsider to an actual human with a real stake in the action of the story. Overall, it wasn't exactly the way I would have chosen to end the trilogy but it was still pretty good.
Book III of the Kronos Chronicles "Petra Kronos's father has been transformed into one of Prince Rodolfo's monstrous Gray Men, and Petra is determined to save him." Love, faith, trials, friendship, rulers, intrigue, magic, mystical, trust, all wound up into one story of victory! I didn't read the first 2 books of these Chronicles as this book was purchased at a library book sale, (the other two books were not with it) it looked interesting at the time for the type of book my granddaughter might like to read.
A good ending to a great series. It got a little over the top violent with main characters being killed off (reminded me a bit of the Hunger Games) especially as it started out as a middle grade series. And I'm not sure if there were anything historical in this one which was the coolest part of the last two. And the love triangle, ugh. But I liked how that ended. Anyway, Lydia hopes she writes more.
I had to lower the rating of the first two books so that I could give this one the highest out of the three. This book is amazing. The emotions of the character are portrayed so well and you can feel what they are feeling whether it be fear, sadness, discomfort, love, all of it. The characters have matured so much from the previous books and I really fell in love with the characters in this book. The suspense and build-up are also really good. I recommend this trilogy to everyone.
More 4.5 than 5 stars but the series as a whole deserves it. A gripping book from start to finish. The author did a fantastic job in pulling all the plot strings together for the final battle and nothing was out of place. Top notch, believable characters. Too bad the payoff was so short. I wouldn't have minded one last chapter from Astro's pov.
Despite finding Petra almost insufferable at this point I pushed through and was greeted with an ending that I was a bit disappointed by (in a nit picky sort of way), but I still managed to like the plot. I'm also a bit embarassed to admit it took reading all 3 books for me to realize this series is Historical-Fantasy.
This entire series was a new world of adventure and wonders, filled with fantasy and the thrill of a hunt. I absolutely loved this series. I consider it one of my top three! Thank you, Marie, for creating such a beautiful and imaginative read!!
I like the overall plot of the book, but there was nothing that really stood out to me. And I was mad at Petra to whole time, her character felt very selfish to me.
Petra is trying to save her father after Prince Rodolfo transformed him into a monstrous Gray Man. The Gray Men make up Rodolfo's army and are superior to humans with their superpowers of speed, protective scales, and poisonous skin. A pinprick from a claw through human skin can kill a person instantly. The Gray Men have such a thirst for human blood they have lost their humanness and are killing machines. Petra's plan is to kidnap the scientist who created them and force her to create an antidote to turn her father back into a human. With the help of Neel, Tomik, new friends, and old friends, this entertaining read was hard to put down.
I didn't give this 4 or 5 stars because I thought the plot was more predictable and less original than the first two books. That is not to say there are no unpredictable parts. I didn't expect the martyrdom of one character. Nor did I expect the mind-link between two characters. However, Neel's assassin was easy to predict. And so was Neel's fate. What I missed the most was the world building. In the other books, Rutkoski ties in Renaissance history with historical legends like John Dee or mythical creatures like Ariel. That doesn't happen in this book as most of the fantasy world has been established in the first two books.
The book also follows conventions found in fantasy versus steampunk. I have read so much fantasy it makes the story easier for me to predict. Petra's storyline follows the reluctant hero who has turned into a killer of some sorts. Her fragile psyche is explored a bit and she is more cynical and reserved. The humorous side to her is seen less as she broods over all the traumatic events that have happened to her recently. I found this exploration of her being damaged from killing others interesting and one not usually found in plots. So often the character kills someone and doesn't think twice about it. Petra grieves about what she's done and it makes for an authentic character struggling with having to kill others. Prince Rodolfo is one dimensional and not interesting in this book. He's the Dark Lord ruthlessly bent on gaining power over land and people. The steampunk aspects include Tomik creating gadgets, Astrophil almost dying because the brassica oil needed to keep him running was destroyed, and a submarine housing a wacky scientist creating monsters.
There is plenty of action and internal changes with the characters. Neel is forced to grow up and become a leader and the author shows this transformation in him handling a land dispute with wisdom. As an orphan he does not side with factions and grows in his role. As mentioned above, Petra seems to be having some post-traumatic stress and is more withdrawn from those around her. Tomik continues to grow in his magical powers. A romantic subplot creates tension that the trio must overcome. It was fun to see some of the characters again such as Iris and Dee. Astrophil is still the mentor and my favorite character. New characters, Lucas and Zora, are spitfires in their own right and add a nice fresh touch.
The subplot of the romance didn't interest me. It seemed clear from the start who Petra preferred of the three so I never really found the situation tense as it should have been. I was more interested in the turn of events for Petra at the end and learning to be average. Seems like there's an open door to scoot through if the series doesn't want to end. The message of sacrificing oneself for the good of everyone versus one individual is explored and contrasted with other characters. Sadie is the foil to Petra's mission to free her father. While Sadie is thinking of preventing the extermination of her people, Petra is solely focused on her dad. She is forced to think of what it means to sacrifice for the group or not. Lucas and Zora are zealots who want change in the government from the oppressive Rodolfo, but their actions can be construed as duplicitous in light of Lucas's heritage. I like how Rutkoski mucks character traits and personalities to make them a complex bag of good and bad choices such as Dee and Lucas. The thread of choice and sacrifice is tightly linked until the climax where Petra has to make a "choice" with her magic. Make a choice to read this series. A satisfying conclusion to an intriguing series.

There is something different about this book: I bought it! And boy was it expensive. But it was totally worth it.
I've known about this series for about four years. I had absolutely NO IDEA that there was a third book. Why didn't anyone tell me? You guys!
The reason I bought the book is because my library doesn't carry it. I'm really glad I bought it, though, because I was really surprised at how good this was.
The Kronos Chronicles are based in the 1500s. In all of the Kronos Chronicles, John Dee played a rather large part. He may be one of my favorite characters. A younger version of Philip Bretherton is someone I'd choose to play Dee in the movies.
I don't know if the use of the name John Dee was a coincidence, or if Rutkoski was referring to the mathematician John Dee (who is Nicholas Flamel's enemy in The Secrets of the Immortal Nicholas Flamel by Michael Scott). The referral to John Dee would fit because he was born in the 1500s.
Favorite Lines: Arun pointed to Astrophil, who clung to Petra's shoulder. "And what, precisely, is that?" "I am a spider," Astrophil gravely replied. Arun lifted one brow. "If you say so."
