I specifically asked the library to get me the 90s print because of my issues with the 00s reprint censoring some dark topics and making the girls cousins instead of sisters, but they sent me the reprint, so I lived with it. It's the same basic story, the new designs are still very cute, some of the world renaming details are fun, and this is the last book that even got a reprint, so we're going back to sisters next book.

Either way, I liked how this dug into Demetra's character arc. I remember her being the most memorable to me as a kiddo because she's the bossy stickler, and the crux of the book is her relationship with Finley - her advisor (a white fox) who is equally headstrong. The two of them hurt each other's feelings a lot and have to learn how to be more vulnerable in order to really connect and care, and it's Demetra who needs to make the first step because, as we learn, she has started most of the fights. Of course, they go on a bonding adventure and come out stronger friends at the end, and my heart is warmed.

The White Winterland is a cool fantasy concept, but I would hate to be the one stuck running the cold area. Props to Demetra for that. I also want to give kudos for this book having goblins be normal citizens and good people who need to be protected. I don't mind when other books use them as villains or tricksters, though it can get problematic. It was so refreshing to just see good goblins, though. Stop besmirching the goblin name! It's 2026!

My biggest complaint is that for four books now, they have dangled Lord Bleak in front of us but never had him put in an appearance. This guy broke the world. I want to see what he's like as a villain.

Anyway, where's my Charger and Bernard spinoff series where it's a two-thousand-page epic about their work fighting Bleak together? I kid, I kid. Unless...

This book suffered from a much less interesting plot as the prior ones in the series. The dialogue seems to have improved and I am currently under the impression that the diamond princess' mirror is the most useful of all the princesses. I like the Ruby Princess for being bold and brave and the Sapphire Princess makes for a good character as I found her mostly defined by her kindness and ability to be friends with anyone. The Diamond Princess, however seems to be overshadowed by Finley, a non-princess character. Finley is quick witted and drives the narrative and so overshadows other side characters that I was more drawn to him than the main character.

This is another fun addition to this series that I’m preview in for my 6yo dahlia. I loved Demetria’s bravery in this one.

There was a single line about 3/4 through the book that I crossed out though. It’s when they said that Bleak used to be handsome before he become evil. It’s totally unnecessary to enforce the stereotype that ugly is evil and beautiful is good. There was a more subtle bit of that in book #2 as well.

I’ll add my daughter’s thoughts once she reads this.

My daughter and I blazed through this whole series. The Diamond Princess was her favorite of the 4 princesses and this was the book she most looked forward to, but she didn't enjoy it as much as the others. I think the strained relationship between the princess and her advisor didn't really resonate with a 9 year old. Still, it was nice to hear about the Jewel Kingdom. It's a fun series.

Aww !! I really like this story and how it dealt with the stubborness of the Diamond Princess and her advisor! Also the monster that wasn't really a monster and had such a tragic backstory... which is dark for a kids book!! But loved the use of the magical objects that is unique to each princess !

This was the only book in the series that I read as a child, but I was OBSESSED. I read it a lot. I don't know if it's bias or if I truly just feel this is the best book in the series openers, but this is the best for me having read all four. The aspects of friendship and working together are well done.

I'm wondering

I was wondering I know that I read this book as a child and all the characters were white I looked it up so that I knew that I wasn't imagining things. I am happy for the change though I love diversity in books

I read this series as a kid and I wanted to re-read them just for the fun of it. They're simple, but cute.

I like this book because there are diamonds and it's kind of weird because there was a scary bear and then it became a bear that was nice.

This book finds Demetra, the Diamond Princess of Winter Wonderland, on an adventure with her palace advisor – a talking fox named Finley – to save some of her subjects who have become trapped in a scary mountain cave. Demetra and Finley had a fight prior to the beginning of the story but soon learn that if they are going to save their royal subjects, they must work together. Along the way, Demetra and Finley learn about bravery, perseverance, friendship, and humility. The book features beautifully cute artwork that pairs really well with the vivid imagery used in the plot.
The story of Demetra and her journey is very simplistic but really drives home the themes of friendship, teamwork, and bravery in ways that are easily understandable for young readers between 2nd and 5th grade. The character of Demetra is very relatable as is her relationship with Finley. The text uses vivid imagery with a focus on color and texture that help build an image in the reader’s mind of what Demetra is experiencing on her journey. There are also many instances of alliteration throughout the story – such as “Big Bear Bernard,” “Magic Mirror,” and “Winter Wonderland” – that could be used as examples for students. It also has multiple instances of rhyme as that is how Demetra and Finley communicate with her Magic Mirror. These aspects of the text could be used as students transition from only reading narrative to learning about poetry as many of these forms of language are more common in poetry than prose. Students could be asked to look for alliteration and rhyme within a context they are familiar with.

This is the 4th book in the Jewel Kingdom series featuring Demetra, the Diamond Princess. The plot in this story is extremely simple, Demetra and her adviser Finley (who's a cute arctic fox) do NOT get along and have to go on a small adventure together, to save a bunch of goblins trapped inside a mountain. They learn how to work together and solve out their problems, and in the end, become really great friends.

If your child can read at this level it would be a good book. A fun beginning fantasy series. The plot lines are simple and easily solved with not too much of the dark side of fantasy.

This one was better than the second book, but none of them were as good as the first.

Read this in about a half hour. I can't believe I got so involved in the story when I was little. Now I realise there really is no story to get involved in, at least for my age.
