I'm not gonna lie....I was really nervous with how the author handled Jack Frost in the picture book that came out a while back. He retconned (changed the canon) some of Nightlight's story by changing Nightlight's story post-Golden Age and post-Pitch. In the picture book, Jack Frost did not meet the Guardians as Nightlight before becoming Jack Frost. He was simply by himself, not knowing who he was or where he came from, having completely different powers and appearance from his Nightlight days.
Cut to this final chapter book in the Guardians of Childhood series. There are even more changes from what the picture book made to Jack Frost's origin, and the name "Jackson Overland Frost" is never uttered once. That is once again an idea that William Joyce had come up with years ago but never implemented during his writing of the final book.
The book starts out with the single most confusing 1st chapter to a book of all time. I had just finished re-reading the 4th book, so I knew what had already happened. Then the 5th book starts out, telling me of a huge battle that cost the mortal life of Ombric (kind of), gave Jack a scar mixed with Pitch's blood, and told me that it had been a very long time (100 years or so) since Jack had even seen the Guardians since that battle, and several hundred years had passed since the events of the 4th book.
I was so confused, worried that I had somehow missed a book of some kind. I Googled the series quickly and, sure enough, there was no "other" book that I had missed. So, I had to put faith in the book to quell my worries and confusion. It took a while, but it finally gave me the backstory into that fated battle (if you're curious, it's the entirety of the black pages in the middle of the book).
I have a little bit of a problem with authors who come up with new things later instead of having thought of it early on in the initial introduction and fleshing out of these characters. I hated that there is suddenly a "Brotherhood of Nightlights", though Joyce explained this away by saying that none of the main characters knew about it until the Man in the Moon told us. This was just Joyce's excuse for not having included this fact earlier. The reason why it doesn't work so late in the series is because it gives Nightlight a lot of power, the ability to call down the harnessed star energy from the 6 other Nightlights who had become stars in distant galaxies. So, even if the main characters didn't know about it, how did Nightlight not know about it until a very convenient time? If the answer was already said in the book, I clearly missed it because the absurdity of it all was getting to me a little.
Another I problem I have started out with the very first book: Katherine has no personality. She's brave, smart, and clever, sure. But so are a lot of children her age. Joyce compared her a lot to the other children of Santoff Claussen, but they were younger than her and had not been raised by Ombric himself, so of course she would stand out a bit. Being an orphan, being raised by the magical wizard, it would make any kid wonder about their parents. But other than being just an overall kind and intelligent girl with a sad backstory, Katherine has no personality. Where are her faults? Her flaws? Her insecurities? She seemed to save the day more than once, and was treated like an equal among the Guardians despite the fact that she was like 15 years old without magical powers or weapons. I felt like Katherine was given quite a bit more than she deserved because she's not written to be a human. She's written to be a reflection of goodness, and that became so much more apparent in this book because of the Good-Night Kiss from the 4th book affecting Nightlight and Katherine so much.
But apart from the inconsistencies between the picture book and this book, and despite the fact that Katherine is as flat as a piece of cardboard (though her role in Ganderly is rather interesting), the thing that irked me the most is the fact that Katherine and Nightlight (sorry, Jack Frost) can somehow change their ages, so they can appear more childlike or like a teenager. This showed up way more than it needed to in the book and was an entirely pointless detail, just so the two characters can be the same age at the end. It really distracted me from the dialogue, because sometimes the two of them would grow younger or older (between 11-18 years old) while they're talking to each other. It made me want to roll my eyes. I adored the other books for taking a lot of risks and being extremely interesting. But this book had a lot of random stuff thrown into it, some of it acting like it had been there the whole time, and it started to get a little "busy." I had to decide which details to actually pay attention to, and which ones to disregard entirely. The aging thing I chose to disregard because it's ridiculous.
When we catch up with the Guardians in the beginning of this book (after the hundred year passage of time), we see some changes here and there, like North's and Katherine's appearance being seemingly older (is North immortal now? How does that work?). I liked the Peter Pan idea introduced in the 4th book, that Nightlight being immortal would force him to watch his best friend Katherine grow up while he remained a child. I loved that idea. It's bittersweet, because he could influence other children as they grow older, and cause entire generations to believe in him, to love him, to remember him.
But Joyce didn't want that. He wanted Katherine and Jack together, I guess. Why? How is it realistic to make Jack Frost be with a piece of cardboard? I wished there was a part of her that had to be molded, shaped, much like Toothiana and, more importantly, like Emily Jane. The theme in the 4th book about Katherine "being" Pitch's daughter, or just like her, should have carried over to this book by making Katherine have a similar arc, where Katherine had some sort of anger or impulse that had to come in conflict with Nightlight/Jack Frost, that would force her to make a decision to grow like Emily Jane or go down the path of vengeance and darkness like Pitch. But the comparisons seemed to end abruptly as soon as we as readers actually saw Emily Jane appear at the end of the 4th book. Her presence seemed to say "Actually THIS is Pitch's daughter. You guys don't have to worry about Katherine being his daughter anymore!" We readers knew she wasn't Pitch's real daughter, but the comparisons were still there. That is an interesting theme that Joyce should have introduced earlier on and continued to the very last book. Just one of many things Joyce didn't really unpack more to make his story more interesting.
So, the Peter Pan thing never happened. The Katherine - Emily Jane comparison never happened. A lot of stuff was thrown in while other things were not fleshed out enough. But, in the end, I liked how Jack Frost grew and changed. The book was all about identity, growth, and change. It was much more than a simple coming of age story because Nightlight's need to change came from a fear that Pitch would destroy everyone and everything Nightlight loved. His change came from the understanding that his role as a Nightlight was no longer needed, due to the fact that the baby royal he swore to protect during the Golden Age was already grown up. His powers changed too, being more elemental in nature. Nightlight as Jack Frost became much more mature, even a leader, coming up with plans and hiding secrets from the other Guardians (except Katherine, of course). He had to make difficult choices, ones that would force him to lose himself for the safety of others. It was Jack Frost's story, above all else in this book, that worked absolutely. Because of that, I believe that this book, despite its flaws (it has more flaws than Katherine's personality), is a great end to the Guardians of Childhood series. Not perfect, but pretty good.
Thank you, William Joyce, for giving us Jack Frost! He's great in the movie, but, in my opinion, even better in the book!
