Small issues of the series hangs throughout, namely sparse descriptions of the characters.
However, the story is very solid, and I quite liked how this final book wrapped up each character.
The action is engaging and essentially nonstop in this book. I think some parts can feel just a touch cheesy (in a "we're all in this together" kind of way, haha), but I don't think that's necessarily a bad thing.
There's a part of me that doesn't quiiite sit right with the consistent notion that all carnivores are inherently evil. The carnivores are, for the purposes of the story, monsterously evil, but I think it would have made for a bit more of an in-depth and rounded story had we gotten a bit more from carnivores outside of them just being bloodthirsty and power-hungry. That being said, I do understand that realistically, herbivorous dinosaurs would have no feasible future living with carnivores.
So, consider that really my one little, tiny nitpick of the overall plot.
A small thing, really and I tend to be iffy about pointing this out since I think it should simply be the norm in books like these, (but we live in a time where it unfortunately isn't the norm and thus, should be given flowers when it feels right to), especially in children's literature when it is possible: thank you for adding queer characters, even despite being relatively minor.
Children's literature needs characters like Olithine and Jorela: strong, warm, openly queer characters without becoming a caricature of queerness. They just: are. They exist, are in love, and provide a strong, supportive foundation for the main cast, and I think that is wonderful.
While they are minor characters, they have had a large presence since introduced, and aren't shoved to the back nor buried.
I personally love a story that doesn't overstay its welcome and wraps up neatly, and this trilogy did a wonderful job of doing just that!
While I would gladly read more stories in this universe, I feel very satisfied with the ending; a very nice sweet spot for a book series to be in.
