Celestial Monsters is a great sequel to The Sunbearer Trials. While the first book was an action-packed race for survival and raised some very interesting questions about the trials, Celestial Monsters is the more mature and more critical sibling.
After the disastrous ending of the first book, Teo, Aurelio, and Niya embark on a road trip/quest through Reino del Sol to save their friends and the world.
Their journey is adventurous, exciting, and slightly hilarious. I loved that we get a glimpse of more cities and areas in this world because it is one of the things that I absolutely loved in the first book. I also loved how all of them learned to trust in themselves and their power while fighting Monsters and saving people.
The extra in this book is that we get a second POV, Xio. They (using they pronouns because they try using that in this book) are not exactly our favourite at this moment, but I think it's kinda genious. They are the most conflicted about how the gods rule their world, and they voice lots of valid points for change. They also think a lot about their actions and are one of the driving forces of the story.

Xio's thoughts are reflected in Teo's, who also discovers that there are a lot more problems with how the gods rule the world, trying to help the humans but also bringing their own drama to them.

Celestial Monsters is a real treat with lots of adventures, character development, critical thinking about the world, and questioning authority. It's about friendship and self-discovery. It has a bit of romance, lots of battles, hilarious situations, and an epic storyline. Both Teo and Xio learn a lot and show a different side to them.
I immensely enjoyed this book, and the audiobook is awesome❤️
