Interesting Magical story!!
The first thing I notice is the synopsis reminds me of the Winx Club vibe, if you are familiar with it. Haha. The TV series will be coming on Netflix. And when I glance at your book cover, yasss that's right something fairie and magical about the story.
Now, let's see the writing syle. I like how you have a clean writing style, which is on the point. But you may want to take a look at how you write a punctuation. It will be easier for readers to read when you put a period instead of a coma if the sentence is too long. You can break a long sentence in two or three sentences. See your first two paragprahs in the first chapter.
Overall, this is a pretty interesting reading for magical realism lovers!!!
