I read this book in probably 2021 and it was written by a teenage girl. The book starts of with the main girl getting kidnapped by this gang group (their name resembled the word Oreos or something). She gets saved by this guy that makes a portal out of rocks and they jump through to this sort of fantasy land. And she goes to school there and learns about her powers and whatnot. Then she finds out that her best friend got taken by the gang so the main girl sets out to go save her. I don’t remember how the book ends. I think the cover was the girls back with wings.
