The book has a purple cover and the title is something like "Wind" Ive Googled and can not figure it out. The girl is at camp I think and she goes somewhere shes not supposed to with her 2 friends and they wake up on a beach. They're from Texas. A dark skin and dark hair guy finds them. There are different tribes that control elements. She has wind powers. They think she's a prophet die to her hair and eyes being light. She finds out her dad used to be a leader. The current leader is evil
When she gets back to normal world barely any time has passed even though she was in the other world for days. At the end of the book she says that she needs to go back. She likes the guy that finds them. And she rides a giant dragonfly in one part.
