I LOVE THIS!!!

This is a book about three sisters. When they were young they disappeared for a whole month and come bsck naked in the same street they disappeared, but they don't remember anything from the past.
They got strange abilities and they are not how they used to be, according to their father.
The book is full of mystery and unsolved mysteries.
The world building and the writing is genius. I was mesmerized by the story and characters.
The story is told by Iris, the little sister. She has an amazing character growth by the end of the book.
