I read this book because I was trying to complete an alphabet challenge and needed a book with a title starting with the letter Z. I didn't think I'd love it, and I was right. The book does read quickly due to the simple sentence structure. The characters are not deep. The plot is fairy tale Rapunzel, without shying much away from the darker elements of that story. The portion where Zel has lost her mind in the tower is pretty disturbing, I had to skim through it.
