I enjoyed this book a lot. It wasn't the best book I've ever read but neither was it the worst. It's an adventure story. Nothing too special happens in the plot at all. Two kids go on a journey to stop the sultan from killing off innocent girls and destroying their town. That's it. The plot is fairly simple and so is the writing. The characters can be hit or miss. In fact, I didn't quite care for any of the characters aside from Khalila and she's not even one of the main characters. All the other characters kind of got on my nerves after a while.
This book is something you'd want to read if you don't know what to read and you're just craving a simple adventure story. However, the ending does not tie up all the loose ends and there's no sequel so if you're a reader who likes closure, you might want to skip this book. Otherwise, give it a try. It's an okay read.
