This story was significantly darker than its predecessor. I still enjoyed the emotional journey, but because of the heavy emphasis on sex trafficking (implied but not explicitly shown), I can't recommend this book for children or teens without their parents having read it first to make sure the content isn't too mature for their children and teenagers. It would be a great conversation starter to delve into deep moral questions and topics. It's definitely eye-opening and heartbreaking that children around the globe go through such atrocities.
Content: sex trafficking (implied, not explicitly shown), nudity, medical procedures
FTC: I received a copy from NetGalley. This is my honest opinion.
