This book is the third novel of the Shadow Children series. While the first two books are from the viewpoint of a boy named Luke, this one is different. It is tolled through the viewpoint of a girl named Elodie Luria, who goes under the assumed name Nina Idi. This character was arrested and imprisoned along with several other suspected "shadow children." In order for her to be spared, she must get the other children to confess to being third born. This book is just as intriguing as the first and second book. This book teaches the reader about what it means to fight for a cause that one believes in. This is also relevant to today's time. The most recent events I can think of is the controversy over the President and gender laws. Many people feel strongly for or against both items. Students will need to start learning what it means to believe in something and fight for that belief. The book provides an excellent basis for building the foundation for understanding what it means to believe and fight for something. Despite this lesson not necessarily being academically biased, it teaches about the importance of a person's ethical and personal beliefs. This book has a lexile level of 690L so it should be used in the 6th grade and above.
