The Glass Castle (Thirteen #1)

The king is growing old and is concerned about who will replace him. His new wife wants to produce an heir to the throne.  The only problem? Thirteen years ago, the king’s first wife gave birth to a son, and no one knows for sure what happened to him. Rumors swirl throughout the castle. The solution is simple: dispose of all the thirteen-year-olds in the kingdom. Except, it isn’t that easy. Avery and her friends won’t go quietly.  

Avery, Kate, Tuck, and Kendrick take charge of the underground network of kidnapped children, inspiring them to believe that their past does not dictate their future and pledging to do the hardest thing of all. . .reunite the children with the homes they left behind.  When they discover that one among them might be the child of a man who wants them dead, will everything they work for be lost?
