At 13, one passes from childhood into teen-hood. For Malakai Ian LeCrue, turning 13 also means coming into an inheritance he wants no part of. But someone has to take up the mantel of Sentinel, passed down from generation to generation through Kai's family. He hopes this tell-tale mark will simply pass him on by. He has none of the qualifications needed to become part of the secret Sentinel Society. Not like his little 10-year-old sister, Wyndee, who is a regular scholar of Weirdology.
