Book one of the Billy Buckhorn series introduces a Cherokee teen who uses his supernatural abilities to solve mysteries. In Abnormal , Billy is struck by lightning while fishing with his friend Chigger. He survives the lightning strike but begins to experience an enhanced level of ESP. Billy is labeled "abnormal" by one of his teachers after he uncovers an unsavory secret from the teacher's past. What no one suspects is the teacher is a shape-shifter who becomes a raven that gains strength from his victims' fear. When Billy confronts the teacher, he must channel his own fear into anger in order to defeat the evil raven.
