After witnessing the shocking murder of his father, Leo Hightower must begin life on his own. For the typical twenty-one year old, that prospect would not be overly daunting. But Leo is not typical. He has "special needs" - the politically correct term meaning he is not normal. Leo is developmentally delayed, has a low IQ, and takes medication daily to help control his ADHD. He begins life as an independent adult in his own unique fashion: following strict regimens to accomplish daily routines; riding his bike long distances rather than enduring the near panic he feels when driving a vehicle; and relying on his dad's voice that Leo still hears inside his head to guide him. Along the way he touches the lives of others who are eventually able to look past his special needs and see his basic goodness and strength of character. Just as Leo settles in and begins to feel comfortable with his new responsibilities, he is forced to face unexpected challenges. Chief among them: His father's killer is now targeting Leo.
