Very gripping book about a 6-yr-old named Matt who is abducted from school by the emotionally troubled father he has never met. His 13-yr-old sister Bonnie recognizes Matt & her former stepfather in the crowd at a baseball game and must quickly decide how to rescue him without putting either of them in danger. Matt and Bonnie try to get help on several occasions but everyone assumes the kids are playing a prank. I DO think the author got a bit heavy-handed at the end when all those people see the news later that night and realized their mistake. I think the point was made quite well already without revisiting each of them.
