"Help me find my little girl." Jess Mastriani — dubbed "Lightning Girl" by the press when, after a huge storm, she develops a psychic ability to find missing children — has lost her miraculous powers. Or has she? She would like the media and the government to think so. All Jess wants is to be left alone, by everyone except sexy Rob Wilkins — who still hasn’t called, by the way…. But it doesn’t look like Jess is going to get her wish — especially not while she’s stuck working at a summer camp for musically gifted kids. Then the father of a missing girl shows up to beg Jess to find his daughter. Jess can’t say no, but now the feds are on her trail again, as is one ornery stepdad, who’d like to see Lightning Girl…well, dead.
