I read the teen book series on which this new TV series was based, and am a bit disappointed in the show. The four books could have provided at least four good episodes to start off (or even more), but were largely ignored.
The series, which premiered on Lifetime Channel on August 2, 2003, skips most of the events in the book, leaving out the father and barely touching on her mentally ill brother, completely ignoring her long battle against the FBI and the team of psychics she eventually works with at the very end of the book series.
So, the show is only vaguely related to the books. Yes, she is a psychic who gained her powers after being hit by lightning and finds missing people in her dreams. But don't expect to see anything from the books.
Casting for the main character is good, any other casting is immaterial since none of the other characters from the book are in the series.
It is unclear if they intend her to be the high school student she was in the books, or if she is college age (as is stated in the series, which may have just been a smartass comment and not her "real age").
Overall, the new series is worth watching, if you like psychic cop shows. If you liked Profiler, you will probably like 1-800-Missing. It has a similar feel, with a *much* younger heroine.
