This series for young adults (The Missing) sounded promising. I've enjoyed Haddix's books in the past. And I did get some satisfaction out of reading "Found" - the first book in the series. The premise of the story is interesting, but "Found" was not complex enough to encourage me to keep reading the following books.
The storyline follows Jonah, Chip and Jonah's sister Katherine as they come to realize that Jonah and Chip are not necessarily who they think they are. They may have been smuggled out of another time in history. There are opposing forces coming at them, including the FBI, and the trio has a hard time deciding who is really on their side. I can see this as an action science fiction movie.
