The Secret begins with Annie and Cody wanting to know more about the mysterious "Sam" and about the men who helped search for Cody in the first book. So they go to Annie's parents house to demand answers to the questions they have. While they are there Annie's parents reveal the whole story, that includes Cody's parents as well. But neither of them realize that they could be in danger by learning everything. I have to say this one wasn't as good as the first one. But it was still pretty interesting. The whole story is pretty much Annie's dad telling the story about who he works for, and about Cody's parents. Including the fact that maybe they didn't die in an accident. But in the end we realize that Annie and Cody may now be in danger. I loved the first book, but again this one wasn't as great as that one. But it was still good.
