I have a lot to say about this story. First, it doesn't seem realistic at all. If I got a call from someone at the FBI and my husband didn't come home the night before, I would be freaking out. She is way too calm. Secondly, the character's aren't fleshed out at all. I know nothing about the daughter or the son except that they sound really annoying. Also, the mother never says where they are going and why. This peice needs a lot of work. There needs t be more detail, more emotion. You need to egage your readers and make them want more. Work on making the dialoge much, MUCH more natural.
