Is this supposed to be an allegory??? If so, I hate those! Please, if you are going to call it a horror or mystery, make it a horror or mystery. Otherwise, just put it in the general fiction category. I do not think that the missing sister and dinosaur aspect meshed at all. At all. It was unusual and I just couldn't get into the story. Also, why didn't they install cameras in the museum??
I did like Fran though!!
