How does this figure into The Experiment? Especially since hardly any of the children are orphans? Well, they are treated as such. They even go to an orphanage at Courtstone. They are put in dormitories, given ugly gray uniforms, fed nasty food, faced with the possibility of being separated from their siblings . . . it's just what orphan stories are made of. I want to write a true orphan story someday, but since I haven't yet, I have to be content with the orphan story elements in The Experiment.
For any others who enjoy the drama of orphans, I highly recommend Thursday's Child by Noel Streatfeild. It is one of my favorites.
