Who would play them in real life?

So, I'm sure that you all know by now that I am a nerd and have been reading about writing a book. I mean, there are a lot of benefits to this. One of the things that caught my eye was one of the activities at the end of a chapter. It asked if someone were to turn your book into a movie, what actors and actresses would play the characters?

For the past couple weeks, I have really thought about this and have to say that this was one of the hardest activities yet. There are four characters who more or less run the story and five more who are considered "supporting cast" and are necessary to keep the story on track. There are a few more that fill in the holes and are almost as important as the "supporting cast". Of all these, I have only been able to identify four people that I could see (and hear) playing my characters and let me tell you, it's very frustrating and cool at the same time.

I think William Carson may have been the easiest person. Again, I'm not sure why that is, but I am not complaining. The hardest person to "cast" is Devyn Williams, the main character. In my head, she is the one who, on the outside, can hold her own because she feels that she has to, but has a past that she needs answers for. I wonder if it's because when I created her character, I may have given her too much of my stubborn personality or a tough side that I wish I had. Not quite sure though.
