   Summary

   Gillie is very bright. He was severely assaulted as a young child, and that has caused PTSD. He is a bit of a wimp and baby, but is gifted. Follow as he grows, and heads toward his teen years, having already graduated from high school at the age of 12, and college at 14, but he still looked like he was maybe 7 years old. His younger sister and siblings decide he is the smallest, so he is just a big baby, and so it goes from there. His parents seem to be embarrassed by him, so they take it out on him...
