This is such a frustrating read to me!
It looks like Shane finally graduated from applying sheer dumb force to something more intricate, like a prolonged time-out. Took him full 43 years. Congrats. I am certainly happier for Gilli. It's not always about pain and humiliation. And please, check the boy for ADHD, someone? I am really bent on it, as my closest friend has a son with those exact symptoms and he is on some interesting meds. Sweetest kid when his condition is contained.
OK, it's only a book. I shouldn't take it so close to heart.
