The Rules of Survival

I am reading a book called The Rules of Survival. I have only started the book but I have read and it is about these 3 children and their mom is never home anymore and their dad is never around. The 2 oldest kids go to the store and this other kid is there with his dad and he got in trouble and the dad was about to hit the kid but another guy stepped in and he told the father to hit him instead of the kid.
