While listening to Terry Goodkind's "The Nicci Chronicles #1" sequel to his "Sword of Truth" series something was said about misunderstanding, misconception, misinterpretation or misperception of information, what is not important

I'm pretty sure that the story was here at BCTS

Story:- Fantasy, involves magic and mythical beings
Setting:- Modern World (I think)

Scene:- Protagonist's elder sibling jumps in front of the attack of the younger and gets hit
