Specifically, if you were to swing a massive textbook at full strength, would it break upon hitting someone's skull? Assume a thick high school textbook, that looks like one of these: And, if it doesn't break, could it shatter someone's jaw? Break their nose? Basically, how bad is this to be on the receiving end of as a blunt weapon? I ask this because a character, from side effects of an experimental drug, ends up smashing a bully's face with a textbook, and continues to until the book breaks. Well, that, and I feel like big heavy books like this are something a lot more characters will have access to compared to say, a gun, or even a knife, depending on the context.
