One of the most important things when writing a novel is to make your readers feel empathy for your main characters. If the readers have no reason to like a character why should they keep reading?
I couldn’t get past the first fifty pages of ‘To Kill A Mockingbird’ because I just didn’t care about any of the characters in it and none of them seemed real!
There are many ways in which to make your readers feel all emotional and shit like that, you can make one of the characters sad about something or you could make one of them really frustrated about something in the news.
But if neither of the these two example make you want to reach for a tissue then I suggest giving all of your characters a limp. Who doesn’t feel sorrow for people with limps??
