on Live Write Thrive:

Have you ever read a passage in a novel that made you cry? Stirred up indignation? Real terror? I am often moved by passages I read in both fiction and nonfiction. Masterful writers can wrench emotional reaction from me even with random passages.
We’re told to get readers to bond with our protagonist within the first couple of pages, something few writers can do well. Yes, we might get readers interested in our characters and even riveted by their personalities and actions in the opening scenes, but do we truly care for them? Depending on your genre and story, you might not want readers to care for your protagonist all that much (at the start).
As we grow attached to characters throughout the reading of a great novel, we care more about them. And that makes it easier for emotion to be evoked in us. All along the way, a writer must carefully manipulate readers’ emotion, in a deliberate fashion, to try to get them to feel what he wants them to feel.
