Your protagonist —and usually your viewpoint character—is your reader’s portal into the story and the story world. The more observant he or she can be (curious, dazzled, apprehensive all work well) the more enticing the story world. A protagonist needn’t be a genius or even educated (think Huck Finn),he does need to be accessible. Keep your PoV character searching, musing, wondering, remembering.After all, he or she is about to enter new physical and emotional territory.
