How many times have you opened a book, read the first few sentences and made a snap decision about whether to buy it? When it's your book that's coming under this casual-but-critical scrutiny, you want the reader to be instantly hooked. The way to accomplish this is to create compelling opening sentences.

If you're writing a thriller, mystery, Western or adventure-driven book, you'd better keep things moving rapidly for the reader. Quick pacing is vital in certain genres. It hooks readers, creates tension, deepens the drama, and speeds things along.

In one sense, every character you create will be yourself. You've never murdered, but your murderer's rage will be drawn from memories of your own extreme anger. Your love scenes will contain hints of your own past kisses and sweet moments.

In fiction, a reaction shot is a brief portrayal of how your character reacts to something that someone else has done. In contrast to more direct character building, your guy doesn't initiate the sequence; he completes it. Exactly how he completes it can tell readers a lot about him.
