In Building the Hook, I talked about writing your pitch paragraph so it reads like the back cover of your novel. Here's another reason why to follow this advice.
Publishers send novels to reviewers. Stacks of them. Truckloads of them. They fill up the coffee table. The garage. The living room. Next thing you know, the reviewer has to buy a second house just so he has a place to put all of the novels he is reviewing.
To narrow down the list and maintain their sanity, reviewers read the back cover copy to determine which novels they will and will not review. And the same thing goes for agents. They get so many query letters that many will use the pitch paragraph to determine which authors will get their attention. Make sure yours stands out.
You also might try writing the pitch paragraph--the back cover copy--before you even write your novel. Not only will this help you focus your novel on the plot catalyst, but it will force the pages to live up to the hype. If your story changes direction, simply rewrite the pitch paragraph to fit.
