This has been said around here before, but I've learned firsthand it's worth saying again: Listen to your novel. Before you send your precious baby off to an agent, or before you hit Publish on Amazon, copy and paste your opus onto something like ttsreader.com and let that computer-generated voice have at it. Let it flow over you, without looking at the text, preferably while you're doing something else. It's amazing what you'll notice about words you overuse. You'll be made aware of whole chapters where the story just draaaaggggggs. You'll be disturbed--- in a very healthy way--- by the padding in your dialogue. It'll reveal to you where your sentences are awkward and convoluted, and catch the editorial ghosts. And of course, that little voice will mercilessly serve up the misspellings and bad grammar. Ouch, ouch, ouch. When I hear something awful, I stop the read-back, bring up the text file window, and correct the problem. It's not foolproof. Sometimes the voice will mispronounce words you have right. It won't tell you if you've misused a homophone. It never can figure out the difference between past tense and present tense "read" (red/reed). But altogether, the exercise has been valuable.
