The Sky Overhead, aka Redundancies

Another thing to watch for in your final draft is redundancies, the "unnecessary repetition of meaning*." Some examples are: stood up, sit down, murmured softly. (*From The Handbook of Good English by Edward D. Johnson.)

Redundancy also means repeating information throughout the book. As a reader, I don't want to be told the same information on page 10, 25, 75, and 150. As a writer, I know that in a 400-page book, it can be difficult to remember what you wrote a month ago, or last year, depending on how long you've been working on your book. By the time you've gone through your manuscript several times, it's even harder. You won't know for sure if you wrote the same thing several times, or if you just read it too many times. You might have to ask a fellow writer to offer a fresh set of eyes.
