Harry Potter and the Order of the Phoenix has been nominated for best fiction in the WH Smith Book Awards.
Normally books for children aren't nominated in the fiction category, but a spokesman for WH Smith said it's more of an adult book than the first four.
JK has a good chance of winning, as the award is voted for by the public.
Other important books have also been nominated, including another kids' book, The Curious Incident Of The Dog In The Night-Time by Mark Haddon.
