Is there still enough time to read the 7 Harry Potter books in time for July 15th?

depends, if you are a reader in general, but at the same time it doesn't matter. Cause I could read those books soo fast cause it was hard for me to set them down. and i read them before the movies came out. so knowing the movie and reasding and expecting something might slow you down. or speed it up. just try to do it.
