How many books are out so far? Isn't it 7? But two of them are in two halves, so technically its 5??

5 if you're American, 7 if you're from the UK.
Storm and Dance was split into two for some reason.
EDIT: Also two more planned books to go, so altogether there's going to be at least 7 or 9 depending where you're from.
