How many books in the candy apple series?

There is no widely known series called "Candy Apple." It's possible that you're thinking of a different title or that it's a smaller, less well-known series.

To help me figure out what you're looking for, could you provide more information? For example:

* What is the genre of the books? (Romance, fantasy, mystery, etc.)

* Do you remember any characters or plot details?

* Do you remember any other details about the book cover or author?

With more information, I can try to help you find the series you're looking for.
