Book Challenges, Personal

Opinion (I Need Yours)

So I just quickly read Black is for Beginnings, which is the graphic novel 5th book of the Blue is for Nightmares series by Laurie Faria Stolarz (the first 4 are not graphic novels).

Do you think I should still count it for the Finishing the Series challenge?  It was never on my original list, but it is technically finishing a series I guess.
