We had one category get 7 votes, one got six votes, two got five votes, and we had 5 that tied at four votes (more on that later).
The top vote getters were:
Fantasy/Sci-Fi/Paranormal/Urban Fantasy/Supernatural - 7
Mystery/Crime - 6
Published the year you were born - 5
Children's or YA book - 5
The five categories that each had four votes were:
Non-Fiction
One Word Title
Diverse Reads
Recommended by a friend/family member/collegue
Fanfic of at least 100k words
In order to keep us on track with our voting, I used random.org to choose the last two categories for this round. I numbered them 1-5 in the above order and then had the randomizer give me a number. Here's the result:

That means "One Word Title" makes the card.
I then renumbered the above list after removing "One Word Title" and consulted the randomizer again. This time the result was:

So, "Fanfic of at least 100k words" also makes the card. The other three remaining categories will go back into the list for the second round of voting.
That makes our final first round list look like this:
Fantasy/Sci-Fi/Paranormal/Urban Fantasy/Supernatural - 7
Mystery/Crime - 6
Published the year you were born - 5
Children's or YA book - 5
One Word Title - 4
Fanfic of at least 100k words - 4
These six books will make up the first six squares on the board.
Second round voting post will open shortly! Thanks to everyone who voted in the first round!
