Read Book titles with each letter of the alphabet. (articles like a, an, and the don’t count in the title)

If the book title starts with the series name it doesn’t count for that letter.  (Exception to this rules are Harry Potter and Percy Jackson, or any other book which the name is part of the title)
Example:
Doctor Who: The Stone Rose.
Would go in the S not the D.
Zodiac Academy: Origins of an Academy Bully
Would go in the O not the Z.
