Read 26 books, each beginning with a different letter of the alphabet. The words 'A' and 'The' don't count (unless you want too) as the start of the book title. 
Example: For A- Ans then there were none
B- Better than the movies and so on.   Here's little tip, if and only if you can't find books from letter X, J  or Z or any other rare title letter, you can add books where the letter is anywhere in the title. Doesn't have to begin with it
