Sell my Ebook of Puzzles and Trivia

I have an ebook filled with puzzles and trivia that I am looking to sell. It is suitable for both children and adults and includes a range of different puzzle types such as Word searches, Crosswords, Sudoku, Flag trivia, Picture Trivia, QnA, and other related puzzles. I am looking to focus my marketing efforts on social media channels in order to get the most bang out of my buck and reach the widest audience possible.
