Leprechauns are always interesting, and there are plenty of books about them. If you haven't had enough, you might like How to Catch a Leprechaun, by Adam Wallace, or A Fine St. Patrick's Day, by Susan Wojciechowski, or Too Many Leprechauns, by Steven Krensky. A classic tale is Jamie O'Rourke and the Big Potato, by Tomie dePaola.
If you want to know more about the history behind the holiday, try Shamrocks, Harps, and Shillelaghs: The Story of the St. Patrick's Day Symbols, by Edna Barth, or St. Patrick's Day, by Carmen Bredeson, or The Story of St. Patrick's Day, by Patricia Pingry.
May you always find the book you need, and enough light to read it by.
