Leprechauns and Irish Folklore by Mary Pope Osborne and Natalie Pope Boyce contains a lot of fun and interesting facts about the Celts and the old legends of Ireland. It addresses historical events that have affected Irish folklore, such as how Christian monks came to Ireland and documented many myths, how English heritage almost wiped out Irish folklore, and how if it weren't for people like Douglas Hyde and Lady Gregory, the amazing legends of old might have been lost. Most of all, this book tells of fairies, all kinds of fairies, such as leprechauns and banshees. This mind-boggling research guide includes everything from how fairies act and where they live to what fairies like and how to prevent their mischief. Stories are told about peoples' encounters with fairies, how they can be very nice or very dangerous. You even get to read about the origin of Halloween in Ireland. Later, the book tells about a magical land filled with fairies, where you never grow up. Finally, this book cautions that you never know where a fairy might be hiding!
