While examining various belief traditions across Europe and the United States, The Fairy Realm consults an assemblage of anecdotal evidence as to the existence of fairies and other creatures that appear in fairy tales - giants, ogres, trolls, mermaids, brownies, wildmen, kelpie, puca and other mythological beings. Ronan Coghlan, whose works include The Encyclopaedia of Arthurian Legends, Handbook of Fairies, Irish Myth and Legend and The Grail, examines an array of alleged fairy sightings in an endeavour to find where fairies fit into the modern scientific concepts of the universe. Unlike myriad books on ghosts and extraterrestrials, this book boldly tackles the possibility of fairy existence, and in doing so dares to approach all manner of sceptical argument.
