A delicate being with gossamer wings. Is this what you imagine when you think of fairies? Well if so, you may be in for a shock. Varla Ventura, the author of “Fairies, Pookas, and Changelings” suggests something else. She claims: “The kingdom of the Fairy is one of vengeance, thievery, trickery and wild creatures who wish nothing more than to steal your child, drown you in the bog, or spoil your best Sunday shoes. The woods are lonely, dark, and deep. You have been warned.”
