Many would have you believe that sprites (or "fairies" as they're often called) are sweet and pretty and ultimately peaceful creatures. But don't let the carefree nature of these dazzling beguilers fool you. Because while they do make for awesome pets (or, if you prefer, companions), these are not creatures to be handled lightly. So forget everything you know -- or think you know -- about sprites, and listen to the experts from the International Sprite League as they, with the assistance of the creative team that brought you the bestselling Spiderwick Chronicles, provide a resource that will prove to be as essential for the novice sprite keeper as a strong cage and eyes in the back of his or her head.
