Taming the Pooka, Celtic Tales of the Trickster Fairy [EPUB ebook] 
Magical Creatures, A Weiser Books Collection

Perhaps one of the most notorious creatures from the fairy realm is the ever-changing trickster fairy: the Pooka. A shapeshifter, the pooka can take many forms, including invisibility, although it most often appears as a terrible horse with eyes of fire and flaming breath. It can also appear as a goat, goblin, dog, or even a rabbit. Not inherently evil, their main task is taunting: they’ll take you on a joyride of terrifying proportions, shake you out of your current frame of mind, knock you out of your stupor with a swift kick. ‘Taming the Pooka’ includes tales of this monster’s mayhem—from such notables as W. B. Yeats and T. Crofton Croker, as well as Douglas Hyde. No one is beyond the cunning of the pooka!
