Spiderwick Cronicas: El Anteojo Asombroso

With their "true story" setup and breathless warnings "Go away/close the book/put it down/do not look," the Spiderwick Chronicles series contains an intensely absorbing world of mystery, faeries, and imagination. Each book is irresistibly appealing, providing snappy plot progression, and dozens of imaginative pen-and-ink drawings.
Life gets even more exciting--and kind of scary--for the Grace kids, as the strange faerie world they've just discovered blooms to full life around them.
