Lobisomem stands erect like a man. His fur is dark gray but he is clearly muscular underneath it. Two black eyes look straight at Luiz' chest. Right where the heart is. Luiz and Romeo are going to scout camp. Luiz is looking forward to moving up to the next level where he becomes wolf. But are wolves actually dangerous? Not unless there's talk of a werewolf, according to his big brother, Romeo. At night Luiz hears someone howling from the woods. Soon the Sandman is standing in front of Luiz carrying his black umbrella in his hand. Dark Creatures – The Sandman's Black Umbrella is the second book in a series about the Danish-Brazilian brothers, Romeo and Luiz, and is inspired by the Brazilian werewolf Lobisomem.
