Written by Telma Guimarães, author of the best seller Where is the book that was here?, this oral tradition narrative presents the story of a jaguar that goes after children who stay awake at night. Full of delicacy and emotion, the story refers to popular lullabies from the oral tradition that are part of our imagination since childhood. The illustrations, by Isabela Santos, expand the tone of the book, creating an ethereal sensation, almost like a dream, using light and shadow as main resources.
