Ángeles, by Paula Markovitch
Ángeles is a twelve-year-old girl, sweet and fierce. She sells candies on the street with her sister Isabela. David is the caretaker of a parking lot. The three of them often hang out and listen to music in the parked cars. One afternoon, David confesses to Ángeles his decision to kill himself by jumping off a building. Instead of trying to dissuade him, Ángeles decides to help her friend.
