Today David and Saba are building a machine from scrap in the cave of Ali Saba. I have to do it. But Sabata is troubled by all this: what machine do David and Saba Bonim actually use? What will she know how to do in the end? Erez Haddad, screenwriter and director and father of four, tells in his first book for children about an exciting little journey that takes place one afternoon at his grandmother's house. A journey in which past and present, reality and imagination are intermingled, and there are moments of pure pleasure on both sides, pleasure that has no equal. Abiel Basil, a master illustrator (son-in-law of the Israel Museum Prize for Illustration) and father of two daughters, gave the book illustrations full of emotion, warmth and humor.
