Mister Book - Daniel Guerra - Bog

Mara's grandmother gave her a very special book with instructions to keep it safe with her most valuable possessions. Also told her that the book would be very useful one day, and to pass it on to someone very special like her. Mara forgot all about it. When she moved to her new house, she gave away lot of her old stuff to make room for all the new things she bought. Among those things was her old school backpack with the book inside it.
