Kaytek the Wizard
Janusz Korczak
 The book depicts a schoolboy who gains magic powers. At first, Kajtuś acts as a selfish child, using his power for mischief. Eventually, he becomes dissatisfied with himself, and leaves his home town, where he acquires a reputation as a troublemaker. On his travels, he meets Zosia, a girl who uses her magical power for good. Together, they fight an evil wizard, and Kaytek chooses the path of a good mage. The book contains some gaps, including one of the chapters, which were sections that were crossed out because they were too frightening to children.
