Fantasy stories are also a great alternative. 'The Lord of the Rings' takes readers into a magnificent fantasy world filled with magic, heroism and friendship, which is far more positive and engaging than inappropriate content.
Historical novels are another option. 'War and Peace' not only gives a detailed account of historical events but also delves into the human psyche during times of war and peace. Reading such works can expand your knowledge and understanding of different eras and human nature, rather than indulging in inappropriate reading materials.
You could read some heart - warming family - themed stories. For example, 'Little Women' shows the growth and relationships within a family in a very touching way.
