Intermediate books are designed for readers who have moved beyond beginner texts but are not yet ready for advanced literature. These books often feature more complex vocabulary, themes, and sentence structures, making them suitable for developing reading skills. They may include a variety of genres, such as fiction, non-fiction, and poetry, allowing readers to explore different styles and subjects. Typically aimed at readers aged 8 to 12, intermediate books often include illustrations and engaging plots to maintain interest. Popular series like Harry Potter or Percy Jackson are examples that appeal to this age group, providing both entertainment and opportunities for learning.
