My seven-year-old daughter loves reading mysteries and my brother bought her several books in the Geronimo Stilton series. She loves them all! The stories are engaging with interesting plots involving mysteries and puzzles to be solved. The characters are engaging and fun for kids to read about and relate to. My daughter, a visual learner, loves the illustrations in the books as it makes reading a more engaging experience.The stories are well-written (I usually preview the books she reads before she reads them so as to ensure the books are pitched appropriately for her reading level and contain suitable content for her age). This is a great series to motivate young children to read, and keep on reading. There are two types of books in the Geronimo Stilton series - paperback chapter books and graphic novels. They are both great for independent young readers though I'd recommend the graphic novels for visual learners.
