The Fairy Idol Kanon books are great for girls who love to sing. These books are all about three girls named Marika, Kodama, and Kanon. They love to sing and dance. Then a magical fairy named Princess Alto meets Kanon and decides to help start their singing career. Personally I think these books are for girls 7 and up and girls will really love these books. I was reading these books and I could not stop reading them. They were so good!
