If you are a fan of Rick Riordan's Percy Jackson series based on Greek mythology, you will be excited to know that the movie of book one, The LIghtning Thief, will be released in theaters on Friday, February 12.
While often checked out, the entire series is available at the public library in both print and audio formats. You may also want to check out some of the original mythology that the characters are based on in J 292.2, the juvenile non-fiction section.
For Greek mythology fans, there are several other fiction series based on Greek myths, including series by the following authors: Julia Golding, Mary Pope Osborne, and Jane Yolen.
I just read a graphic novel (comic-style book) which has received excellent reviews: Binky the Space Cat by Ashley Spires (JFG Spires). Making excellent use of this format, the story has very funny pictures and features a housecat, Binky, whose dream it is to save the world from aliens....but settles on "saving" his own humans from the small aliens that fly around their house (bugs!)
A shorter story in the same spirit as the Hank the Cowdog series, this is a good choice for beginning chapter book readers, or just any reader who enjoys a funny story with a charming hero.
