Other boy-friendly authors include:
Matt Christopher If your son likes sports, you have to check out Matt Christopher, author of the #1 sports series for kids. He's written about everything from basketball and baseball to dirt bike riding and lacrosse. He's even written a series of non-fiction books about sports legends such as Dale Earnhardt and Michael Jordan.
Neil Gaiman An award-winning, living legend in the comic world, Neil Gaiman is perhaps best known to the masses for his book-turned-movie Coraline. Be forewarned, though: Gaiman has written everything from children's books to adult novels, and his themes can be a bit dark at times.
Shel Silverstein Is there a better way to introduce boys to poetry than through the work of Shel Silverstein? My four active boys actually begged me to read more poems when I sat down and started reading selections from Where the Sidewalk Ends during lunch. (Bonus: his website actually has some really cool activities for kids as well.)
Geronimo Stilton Apparently, some mice really know how to write. Geronimo Stilton is a talking mouse and the fictitious author of a wildly popular series of children's books aimed at kids ages 9-12. Would you believe that Geronimo Stilton is more popular in Italy than Harry Potter?
Do you have any favorite authors to add to the list? Who do your boys enjoy reading?
