Brigid Alverson, writing for the School Library Journal, has included MARATHON as one of it's Spring Graphic Novel recommendations. Here's the skinny:
YAKIN, Boaz. Marathon. Illustrated by Joe Infurnari. First Second. June 2012. pap. $16.99. ISBN 9781596436800.Gr 7 Up—Yakin tells the story of the first marathon runner, a former slave who carried vital messages between the rulers of Athens and Sparta before and during the Battle of Marathon. Although recommended for ages 12 up, this book has some violence and a (tasteful) bedroom scene that might make it inappropriate for some readers.
