In case you’ve ever wondered where missing socks go on laundry day, Carnegie Medal awardee Jason W. Thurston of Northport, Maine, has solved the mystery: They escape through the vent to cavort in the land of the free, just past the plant, hidden by trees. Or so he posits in his first children’s book, The Missing Sock, which he wrote and illustrated this year. The eBook is available on Amazon.com. Thurston, who has a background in graphic design, illustration, and art history, was awarded the medal in March, for rescuing his elderly neighbor from her burning home on Christmas Eve in 2010.
