Fox needs the best socks. Not smelly socks, or socks with holes, or mis-matched socks. Fox shows off all the wrong socks before finally finding the right pair.

"In his debut picture book Sock on the Loose, author-illustrator Conor McGlauflin takes you on a fun, sock-filled, adventure about finding yourself and discovering your way back home. Socks come in twos, snuggled up in your shoes. At night they sleep tight, matching pairs in a row. Until--wait a minute!--oh no! Where did Blue Sock go?... After its twin doesn't come back from the wash, Blue Sock decides it wants to explore the great big world outside...

Little Sock returns to the excitement of Sock City, where he soon realizes that the adventure would be more fun with a friend, if only he can find one.
