Book Buddies: Roger Takes a Chance - Cynthia Lord - Bog

"Roger the chick almost never gets the chance to do things on his own -- he's always attached by Velcro to his mother, Olive the hen, who prefers a quiet nap to any excitement. The two Book Buddies even come as a pair when they're borrowed from the library, so Roger doesn't go on many solo adventures. One day, a boy named Liam is persuaded by his little sister to borrow Roger and Olive before picking up Grandpa from the airport. While Liam is preoccupied with showing Grandpa how grown-up he is, however, Roger the chick wriggles free, only to be accidentally left behind. Could this be the chance that Roger's been waiting for, or will his airport adventure -- complete with a too-playful dog and a looming top of the escalator -- prove too exciting even for him? If Liam admits his mistake, will he have a chance to show how grown-up he is -- and help Roger get back from the Lost and Found?"--
