Simple Lessons — Charlotte Bennardo

Jack, a common gray squirrel, has learned some of the simple machines. Taught by his human friend Collin, he's chased construction machines from his wood, and saved his friend Rat who was captured by scientists looking for Jack. The scientists show up at Collin's house. Worried for Jack, Collin takes Jack to an animal sanctuary, where he meets other squirrels and animals. But soon the scientists show up again. Jack, with the help of Addy, a female squirrel, and other animals, wage a last battle. For Jack it will mean he'll go free-or be caged forever.
