Summary: Cordelia, raised by squirrels in Central Park, leaps into a new world when she discovers a gymnastics class. Her squirrel upbringing makes her a natural gymnast, but can she navigate the complexities of human friendship? As she balances between her wild roots and the desire to connect, Cordelia embarks on a journey to find her place—not quite a girl, more than a squirrel. Will she make a friend, or remain an outsider in both worlds? Join Cordelia as she discovers what it truly means to be 'squirlish.'
