Peep! — Kevin Luthardt

PEEP! A duckling breaks through its shell and immediately attaches itself to the first thing it sees―a warmhearted young boy.
The newly hatched duck follows the boy home and soon the two are inseparable. But the duckling is growing up. One day…QUACK! When a flock of ducks flies by the boy realizes with a great pang of sorrow that his friend will have to return to live among its own kind.
Kevin Luthardt's deceptively simple story poignantly and humorously dramatizes the special tale of friendship and demonstrates the importance of learning to let go of something you love.
