Charlotte's Web by E. B. White
Wilbur didn't want food, he wanted love. He wanted a friend - someone who would play with him. One spring morning a little girl called Fern rescues a runt and names him Wilbur. But then Wilbur is sent to live on a farm where he meets Charlotte, a beautiful large grey spider. They become best friends and, when Wilbur is faced with a dreadful fate, Charlotte must find a very clever way to save him.
