"Bernadette and Rodney are the best of friends. Rodney's not so good at playing cards, but he's great at staring contests. His favorite food is lettuce, though he eats it VERRRRRRY SLOOOOOWLY. And he's such a joker! When Bernadette goes to sleep at night, Rodney is always there, watching over her from his tank. As the seasons pass, Rodney moves slower and slower, until one day he stops moving at all. Without Rodney, Bernadette feels all alone. She can't stop thinking about him, but none of her friends seem to notice. Except for Amar. Rodney Was a Tortoise is a moving story about friendship and loss. It shows the importance of expressing kindness and empathy, especially in life's most difficult moments."--,Front jacket flap.
