Meet Aleta. She has two best friends, Cassie and Nina, and she wants to be a vet. Aleta knows that animals don't live forever, but when her dog Kate dies, she can't believe it. It just feels so unfair! And she doesn't want to talk about it. She wants to be alone, and she's really sad and a little angry, too. With the help of her family and friends, Aleta learns to deal with her feelings and comes to be able to remember Kate with happiness.
