Many young adult novels include animal companions as “characters.” My favorite example of this comes from a Garth Nix trilogy (Sabriel, Lirael, and Abhorsen). The animal companions in these books aren’t simply cute or reassuring. In fact, not only are they directly relevant to the ongoing plot, but they become downright frightening at times, in their own way. They’re complex characters every bit as relevant to the story as the humans. (This is one of many reasons why this series of books is every bit as beautiful for adults as for young adults.)
Today, write about an animal companion–one you imagine for your own life, or for the life of a fictional character. Make the animal every bit as fully fleshed-out and relevant to the story or setting as any other character.
