The idea of writing William and Tibby Forever came after Lynda’s cat, William, was killed. She was so saddened by the loss and thought how it must be for other people, especially for kids losing their pet, or a person for that matter. So she decided to write a children’s picture book about William’s death. However, when she sat to write the story, Lynda realized that she had already written 10 pages, not yet including the part where she meets William. It was then that she made a decision to write a full novel about William.
