The Sparky Book is a 2006 animated/live-action short film by Newfoundland filmmaker Mary Lewis, about the near-death of a young girl who undergoes heart transplant surgery, and the death of her beloved pet dog, Sparky.The story is based on the experiences of the director's own sister, Leah, who had two kidney transplants as a child. Michael Winter wrote a short story The Sparky Book after their dog had died. Director Lewis then loosely based her film on the short story.
