I will never forget you, Masaccio, my best and only friend.‘ A young lonely girl called Nina writes these words after her pet cat, Masaccio, disappears. When he comes back to her as a ghost, she finds out that he needs her help. His remains are lost in a very strange place, so she must follow the ghost on a journey to bring him home. This is a beautifully illustrated, touching, but spooky and fun, tale about the enduring bond between us and our animal friends.
