In this short-chapter winner of the IRA Children's Choices, Peter and Martin enjoy living atop Popcorn Hill, except for two things: They long for a big dog and their cabin is haunted by a lonely ghost. They do get a frisky mutt named Rosie, but she's not as big or as appealing as the stray sheepdog that has been roaming around outside. When the boys learn the sheepdog is a ghost, however, they devise a plan for bringing the two ghosts together. In the process, they learn to appreciate their real pet, Rosie.
