This is the story of a very normal girl on an almost normal night in a fairly normal house. Normal that is except for a not-so-normal clock whose numbers count not to twelve but to a spooky thirteen. An extraordinary book about the antics of a perks prankster in paijamas. Filled with sly word play rich langauge, atmospheric illustrations, that remind us that things are not always as they seem and there is more than fright to be had from things that go bump in the night!
