Lottie Baker had Bill and her dog Pog. That was more family than a nine-year-old girl could ever need. She didn't need a mother, did she? Besides, their house was already way too crowded without trying to squeeze anyone else in. But then Lottie meets a runaway ghost called Martha May Claringbold, who is not too young and not too old. Martha doesn't want to live in the graveyard anymore because it's dark and smelly, and full of rotting bodies and old bones. She wants to live in Lottie's room because once upon a time Lottie's room was her room. A charming, tender and big-hearted upper middle grade novel from the bestselling author of the Billie B Brown, Hey Jack! and The School of Monsters series, and the current Australian Children's Laureate.
