Bøker i Mo and Lottie-serien

Mo Appleby's ordered life is turned upside down when he and his mum move in with his new stepdad and stepsisters, Lottie and Sadie. The home he left behind is just across the street, and there's something not quite right about the new occupant. Who are the weird new people in their town? And why does the ice cream taste so good?
