This is a story set in 1954, a year after the coronation of Queen Elizabeth II. It's spring time in a suburban area of 'The Big City'. There is a mysterious wood, a secret camping expedition, a graveyard, wildlife-rich ponds and pea-soup fogs. Three creative children with unusual families are targeted by a strange force, which causes them to gradually shrink. Eventually, they are the size of dust particles as they come face to face with earthly monsters and an alien species. This nightmare scenario forces them into many dangerous adventures and their problems are not solved until the very last chapter. Even then there are questions. Will they grow back normally? How will they react to fame? How will they be treated at school? The psychiatrist, Henry Osman, will have to play a big part in their rehabilitation.
