A BIG story about a small boy who sees the world a little differently. Nine-year-old Milo Moon has retinitis pigmentosa: his eyes are slowly failing and he will eventually go blind. But for now he sees the world through a pin hole and notices things other people don't. When Milo's beloved gran succumbs to dementia and moves into a nursing home, Milo soon realises there's something very wrong at the home. The grown-ups won't listen to him so with just Tripi, the nursing home's cook, and Hamlet, his pet pig, to help, Milo sets out on a mission to expose the nursing home and the sinister Nurse Thornhill.
