A sweet and gentle story about sisters, trust, parrots, disappearing . . . and doing the right thing. Eight-year-old Izzy is more curious, playful and clumsy than her serious, grown-up sister Carrie. In fact Izzy is much more like Gran, an eccentric scientist who has a house full of weird and wonderful pets. But when one of Gran's experiments backfires, Izzy discovers that she has the ability to become invisible! That is, unless Perky the parrot is perched on her shoulder, or she has one of his feathers safely stowed in her pocket. Yikes! While Gran searches for an antidote, Izzy explores her invisibility - to her and Perky's amusement - but Mum, Dad and Carrie aren't impressed. Can Izzy prove that she is using her invisibility to help those around her, and regain her sister's trust?
