To be Perfectly Clear — Susan Butler

An invisible girl-a life of secrets and danger-Alison's adventures begin here...Fourteen-year-old Alison and her sister Amber don't lead the lives of typical teenagers. With no idea who their father is and their mother taken from them by force, they survive on their own. They rarely leave the house, too frightened to encounter those who don't share their defining feature - they are invisible.As part of an invisible society governed by an undercover council, they must abide by its #1 law: don't reveal your key trait. For those who don't obey, the punishment is said to be merciless, the fate that awaited their mother six years ago when she broke the rule. The girls remain in the safety of their attic hideaway and plan to stay there, until . . .. . . fate has other ideas for Alison and Amber. In need of a new way of life, they are happy to find friends, excitement, and fun. But a possible deception leads them on a perilous adventure, where secrets and danger lurk around every corner. Soon, the council's underlying agenda comes into question. And when those in power are invisible you never know who may be watching.
