Flesh and Blood by Chris Priestley
During the Blitz, Bill wishes he had a brother rather than his sister. After the raid, the family find and adopt a badly mutilated boy, his face so heavily bandaged that they can see nothing but his eyes. But the boy's behaviour grows more and more sinister by the day until one day he takes off the bandages - and Bill is horrified to see his own face staring back at him...A historical chiller. Particularly suitable for struggling, reluctant and dyslexic readers aged 10+
