My Sister Lives On The Mantlepiece by Annabel Pitcher
Ten-year-old Jamie Matthews has just moved to the Lake District with his Dad and his teenage sister, Jasmine for a 'Fresh New Start'. Five years ago his sister's twin, Rose, was blown up by a terrorist bomb. His parents are wrecked by their grief, Jasmine turns to piercing, pink hair and stops eating. The family falls apart.
