All right. The title excapes me, but I remember some key details. There is a family ( can't remember if british or not) and one of the children is in contact with an alien race ( they are white, very pale, bald humanoids, and I believe they are good). There is another race ( also humanoid, normal looking, but wear black body suits with very long/ tall helmet like things apart of their suits) and I believe they are an evil race. The white aliens warn the kid of the other race. His parents are killed I believe ( the kitchen looked like a massacre) and the boy and maybe his sister are taken and saved by the white bald aliens. That's all I know. I need the title!
