I was thinking today about this set of short stories, but I can't remember what they were or who wrote them!
One of the stories was about a strange family, where each member has some sort of dark supernatural power, except for one boy who was 'normal'. Then another story had a man with wings, and it ends up he was a member of this strange family...
Shirley Jackson? (She's more into the horrors of real life...) Stephen King? (The stories seem a little dated for him...) Bradbury?
