“This hotel-room picture was the first seed of an idea for a flying project. Henry was about six months old, and I was shooting a wedding in Princeton, New Jersey. I saw my husband flying Henry and it was graphically very interesting to me. I started contemplating a project where I'd remove the parent. This one was actually sort of eerie. I thought maybe it would be this spooky series, which it may have turned into had it not become a children’s book.”
