Jedediah's father walked out of his life forty years ago. Now he's back. He won't apologise, he doesn't explain - and, impossibly, he hasn't aged a day.
If you asked the folks of Gyrford, they'd tell you Jedediah Smith looked up to his father. After all, Corbie Mackem was the Sarsen Shepherd: the man who saved the Smith clan from Ab, the terrifyingly well-meaning fey who blighted a whole generation with unwanted gifts.
Corbie was a good fairy-smith. And if he wasn't a good father, well, that isn't something Jedediah likes to talk about. Especially since no one knows where Corbie's body lies: the day of his son's wedding, forty-odd years ago, he set off to travel and was never seen again.
