Part Benjamin Button, part Harold and Maud, part Brian Selznick and part Neil Gaiman, this is a unique, magical story that will draw readers in and make them fall in love with both characters.     Davy David is a thirteen-year-old orphan, who lives in the bushes in a town ruled by a strict minister, Reverend Fall. A talented artist, Davy loves to draw pictures of angels in the dirt, in the early hours of the morning before the townspeople are awake. He spends his days on his own, except for a small dog, who has attached himself to Davy, often going to the library to find inspiration for his pictures of angels. One day, after chasing after a ball for some of the town's boys, he finds himself in the yard of the old boarded-up museum, now rumoured to be the home of a witch. The witch is Miss Elizabeth Flint, an elderly woman who has a proposition for Davy: drive her to her childhood home, where, it turns out, she has made the decision to die.
