It's a very well-written book with a fascinating focus on falling. It is not light-hearted, despite the fact that Buster Keaton is heavily featured. The obsession with Keaton is woven throughout the story, as the self-destructive narrator navigates her fraught relationships with her twin brother and her mother, as well as the family's superstitions about a falling curse supposedly caused by the actions of an ancestor in Prague. There are many interesting scenes set in Prague, where the narrator and her brother move for a while in an attempt to sort things out.
