Watch Your Mouth
is an American novel by Daniel Handler
about Joseph, a young student staying at the home of his girlfriend, Cynthia Glass, one summer. He has described it as an "opera in book form".
The first part of the novel is laid out as an opera
, with act and scene numbers as chapter titles and each of the characters being assigned a singing voice. Joseph quickly begins to suspect that Cynthia's entire family is engaging in incestuous
behaviour, and that her mother, Mimi, is building a golem
in the basement. The first part of the novel ends (operatically) in death. The second part is presented somewhat more conventionally, as Joseph attempts to recover from the events of the first part; this half of the book follows the form of a 12-step program
