Generosity: An Enhancement is the tenth novel by American author Richard Powers. Like other Powers novels it is idea-driven, strongly focusing on social alienation and scientific progress. The novel employs metafiction, including real-time intrusions by the narrator who explicitly sets the novel in a "parallel" Chicago.Generosity tells the story of Thassadit "Thassa" Amzwar, an Algerian refugee who seemingly has overwhelming happiness ("hyperthymia") written in her genes, and the confounding effects she has on those around her, both sincere and exploitive.
