Generosity: An Enhancement
2009 novel by Richard Powers

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.
Plot summary
Thassa is taking a class in creative non-fiction writing taught by Russell Stone. Her boundless happiness leads the class to dub her "Miss Generosity", but puzzles and disturbs Stone, who discusses Thassa with a college counselor, Candace Weld.
A classmate tries to rape Thassa one evening, she cheerfully talks him out of it, and he turns himself in for attempted rape. Police questioning leads to news of Thassa's "condition" becoming known, and her story becomes an Internet hit. A media circus and a scientific frenzy, led by geneticist Thomas Kurton, converge on her. Stone and Weld become lovers.
