Generosity: An Enhancement

FROM THE NATIONAL BOOK AWARD–WINNING AUTHOR OF THE ECHO MAKER, A PLAYFUL AND PROVOCATIVE NOVEL ABOUT THE DISCOVERY OF THE HAPPINESS GENE

When Chicagoan Russell Stone finds himself teaching a Creative Nonfiction class, he encounters a young Algerian woman with a disturbingly luminous presence. Thassadit Amzwar’s blissful exuberance both entrances and puzzles the melancholic Russell. How can this refugee from perpetual terror be so happy? Won’t someone so open and alive come to serious harm? Wondering how to protect her, Russell researches her war-torn country and skims through popular happiness manuals. Might her condition be hyperthymia? Hypomania? Russell’s amateur inquiries lead him to college counselor Candace Weld, who also falls under Thassa’s spell. Dubbed Miss Generosity by her classmates, Thassa’s joyful personality comes to the attention of the notorious geneticist and advocate for genomic enhancement, Thomas Kurton, whose research leads him to announce the genotype for happiness.


Russell and Candace, now lovers, fail to protect Thassa from the growing media circus. Thassa’s congenital optimism is soon severely tested. Devoured by the public as a living prophecy, her genetic secret will transform both Russell and Kurton, as well as the country at large.

What will happen to life when science identifies the genetic basis of happiness? Who will own the patent? Do we dare revise our own temperaments? Funny, fast, and finally magical, Generosity celebrates both science and the freed imagination. In his most exuberant book yet, Richard Powers asks us to consider the big questions facing humankind as we begin to rewrite our own existence.
