Books about genetic engineering

Books where heredity is rewritten or examined: engineered creatures, altered people and the science behind them. Michael Crichton's Jurassic Park brings dinosaurs back from ancient DNA, Daniel Keyes's Flowers for Algernon tests an experiment on human intelligence, and Siddhartha Mukherjee's The Gene tells the history of the idea itself. Rebecca Skloot's The Immortal Life of Henrietta Lacks shows the human cost of research.
