"Epigenetics explains all this in clear, no-nonsense
prose. . . . One particularly excellent chapter explains epigenetic
change through the body of steroid-addled baseball player Jose
Canseco, from his brain to his testicles." -- Josh Rothman - Boston
"Francis's primer introduces a new field. It's a thorough guide to the many ways in which personality and health can play out through our genes but not be coded for in DNA." -- Christine Kenneally - Slate
