#hardcover Advance praise for Gay, Straight, and the Reason Why "This book is the best available summary of the science of sexual orientation. I was struck reading it how much has happened in the field since LeVay's last book, Queer Science. It will be useful both to a general reader- -Simon is such a clear explainer- and to a specialist." -J. MICHAEL BAILEY, Northwestern University "LeVay offers a lucid, authoritative account of the exploding literature on the biology of hu- man sexual orientation. Gathering information from a dizzying variety of studies, encompass- ing genes, hormones, psychology, and the neurosciences, LeVay brings into sharp focus the overwhelming evidence that nature has a say in whom we love -S. MARC BREEDLOVE, Michigan State University "The question of how people become gay or straight is fraught with controversy, yet Simon LeVay has the remarkable ability to tackle chis subject in a lively, engaging, and balanced way. He carefully reviews the literature about sexuality and sexual orientation and presents his views crisply, thoughtfully, and always with a touch of humor. There are no axes to grind or political agendas at work here: LeVay dispassionately offers a model of sexual orientation that brings together key research findings. This book is compelling, enjoyable reading and a must for anyone interested in the biological bases of sexual orientation. •BRADLEY COOKE, Neuroscience Institute, Georgia State University "Simon LeVay provides us with yet additional evidence of both his mastery of the research literature on sexual orientation and his skill at writing about science so that non-scientists can appreciate it. This book should be mandatory reading for everyone needing to understand the evidence for the biological basis of sexual orientation- -legislators, members of the clergy, journalists, pundits, and parents." DENNIS MCFADDEN, University of Texas at Austin "Few scholars are as intellectually well-positioned as Simon LeVay to synthesize the prolifera- tion of scientific research on sexual orientation that has blossomed since the publication of his pioneering brain study twenty years ago. This book is rigorous, insightful, and balanced. It provides a welcome antidote to the uninformed debate on this topic, which seems all too rife." -PAUL L. VASEY, University of Lethbridge
