'Let's face it. David Perrett has written a truly compelling book. Chock full of science, but reader-friendly and entertaining. Now I have a new perspective on my own crooked smile and have learned many other fascinating things related to faces. Highly recommended.' Professor Joseph LeDoux, author of The Emotional Brain and Synaptic Self. 'An engaging revelation of the biology and psychology behind facial beauty, but be warned: In Your Face may reveal some surprising truths about why we are attracted to others.' Bruce Hood, author of SuperSense and Professor of Experimental Psychology at the University of Bristol. '[An] exuberant account from the frontiers of science.' - Human Givens
