This is a wonderful book. Dr. Bondar provides an astonishing breadth and depth of information on sex and mating in the animal kingdom in a highly readable and remarkably wise and funny way. Each chapter is short and self-contained, but the book also pulls together its themes. She derives and explains principles, gives examples, and notes counter-examples. The book shows a passion for getting the facts right, and notes points on which science has not yet answered all the questions. Any number of myths and misconceptions are exposed. There also are moments that startled me, made me flinch, or made me go ew!, but they all are on topic and earned. In all likelihood,there will be dozens of facts in this book that will strike you as so interesting that you will be mentioning them for months. I know I will re-read the book because there is just so much worth reading here and so much that is mind blowing that I could not take it all in on one go-through. This is the book equivalent of whom you wish would occupy the empty seat next to you on a long plane flight, if you're in the mood for a great conversation.
